Southern Saskatchewan is a fine place to capture nightscapes of the Milky Way over the grand prairie landscape.
In late August 2025 I took a short road trip around southwest Saskatchewan, taking advantage of a run of wonderfully clear nights to shoot “nightscapes” at some of my favourite locations.
Southern Saskatchewan, and more specifically Southwest Saskatchewan, is a stargazing paradise. The skies are dark and there’s nothing to get in the way of seeing them! Yet, the landscapes have their unique beauty.
And in the case of Grasslands National Park the landscape preserves the endangered realm of original short-grass prairie. It is what the land was like long ago, even including some bison at large.
Grasslands National Park
Technical: This is a blend of tracked and stacked sky exposures with a single untracked ground exposure: – 7 x 60 seconds at f/2 tracked and focused for the sky, plus – 1 x 4 minutes at f/2.8 untracked and focused for the foreground to bring out the details lit only by starlight. No light painting was employed here. – All with the Nikon Z8 at ISO 800 and Nikkor 20mm S lens, on the MSM Nomad tracker. And all from the same tripod position. However, the camera was reframed upward for the sky shots.
In fact, my main destination on my visit to Grasslands this year was to revisit a site I had intended to shoot from in 2019 – the Bison Rubbing Stone overlooking the Frenchman Creek Valley, with the Milky Way as a backdrop.
This year I was assured the bison were in the outback, so I set up at their rubbing stone. This is one of the many glacial erratic boulders the Ice Age left scattered across the prairies. With no trees about, the bison have long loved to use them to scratch an itch. But the connection with the stars is that one legend of the sky told by Blackfoot First Nations describes the Milky Way as the “Buffalo Trail,” the dust left by a cosmic herd of bison.
I got the shot! Then all I had to do was turn the camera around to face north to get this scene.
Technical: This is a panorama of 5 segments, each 30 seconds untracked at f/2 with the Nikkor 20mm S-Line lens and Nikon Z8 at ISO 1600. Stitched with Adobe Camera Raw. I removed aircraft trails, but at left I retained the many faint satellite trails in the northwest still lit by twilight, as this was early at about 10:30 pm CST. I did not focus stack these frames. Nor was the camera tracking the stars.
A mild aurora appeared in a classic arc across the north, and framed between the hiking trail, with the Big Dipper to the left and the Milky Way rising to the right. This is the wonderful sky that awaits in the “big sky” country of Grasslands. On the horizon only 3 distant lights could be seen. Grasslands is a Dark Sky Preserve. May it always be so!
Technical: This is a blend of tracked and stacked sky exposures with a single untracked ground exposure: – 4 x 30 seconds at f/2 tracked for the sky, plus – 1 x 2 minutes at f/2.8 untracked for the ground to bring out the details lit by starlight, plus – A single 30-second tracked exposure through a Tiffen Double Fog 3 filter layered in, to add the star glows. – All with the Nikon Z8 at ISO 800 and Nikkor 20mm S lens, on the MSM Nomad tracker. And all from the same tripod position. The camera was not moved for the sky photos.
The night before I headed south out of the little town of Val Marie to a favourite spot high on the hill overlooking the Park. It is called Two Trees, but now only one tree remains! It made a fine foreground for the classic “lone tree and Milky Way” nightscape.
In August the galactic centre lies in the southwest quickly setting in the early evening. But from this latitude of 49º N even with it at its highest, the Milky Way core lies low in the south, making for good compositions with foregrounds below.
Here I present a “landscape” version of the image above, in versions with and without labels to indicate all the rich nebulas and star clusters in this area of sky in Sagittarius the Archer, home of the Milky Way core. Tap on the images to bring them up full screen.
Similarly, below I present views looking east to the autumn constellations rising over the prairie. This was from the valley below Two Trees Hill, at the Riverwalk day use site. Here there were absolutely no lights visible, and hardly a sky glow on the horizon from towns and light pollution. This was paradise for a stargazing session.
The constellations in this area of sky are the ones made famous in the classic tale of the hero Perseus riding on Pegasus the Flying Horse to rescue the lovely Princess Andromeda from Cetus the Sea Monster, while vain Queen Cassiopeia looks on.
Here the sky was also tinted green, not with aurora but airglow, a natural effect caused by high-altitude oxygen fluorescing at night, giving off energy it has absorbed by day. It discolours the sky but it belongs there! It is visible only at dark sky sites.
The Great Sand Hills
From Grasslands I ventured north to the little town of Leader, Saskatchewan, one of the jumping off points to visit the Great Sand Hills nearby. You have to have a local map to find them, but the sand dunes are extensive, and an oddity on the prairie, another Ice Age relic.
They are not a Park but are an ecological reserve, with limited access. I shot from the main spot with parking for visitors and a trail off into the dunes.
Here is another pair of images with annotations, looking north from the main dune field toward Ursa Major and the Big Dipper.
An extensive display of airglow also tints the sky, at least I think that’s the source, and not aurora.
Technical: This is a blend of tracked and stacked sky exposures with a single untracked ground exposure: – A stack of 4 x 60 seconds at f/2 tracked for the sky, plus – 1 x 4 minutes at f/2.8 untracked for the ground, plus – A single 60-second tracked exposure through a Tiffen Double Fog 3 diffusion filter layered in, to add the star glows. – All with the Nikon Z8 at ISO 800 and Nikkor 20mm S lens, on the MSM Nomad tracker. And all from the same tripod position. However, the camera framing was changed for the sky and ground shots, tilting it up it to include more of the sky up the northern Milky Way.
Turning around to face south again frames the sweep of the summer Milky Way over the well-trodden dunes. Not quite the Saharan or Namibian scene you might want, but this is Saskatchewan and having even this scene on the prairies is unique. The only other dune fields are far up north and not readily accessible.
Technical: This is a blend of tracked and stacked sky exposures with a single untracked ground exposure: – A stack of 4 x 60 seconds at f/2 tracked for the sky, plus – 1 x 3 minutes at f/2.8 untracked for the ground to bring out the details lit only by starlight, plus – A single 60-second tracked exposure through a Tiffen Double Fog 3 diffusion filter layered in, to add the star glows. – All with the Nikon Z8 at ISO 800 and Nikkor 20mm S lens, on the MSM Nomad tracker. And all from the same tripod position. However, the camera framing was changed for the sky and ground shots, tilting it up it to include all the constellations in one frame but with just a sliver of ground in the frame.
Looking east from the dune again frames the mythological autumn constellations, with the “W” of Cassiopeia at top amid the Milky Way. The bright “star” at lower right is Saturn. The Pleiades are just rising at left.
The Cypress Hills
I had started my Saskatchewan journey in the Cypress Hills, another formation created by the Ice Age, or rather left untouched by the glaciers creating a high wooded oasis on the prairie. I was there for the annual Saskatchewan Summer Star Party, the subject of my previous blog here.
Technical: This is a blend of: – A stack of 4 x 1 minute exposures, tracked, for the sky with … – A stack of 2 x 1-minute exposures, untracked, for the ground, – All with the Canon RF 28-70mm lens at f/2 and set to 48mm, on the astro-modified Canon EOS R at ISO 1600, and on the MSM Nomad tracker. No filters were employed here. Masking and blending all the images, with the trees in the foreground was a challenge! The camera was not moved — all images were from the same tripod position.
But on the first couple of nights, with the entire four nights of the Party promising to be clear, I left the Party and headed off on my own to shoot some nightscapes over the pine trees at Lookout Point, to again catch the photogenic galactic core in its last appearance for the season.
For the image below, I employed a special filter that isolates the deep red light emitted by the many hydrogen-gas nebulas toward the Milky Way core.
Technical: This is a blend of: – A single 2-minute exposure, untracked, for the ground, blended with … – A stack of 5 x 1 minute exposures, tracked, for the sky, plus … – An additional tracked 2-minute exposure layered in, taken at the end of the set through an Astronomik “narrowband” H-Alpha clip-in filter, to add the red nebulas. – All with the Canon RF 28-70mm lens at f/2 and set to 35mm, on the astro-modified Canon EOS R at ISO 1600 (3200 for the Ha shot), and on the MSM Nomad tracker. Masking and blending all the images, with the trees in the foreground was a challenge! The camera was not moved — all images were from the same tripod position.
This is a technique borrowed from “deep-sky” imaging but now popular among nightscape photographers to create an even more enhanced night sky than a normal unfiltered view.
But even without the filter the long exposures used for the sky record far more detail and colours than even dark-adapted eyes could see. The filter takes that even further.
But those nebulas are there, and they do glow red. Just like the airglow that unaided eyes usually cannot see, the long exposures reveal the unseen, in this case some of the wonderful content of our Galaxy.
And that’s the attraction of astrophotography, to reveal the otherwise elusive or invisible structure of the sky, and in this case juxtaposed over familiar earthly landscapes below.
I can highly recommend Southwest Saskatchewan for anyone interested in stargazing and astrophotography. It’s always been one of my favourite destinations.
It took a last-minute chase, but I managed to capture the total eclipse of the Moon on March 14, 2025.
It would not be an eclipse without a chase. Solar eclipses of the total kind almost always involve travel, often to exotic locales around the world. But total lunar eclipses come to you, as they can be seen from an entire hemisphere of the planet.
Except there’s one problem — clouds! Over the last decade since 2014, of the eight total lunar eclipses (TLEs) I was home in Alberta for, I had to chase into clear skies for all but one. A recounting of one such chase from January 2019 is here.
Only for the TLE before this most recent (on November 8, 2022) was I able to stay home to watch it. Though in that case a snowstorm the day before made the roads and travel poor, so I had to stay home. I recounted that eclipse story here. You’ll find links to my other lunar eclipse stories below.
Once again, for the March 13/14, 2025 TLE, weather prospects looked poor. Not just in my area but in many regions of the continent. But there was hope!
Astrospheric and Environment Canada cloud forecast + Moon information
The forecast cloud cover showed home to be hopeless. But a clear area was supposed to be open in southwestern Alberta, marked by the red circle above. That’s Waterton Lakes National Park, just on the US border. It’s a favourite place of mine for nightscape photography anyway (see my blog from this past summer here).
The chart above from the app Astrospheric shows the clear hole, and the dark blue on the time-line indicates the period with no clouds. Note how it coincides with the wavy line below which shows Moon altitude, with the orange and red regions indicating when the eclipse would take place. Looks good! So I made my plan to chase.
I knew the area well enough to know the site would be a good one for the eclipse, and the Moon’s location to the south. But it pays to check. I use The Photographer’s Ephemeris as my main photo planning app.
TPE Plot of Sightlines
It showed the sightline toward the Moon during the eclipse as straight down Upper Waterton Lake. My chosen spot was on the lakeside Waterton Avenue, where I could set up both the wide-angle camera and a telescope without having to heft gear any distance. Winter road closures also limited my site choices. Indeed, in winter the Park is quiet, with only a few hotels and restaurants open, and many businesses boarded up.
TPE 3D Simulation
Switching to the companion app TPE 3D (above) showed a preview of the landscape and the Moon’s position in the sky relative to the scene below.
Compare the simulation to the real thing below! Pretty accurate, except for the scattered clouds that drifted through.
This is a blend of separate images for the sky and ground: a stack of two untracked images for 60 seconds each for the ground, then a third exposure for the sky and untrailed stars, taken immediately afterwards with the tracker motor on, for 30 seconds, all with the Canon RF15-35mm lens wide-open at f/2.8 and at 20mm, on the Canon R5 at ISO 1600. Separate shorter tracked exposures of 15, 8 and 4 seconds blended in kept the lunar disk from overexposing, showing it more as the eye saw it.
The above image is a blend of tracked exposures for the Moon and sky, with untracked exposures for the ground. I shot them just before mid-totality at 1 am MDT. That image was second in priority. First, was a panorama. That result is below.
This is a panorama of four segments at 30º spacing, taken in two passes: first untracked for 30 seconds each, then a second pass immediately afterwards with the tracker motor on, also for 30 seconds each, all with the Canon RF15-35mm lens wide-open at f/2.8 and at 20mm, on the Canon R5 at ISO 1600, with the camera in landscape orientation. Separate shorter exposures of 15s, 10s, 5s and 2.5s at ISO 400 were blended in to preserve the lunar disk more as the eye saw it.
I shot this scene just as totality began, to ensure I got it. While the Moon was in clear sky before totality during the partial phase, sure enough as the Moon became fully eclipsed, the clouds wafting over the mountains threatened to move in and obscure the view.
Luckily, while they did hide the Moon now and then, they opened up enough for good views and images for a few minutes at a time throughout the eclipse.
For the panorama I processed the image for a more monochromatic look, to resemble the naked-eye view, but with the Moon appearing as a red globe in the sky, the only colour in the scene. (I shot the tracked shots with the MSM Nomad tracker I reviewed here.)
The site proved excellent, but it was a cold night! While the temperature was only just below freezing, the brisk Waterton wind off the lake made it a chilly experience watching the eclipse for two hours. I was actually being hit by ice pellets blowing off the lake.
I decided not to set up the telescope for close-ups; the wide-angle images were the priority anyway from such a scenic spot.
A single untracked 15-second exposure with the RF15-35mm lens at f/2.8 and 17mm on the Canon R5 at ISO 3200.
But I am not complaining. I got the eclipse, once again by chasing to where the weather predictions said it would be clear. The above is my requisite trophy shot.
Had I stayed home I would have been clouded out. Had predictions called for clear skies at home, I would not have made the trip to Waterton to enjoy the eclipse over its wonderful scenery.
The next total lunar eclipse is September 7, 2025, six months after this eclipse. But it is visible from the opposite hemisphere to this one, with no part of that eclipse visible from North America. I will not chase that far for a TLE!
The March 3, 2026 TLE from Alberta
After that, and after a passage of one lunar year (355 days or 12 lunar cycles) since the March 14, 2025 TLE, I have a chance for another total lunar eclipse from home, with western North America favoured. As I preview above, it’ll be an early morning event on March 3, 2026, with the eclipsed Moon setting in the west in the pre-dawn hours.
Sounds like another chase to a mountain site with the red Moon over the Rockies. That’ll be the plan!
A plan to shoot the promised bright comet of 2024 paid off, with fine views at dawn and at dusk of the best comet since 2020.
Comets are always a gamble. Any new comets discovered, the ones that usually become the brightest, have no track record of performance. Predictions of how bright a new comet might appear are based on what a typical comet should do. But comets can outperform expectations and dazzle us, or they can fizzle and fade away.
In late 2023 it was clear that a then newly-discovered comet, C/2023 A3, named Tsuchinshan-ATLAS after the observatories where it was co-discovered, had the potential to perform in late 2024.
The low angle and position of the comet from home in Canada in the late September dawn sky, simulated in StarryNight software.
Knowing where it would be in the sky (that trait of a comet can be predicted with accuracy!) I planned a field trip to the U.S. desert Southwest for late September and early October 2024. From farther south the comet would be higher than it would be from home (shown above), and over spectacular landscapes.
I had visions of another Comet NEOWISE from July 2020. As my blog from 2020 shows, we saw that photogenic comet well from our northern latitude in Canada, as it skimmed across the northern horizon. Tsuchinshan-ATLAS would require a chase south.
September 26 & 27 — at Bryce Canyon, Utah
In late September 2024 the comet would be inbound, approaching the Sun and in the morning sky. What better eastern scene than overlooking Bryce Canyon in Utah, where I had been a year before, for the October 14, 2023 annular eclipse of the Sun in the morning sky. (Click the link for my eclipse chase blog.)
I was fortunate to get two clear mornings, both from the Fairyland Canyon viewpoint, just a short walk from the parking lot to carry camera gear and tracking mounts.
Comet C/2023 A3, Tsuchinshan-ATLAS, at dawn over Bryce Canyon, on the morning of September 27, 2024.
My first look at the comet on September 27 was on the day the comet was at perihelion, closest to the Sun in its orbit, though not in the sky at our viewing angle from Earth.
The comet was just visible to the unaided eye, but was obvious on the camera view screen, even amid the bright twilight. I had to shoot fast as the window between “comet rise” and the sky brightening too much was only a few minutes long.
Comet C/2023 A3, Tsuchinshan-ATLAS, rising in the twilight over Bryce Canyon, on September 28, 2024.
Knowing better what to look for, I caught the comet a little sooner the next morning on September 28, and so the tail appeared longer and more impressive as it rose above the distant mountains. A group of other local photographers arrived just a few minutes too late both mornings, and so struggled to just sight the comet, let alone photograph it.
This vertical panorama takes in the nebula-rich northern winter Milky Way over the formations of Bryce Canyon National Park, from the Fairyland Canyon viewpoint.
But I had arrived extra early, to shoot a vertical panorama (above) of the winter Milky Way over the canyon formations below. This and the comet images were shot with the aid of a sky tracker to follow the stars, but with the tracker off for separate shots of the ground.
So I had bagged the comet at Bryce! On to the next stop.
September 28 & 29 — at Monument Valley, Utah
There’s no more iconic or famous landscape in the American West than the buttes of Monument Valley, on the Navaho Tribal Lands on the Arizona/Utah border.
This panorama from the Navaho Tribal Park at Monument Valley shows the evening twilight sky looking east opposite the sunset to the rising dark blue arc of Earth’s shadow cast on the atmosphere. The shadow is rimmed with a pink “Belt of Venus” tint from sunlight still hitting the upper atmosphere.
A clear first evening provided a fabulous view of the arc of Earth’s shadow across the eastern sky from the viewpoint near the aptly named The View Hotel.
This is a panorama of the sunrise scene at the Navaho Tribal Park, Monument Valley, Arizona, taken just after sunrise with the low Sun lighting the iconic buttes and mesas of the Valley. The West and East Mittens are at left; the Sun was behind Merrick Butte at centre, and lighting Mitchell Mesa at right.
A wonderful sunrise on my second morning there made for a spectacular panorama. But while clouds created fine sunrise lighting, they aren’t conducive to seeing comets!
Comet C/2023 A3, Tsuchinshan-ATLAS (at centre), is rising in the dawn twilight over Monument Valley, Arizona on the morning of September 30, 2024. The comet is rising just south (right) of Merrick Butte.
A band of clear sky near the horizon allowed me to catch the comet rising to the right of Merrick Butte, as seen from a spot south of The View from where I had calculated the comet would rise in the right position. From the usual Valley viewpoint farther north the comet would have been behind the butte.
While the planning worked, the result was not quite the spectacle I had envisioned. The comet was nice, but was starting to become lost in the bright sky as it descended toward the Sun.
There were only a couple of mornings left to catch the comet at dawn before it disappeared completely into the daytime sky close to the Sun.
October 1 to 11 — at Quailway Cottage, Arizona
The major block of time in my trip was booked for an astrophoto retreat at a cottage I’d rented twice before but not since late 2017. The Quailway Cottage, popular among birders, is also ideal for stargazing as it is in one of the darkest areas of the Southwest, north of Douglas, Arizona, and just across the Arizona/New Mexico border.
This captures both the glow of Zodiacal Light in the eastern dawn sky (the band of light extending up across the frame) and the dust tail of Comet Tsuchinshan-ATLAS rising from behind the Pelloncillo mountains, at dawn on October 2, 2024.
When I arrived the comet was putting in its last show in the dawn sky. In fact, on October 2 I managed to capture a dawn scene with the morning Zodiacal Light created by sunlight reflecting off cometary dust in the inner solar system, and just the tail of the comet rising before the bright comet head appeared.
Comet C/2023 A3, Tsuchinshan-ATLAS, is rising in the dawn twilight over the Pelloncillo Mountains in New Mexico, on October 2, 2024.
An image taken a little later showed the entire comet, now sporting a more impressive tail. It was blossoming into a fine comet indeed. But we were about to lose sight of it for more than a week.
Arizona Deep-Sky Imaging
While at Quailway I had clear skies every night. And so, as planned, I went to town shooting all kinds of “deep-sky” objects and fields with two astrophoto rigs I had brought with me: a longer-focal length 120mm refractor for small targets, and a short-focal length refractor for wide fields in the Milky Way. I had reviewed both new telescopes in recent months.
The Askar APO120 on a veteran Astro-Physics AP400 mount. The Founder Optics Draco 62 on the small Star Adventurer GTi mount.
I concentrated on shooting targets low in the south that are impossible to get from home in Canada, and that I’ve missed shooting, or have not shot well, during my visits to Australia. See my blog here about my latest trek Down Under.
The two brightest Fornax cluster members are the elliptical galaxy NGC 1399 at upper left, paired with smaller NGC 1404, and the galaxy NGC 1365 at lower right, considered one of the best barred spirals in the sky.
Here’s an example, above, with the larger Askar 120APO: a field of galaxies in the constellation of Fornax that rivals the better-known Markarian’s Chain of galaxies in Coma Berenices in the northern spring sky.
This frames the spectacular region of the Milky Way near the direction of the galactic centre in Sagittarius.
And here’s a field (above) with the small Founder Optics Draco 62mm scope, framing the rich Sagittarius Starcloud punctuated with the small dark Ink Spot Nebula, all below the bright Lagoon and Trifid Nebulas.
This panorama extends for about 240º along the northern half of the Milky Way, from Orion at left, to Sagittarius at right, and centered on the Galactic Equator.
In autumn the Milky Way is up all night. So I used a simple star tracker, the MSM Nomad reviewed here on my blog, and a 28-70mm lens at 35mm to shoot a panorama from dusk to dawn along the Milky Way — from the summer stars of Sagittarius and Cygnus (at right, above), through the autumn constellations overhead in Cassiopeia and Perseus (at centre), and down into the pre-dawn sky with the winter stars in and around Orion (at left).
A Bonus Aurora from Arizona
I was just north of the Mexican border, at a latitude 32° North, more than 20° farther south than at home in Alberta. But what should appear in my sky but … aurora!
A selfie of me observing the great red aurora of October 10, 2024, from southern Arizona.
On October 9, and then again more so on October 10, a great solar storm brought Northern Lights down to me. And indeed across all of Canada and the U.S. The result for me was a red glow to the north — the tops of distant auroral curtains I would have seen filling my sky at home.
A time-lapse of an Arizona aurora, using a 15mm wide-angle lens shooting nearly 400 forty-second exposures. View it in-line here. Enlarge to a full screen view. There is no sound.
Above is a time-lapse video of the aurora that night, from a camera aimed due north for four hours. The red curtains come and go through the night.
This is a 360° panorama covering the entire sky and extending up to the zenith at centre, capturing a rare SAR arc across the Arizona sky in the pre-dawn hours of October 11, 2024.
The remarkable feature that night, October 10/11, was not the aurora, but what is called a SAR (Stable Auroral Red) arc that persisted all night. It appeared as a diffuse red band across the sky, created by heat energy leaking into the upper atmosphere during the solar storm. SAR arcs can accompany an aurora but are not auroras themselves.
This panorama takes in a rare confluence of skyglows in a colourful dawn sky.
By dawn the next morning, now October 11, the tall Zodiacal Light was prominent alongside the magenta SAR arc to the north (left) and the winter Milky Way to the south (right). There’s even a short pillar of light that might be an aurora fragment, or the tail of the comet!
The Comet Returns
However, toward the end of my 11-night marathon of deep-sky imaging, the bright head of the comet was to be rising into the evening sky for Part 2 of its apparition. Below is a shot from the evening of October 11, my last at Quailway. Yes, there it was, just above the Chiricahua Mountains. But it was a blip, barely visible in binoculars and to the camera. I had hoped for more.
This is Comet Tsuchinshan-ATLAS (C/2023 A3) at far right, barely visible emerging into the evening sky and low in the twilight, on October 11, 2024. This view includes Venus at left. Venus was obvious; the comet was not!
With the Moon now waxing into the evening sky, my plan was to head back north, stopping at scenic spots on the trip home, to catch the comet over moonlit landscapes to the west in the dusk sky.
My first two nights, October 12 and 13, at the VLA Radio Observatory near Socorro, New Mexico, then farther north near Canyon de Chelly, Arizona, were both beset by clouds to the west. From images posted on-line, I knew the comet was improving. But it was eluding me.
October 14 & 15 — at Arches National Park, Utah
The next stop was Arches National Park in Utah, which I last visited in April 2015. The first night’s forecast for October 14 also looked to be cloudy. But October 15 was supposed to be clear. So I extended my stay by an extra night, thinking that might be my only chance.
As it turned out October 14 was fabulous (below). The comet was easily visible to the unaided eye as a classic comet in the west. I pointed it out to folks walking by at the Windows Arches area. And I could hear other people commenting on it. At last a comet! One that anyone could see — though it helped to be at a clear sky site like Arches.
Comet Tsuchinshan-ATLAS at its finest in the evening sky, two days after its closest approach to Earth, and with it sporting a 10º- to 15º-long dust tail, and a narrow anti-tail pointed toward the horizon.
By then the Moon was well advanced in age to a bright gibbous phase, so the sky was by no means dark. It was deep blue in photos.
Still the comet showed up brilliantly; it had blossomed a lot in a couple of nights. Above, I framed it beside moonlit Turret Arch.
Below is a scene from the next night, October 15, my “back-up” night. The comet was certainly performing well after all. Even in the moonlight. In binoculars the tail stretched for the same length as the camera recorded it, some 15°.
This is a telephoto close-up Comet Tsuchinshan-ATLAS over the red rocks of Arches National Park, Utah, on a superb moonlit night, October 15, 2024.
Indeed, that was my last view of the comet for a while, as clouds prevented any more shooting on the rest of my journey north through Idaho and Montana. I even hit a snowstorm in southern Montana.
Late October — Back at Home in Alberta
But the comet was not done yet! Through October, while it receded from us in distance, it climbed higher into our sky, placing it into a dark sky with the Moon now out of the way.
This is Comet Tsuchinshan-ATLAS in a wide-angle nightscape scene over the Badlands of Dinosaur Provincial Park, Alberta, on October 23, 2024.
On October 23, a short trip out to Dinosaur Provincial Park east of home allowed me to shoot the comet over the Alberta Badlands landscape, beside the setting summer Milky Way.
This is a telephoto lens framing of Comet Tsuchinshan-ATLAS in Ophiuchus on the night of October 30, 2024 near several large star clusters. The field of view is 15º by 10º so the tail extends for about 6º to 8º.
By a week later, on October 30, the comet had diminished in size and brightness, but still looked like a classic comet, here framed in a telephoto close-up as it passed near some bright star clusters. This was from my front yard. The chase was over.
Clouds and a trip to Norway starting November 4 prevented more opportunities to shoot the comet. (My travel schedule also kept me from writing this blog until now!)
It had been a good chase over a month, yielding images I was happy with. The photos from Utah and Arizona I could not have taken at home, even if the skies had been clear during the comet’s prime-time. (They weren’t!) And it was great to finally get back to my favourite haunts in southern Arizona and New Mexico after an absence of seven years.
In all, Comet Tsuchinshan-ATLAS provided a fine finale to what has been a superb year of stargazing events and celestial sights.
I present a selection of new images taken at local World Heritage Sites, along with some advanced nightscape shooting tips.
I’m fortunate in living near scenic landscapes here in southern Alberta. Many are part of UNESCO World Heritage Sites that preserve regions of unique scenic and cultural significance. In early June I visited several to shoot nightscapes of starry skies over the scenic landscapes.
I also took the opportunity to experiment with some new shooting techniques. So I’ve included some tips and techniques, most of the advanced variety.
First up was Dinosaur Provincial Park.
The Milky Way and its core region in Sagittarius and Scorpius is here low over the Badlands landscape of Dinosaur Provincial Park, Alberta.
After nearly a month of rain and clouds, the night of May 31/June 1 proved wonderfully clear at last. I headed to a favourite location in the Red Deer River valley, amid the eroded badlands formations of Dinosaur Provincial Park, site of late-Cretaceous fossil finds.
The bright core of the Milky Way in Sagittarius would be in the south. With the night only three weeks before summer solstice, from the Park’s latitude of 50.5° N the sky would not get astronomically dark. But it would be dark enough to show the Milky Way well, as above in this framing looking south on the Trail of the Fossil Hunters.
However, May and June are “Milky Way Arch” months, at least for the northern hemisphere. The full sweep of the northern Milky Way, from Perseus in the northeast to Sagittarius in the southeast, then stretches across the sky — high enough to be impressive, but low enough (unlike later in summer) to be framable in a horizontal panorama.
This is a 200° panorama of the arch of the northern Milky Way rising over the Badlands landscape of Dinosaur Provincial Park, Alberta.
To capture the arc of the Milky Way I shot a panorama — in fact three:
one exposed for the ground
one exposed for the sky, but with the camera now tracking the sky to keep stars pinpoint
and a final sky panorama but with a specialized filter installed in front of the camera sensor to let through only the deep red light emitted by nebulas along the Milky Way
Rig for tracked panoramas with the MSM Nomad tracker
The image above shows my rig for taking tracked panoramas. The rectangular box is the little Nomad sky tracker from Move-Shoot-Move (MSM), here equipped with its accessory laser pointer to aid the “polar alignment” that is needed for this or any tracker to follow the turning sky properly.
A review of the MSM Nomad will be forthcoming (subscribe to my blog!). However, I’ve found it works very well, much better than MSM’s original Rotator tracker, which was entirely unreliable!
On top of the little Nomad is an Acratech pano head, so I can turn the camera by a specific angle between each pano frame, both horizontally from segment to segment, and vertically if needed when raising the camera from the ground pano to the sky pano.
The pano head is on a “V-Plate” sold by MSM and designed by the late, great nightscape photographer (and engineer by trade), Alyn Wallace. The V-Plate allows the camera to turn parallel to the horizon when on a tipped-over tracker. The entire rig is on a Benro 3-Axis tripod head (also sold by MSM, but widely available) that makes it easy to precisely aim the tracker for polar alignment and then hold it rock steady.
The H-Alpha Panorama rendered in monochrome
I’d taken many panos before using sets of untracked ground and tracked sky panoramas. New this night was the use a “narrowband” Hydrogen-Alpha filter to take a final pano that brings out the red nebulas. I used a filter from Astronomik that clips into the camera in front of the sensor. Such a filter has to be used on a camera that has been modified to be more sensitive to deep red light, as the Canon Ra shown below is (or was, as Canon no longer makes it).
While a modded camera brings out the nebulas, using an H-Alpha filter as well really shows them off. But using one is not easy!
Astronomik clip-in filters, the 12nm H-a on the right
The clip-in placement (unlike a filter in front of a lens) requires that the lens be refocused — infinity focus now falls at the 3 to 6 metre point (the focus shift varies with the lens and focal length — the wider the lens the greater the shift). With the image so dark and deep red, seeing even a bright star to manually focus on is a challenge.
Shifting the lens focus also changes the overall image size (called “focus breathing”) and often introduces more off-axis lens aberrations, again depending on the lens.
So, blending the H-Alpha pano (which I rendered out in monochrome, above) into the final stack is tough, requiring lots of manual alignment, image warping, BlendIf adjustments, and masking. This is where I added in the red colouration to taste. Careful here, as the “Saturation Police” patrolling social media will issue tickets if they judge you have exceeded their “speed limit.”
The complete panorama with Photoshop layers and adjustments
The final pano required a complex blend of image and adjustment layers, all applied non-destructively, so the many elements of the scene can be individually tweaked at any time.
The work was worth it, as the final pano records the deep red nebulas contrasting with the deep blue of a sky still lit partly by twilight, a magenta aurora to the north, and bands of green and yellow airglow, all above the earth tones of the Badlands. It is one of my favourite nightscape panoramas.
As a further note on software: For stitching panos I try to use Adobe Camera Raw first. It can work very well. But complex panos, especially taken with very wide lenses, often require the specialized program PTGui, which offers more choice of pano projection methods, cleaner stitching, and control of panorama framing and levelling.
Next up was Writing-on-Stone Provincial Park.
A week later, with the waxing Moon beginning to appear in the western sky and the promise of clear nights, I headed south to the 49th parallel borderlands of the Milk River and Writing-on-Stone Provincial Park, known as Áísínai’pi to the Blackfoot First Nation who revere the site as sacred.
My plan was a framing of the galactic centre over the Milk River valley and distant Sweetgrass Hills in Montana, perhaps using the H-Alpha filter again. But clouds got in the way!

When you are faced with a cloudy sky, you make use of it for a colourful sunset. I like shooting panoramas at such sites as they capture the grand sweep of the “big sky” and prairie landscape. Above is the scene at sunset.

Above is the same scene a few minutes later as the Sun, though now set, still lights the high clouds with its red light, mixing with the blue sky to make purples. On the hill at right, a couple admires the sunset, adding a human scale to the vast skyscape.
This pano was with the Canon RF15-35mm lens at 15mm and the camera in portrait orientation to capture as much of the sky and ground as possible in a single-row pano.

I finished the evening with another panorama, but using a Canon RF70-200mm telephoto lens at 70mm to zoom in on the Sweetgrass Hills in the deepening twilight.
Rig for untracked panoramasPanorama head close-up
For these panoramas, exposures were short, so I didn’t need to track the sky. I used another combination of gear shown above. An Acratech ball head sits atop another style of panorama head that has adjustable click stops to make it easy to move the camera from segment to segment at set angles. When the lighting is changing by the second, it helps to be quick about shooting all the pano segments. Such pano heads are readily available on Amazon.
That pano head sits atop an Acratech levelling head (there are many similar units for sale), an essential addition that makes it easy to level the pano head so the camera turns parallel to the horizon. Any tilt will result in a panorama that waves up and down, likely requiring fussy warping or cropping to correct. Avoid that; get it right in-camera!
A single-image portrait of a sunset sky with the waxing two-day-old crescent Moon amid colourful clouds over the prairie.
As the sky lit up, I also shot the crescent Moon above the sunset clouds and prairie scene. While the clouds made for a fine sunset, they did not clear off, thwarting my Milky Way plans this night. I headed back to Milk River, to travel farther west the next day.
From Writing-on-Stone I drove along scenic Highways 501 and 5 to Waterton Lakes National Park.
A nightscape scene under a twilight “blue-hour” sky, on the Red Rock Canyon Parkway in Waterton Lakes National Park, Alberta, looking west toward the sunset with the four-day-old crescent Moon.
After an initial cloudy night, I made use of the (mostly) clear night on June 10 to shoot twilight scenes with the now four-day-old crescent Moon in the evening sky. Here I wanted to play with another technique I had not used much before: focus stacking.
To keep exposures short (here to minimize the blurring effects of the constant wind at Waterton) you have to shoot at wide apertures (f/2 in this case). But that produces a very shallow depth of field, where only a small area of the image is in focus.
So I shot a series of six images, shifting the focus from near (for the foreground flowers) to far (for the mountains and sky). Photoshop has an Auto Blend function that will merge the images into one with everything in focus. I also shot separate images exposed for the bright sky, shooting a vertical panorama — dubbed a “vertorama” — moving the camera up from frame to frame.
I shot an additional short exposure just for the Moon, to prevent its disk from overexposing too much, as it did in the twilight sky images.
Twilight sky assembly and layers in Photoshop
So what looks like a simple snapshot of a twilight scene is actually a complex blend of focus-stacked ground images, panoramic sky images, and a single short image of the Moon replacing its otherwise overly bright disk. But the result better resembles what the eye saw, as single exposures often cannot record the range of brightness the eye can take in.

About an hour later, from the same location, I shot the other way, toward the Milky Way rising over Vimy Peak, but the sky still lit blue by moonlight. This, too, is a blend of focus-stacked ground and panorama sky images. But the camera was on a fixed tripod for exposures no longer than 15 seconds. So I didn’t use the tracker.
And here the longer exposures do pick up more (colours, fainter stars, and brighter ground detail) than was visible to the eye. Revealing more than the eye can see is the essence and attraction of astrophotography.
A vertical panorama of the moonlit spring sky with the Big Dipper and Arcturus over the jagged outline of Anderson Peak at the Red Rock Canyon area of Waterton Lakes National Park, Alberta.
Heading down the Red Rock Canyon Parkway, I set up the tracker rig for the darker sky, now that the Moon was nearly setting. I shot a vertical panorama, with two untracked ground segments and four tracked sky segments, to capture Arcturus and the Big Dipper over the iconic Anderson Peak.
Comparing without and with LENR – Lots of coloured specks without LENR! Tap to zoom up.
For all the images at Waterton and Writing-on-Stone I used the 45-megapixel Canon R5 camera, great for high resolution, but prone to noise, especially colourful thermal hot pixels. (See my review here.)
For all the long exposures I turned on Long Exposure Noise Reduction, a feature most cameras have. LENR forces the camera to take a “dark frame,” a second exposure of equal length, but with the shutter closed. The camera subtracts the dark frame (which records only the hot pixels) from the previous light frame. The final image takes twice as long to appear, but is much cleaner, as I show above. So a two-minute exposure requires four minutes to complete.
While there are clever ways to eliminate hot pixels later in processing (using Photoshop’s Dust and Scratches filter), doing so can blur details. I’ve long found that doing it “in-camera” always produces better results.
The Milky Way rising over the peak of Mt. Blakiston, in Waterton Lakes National Park, Alberta, Canada.
With the Moon now down, I turned the camera the other direction toward Mt. Blakiston, to capture the star clouds of the summer Milky Way rising behind the mountain, in an example of a “deepscape,” a nightscape with a telephoto lens. This is another technique I’ve not used very often, as the opportunities require good location planning and timing, transparent skies, and a tracker. Apps like ThePhotographersEphemeris coupled with TPE3D, and PlanItPro can help.
Deepscapes frame landscape fragments below some notable deep-sky objects and starfields, in this case a region with several “Messier objects” — nebulas and star clusters well-known to amateur astronomers.
This was a blend of one untracked and one tracked exposure, again on the Nomad. Taking more frames for stacking and noise reduction, while a common practice, was not practical here — at this focal length of 70mm the sky was moving enough that the mismatch between sky and ground would make blending tough to do.
And the reality is that today’s AI-trained noise reduction software (see my test report here) is so good, image stacking is not as essential as it once was.
For many of the Waterton images I used the Canon RF28-70mm lens, usually wide open at f/2. For the image below I used the RF15-35mm lens at its maximum aperture of f/2.8. (See my test report on these lenses here.)
The stars and clouds trail across the sky over Cameron Lake in Waterton Lakes National Park, Alberta, and Mt. Custer across the border in Glacier National Park in Montana.
On my final night in Waterton I drove the Akamina Parkway to Cameron Lake, located in extreme southwest Alberta on the borders with British Columbia and Montana. The glaciated peak to the south is Mt. Custer in Glacier National Park, Montana.
Again, I had hoped to get a deepscape of the photogenic starfields in Scorpius above Mt. Custer. But as is often the case at this site, clouds wafting over the Continental Divide defeated those plans. So Plan B was a set of long exposures of the clouds and stars trailing with the last light of the low Moon lighting parts of the scene. Chunks of ice still drift in the lake.
This is a blend of separate multi-minute exposures for the ground and sky, all at the slow ISO of just 100, and all untracked to purposely create the star trails, not avoid them.
So over a total of four nights at these wonderful World Heritage Sites, I was able to try out some new shooting techniques:
H-Alpha blending
Focus stacking
Deepscapes
As well as panoramas, both horizontal and vertical
Every nightscape outing is a learning process. And you have to be prepared to change plans as the clouds dictate. I didn’t get all the shots I had hoped to, but I still came away with images I was very pleased with.
It has been many years since we were treated to an aurora as widely seen as the show on May 10, 2024. Here’s my tale of the great display.
As the sky darkened around the world on May 10/11, 2024, sky watchers in both the northern and southern hemispheres were amazed to see the sky lit by the deep reds, greens and pinks of a massive display of aurora. For me, this was my first Kp8 to 9 show (to use one measure of aurora intensity) in more than 20 years, back in the film era!
Throughout the day, aurora chasers’ phones (mine included) had been beeping with alerts of the arrival of a major solar storm, with the usual indicators of auroral activity pinned to the top of the scale.
A NOAA satellite’s eye view of the ring of aurora May 10/11, showing it south of me in Alberta, and across the northern U.S. People in the southern U.S. saw it to their north.
As I show below, the graphic of the intensity of the band of aurora, the auroral oval, was lit up red and wide. This was a night we didn’t have to chase north to see the Northern Lights or aurora borealis — they were coming south to meet us (as I show above).
The Kp Index was reading 9 on SpaceWeatherLiveThe auroral oval was lit up red in the Ovation mapThe 3-hour predictions called for red and magenta alerts!
Observers in the southern hemisphere had the normally elusive aurora australis move much farther north than usual, bringing the Southern Lights even to tropical latitudes in Australia, South America and Africa.
The cause was a massive sunspot group on the Sun which had let off several intense solar flares.

The flares had in turn blown off parts of the Sun’s atmosphere, the corona, that anyone who saw the total eclipse a month earlier had admired so much. But a month later, the corona was being blown our way, in a series of Coronal Mass Ejections (CMEs), to collide with Earth.

As it happened I was scheduled to give a community talk in the nearby town early in the evening of May 10, on the topic of The Amazing Sky! Watching the indicators, I could more or less promise the audience that we would indeed see an amazing sky later that evening as it got dark.
Post talk, I hurried home to get the cameras ready, choosing to forgo more hurried driving out to a scenic site in southern Alberta, for the convenience of shooting from my rural backyard. As the sky darkened, the clouds were lit purple, and curtains of aurora appeared in the clear patches.

Something big was going on! This was promising to be the best show of Northern Lights I had seen from home in a year. (Spring 2023 had three great shows at monthly intervals, followed by an aurora drought for many months. See The Great April Aurora.)
A selfie at the start of the great aurora show of May 10, 2024.
I shot with four cameras (a Canon EOS R, Ra, R5 and R6) — two for time-lapses, one for real-time movies, and one for still images. I used the latter to take many multi-image panoramas, as they are often the best way to capture the wide extent of an aurora across the sky.
The arc of aurora in purple and white across the northern sky from home in Alberta at the start of the great display (about 11:30 p.m. MDT).
Early in the evening the arc of aurora wasn’t the usual green from oxygen, but shades of purple, pink, and even white, likely from sunlit nitrogen. The panorama above is looking north toward a strangely coloured arc of nitrogen (?) aurora.
Then after midnight a more normal curtain appeared suddenly, but toward the south, brightening and rising to engulf much of the southern sky and the sky overhead.
Looking south with the 15mm wide-angle lens.
It is at local midnight to 1 a.m. when substorms usually hit, as we are then looking straight down Earth’s magnetic tail, toward the rain of incoming aurora particles bombarding the Earth. During a substorm, the rain turns into a deluge — the intensity of the incoming electrons increases, sparking a sudden brightening of the aurora, making it dance all the more rapidly.
This is a 300° panorama of my home sky now filled with colourful curtains.
As the aurora explodes in brightness it often swirls up to the zenith (or more correctly, the magnetic zenith) to form one of the sky’s greatest sights, a coronal outburst. Rays and beams converge overhead to form a tunnel effect. It is jaw-dropping.
I’ve seen this many times from northern sites such as Churchill and Yellowknife, where the aurora often dances straight up. And from my latitude of 51° N in western Canada, the aurora does often come down to us.
But this night, people at latitudes where, at best, the aurora might be seen just as a glow on the horizon, saw it dance overhead in a corona show to rival the solar eclipse, and that other corona we saw on April 8!
This is a panorama of a substorm outburst creating an overhead corona with rays converging to the magnetic zenith (south of the true zenith), and amid clouds. The rays show a rich mix of oxygen greens and reds, as well as nitrogen blues blending to create purples. Some greens and reds are mixing to make yellows.
Yes, the long exposures of aurora photos (even those taken with phone cameras) show the colours better than your eye can see them (insensitive as our eyes are to colour in dim light). But this night portions of the arcs and rays were bright enough that greens and pinks were easily visible to the naked eye.
This is a single 9-second exposure of the peak of a bright outburst at 1 a.m. MDT. It was with the Laowa 7.5mm circular fish-eye lens at f/2 on the Canon R5 at ISO 800. It is one frame from a time-lapse sequence. A brief outburst of a substorm created an overhead corona with bright rays converging to the magnetic zenith (south of the true zenith).The corona shows a mix of oxygen greens and reds, as well as nitrogen blues blending to create purples. Some greens and reds mix to make yellows.
At its peak the show was changing rapidly enough, I couldn’t get to all the cameras to aim and frame them, especially the movie camera. The brightest outburst at 1 a.m. lasted just a minute — the time-lapse cameras caught it. The sequence below shows the view in 9-second exposures taken consecutively just 1 second apart.
This series shows a brief outburst of bright aurora at the magnetic zenith overhead. The time between these 7 consecutive 9-second exposures is only 1 second, so this bright outburst did not last long (little more than a minute). With the TTArtisan 7.5mm f/2 fish-eye lens on the Canon R5. Click or tap to enlarge to full screen.
Here’s another sequence of frames taken as part of a time-lapse sequence with the 11mm lens. It shows the change in the aurora over the 80 minutes or so that it was most active for me at my site.
The time between these 12 images is usually 8 minutes, though to include some interesting activity at a bright outburst, the interval is 5 minutes for three of the images around 1 a.m. Each is a 7- or 9-second exposure taken as part of a time-lapse sequence using the 11mm TTArtisan lens at f/2.8 on the Canon R at ISO 800 or 1600.
Shooting time-lapses with fish-eye lenses captures the show with a minimum of attention needed (except to adjust ISO or exposure times when the aurora brightens!). I could use the still camera (with the Laowa 15mm f/2 lens) to take individual shots, such as more selfies and home shots.
This is a single 6-second exposure with the Laowa 15mm lens at f/2 and Canon Ra at ISO 2000.This is a single 4-second exposure with the Laowa 15mm lens at f/2 and Canon Ra at ISO 1600. This is a single 8-second exposure with the Laowa 15mm lens at f/2 on the Canon Ra at ISO 800. Another camera taking a time-lapse is in the scene. I had four going this night.
As colourful as the aurora was at its best between midnight and 1:30 a.m., I think the most unique shots came after the show had subsided to appear just as faint rays across the north again, much as it had begun. To the eye it didn’t look like much, but even on the camera’s live screen I could see unusual colours.
I took more panoramas, to capture one of the most unusual auroral arcs I’ve even seen — a blue and magenta aurora across the north, similar to how the night started.
This a stitch of 11 segments, each 13-second exposures, with the Laowa 15mm lens at f/2 on the Canon Ra camera at ISO 800, and turned to portrait orientation. Processed in Camera Raw and stitched with PTGui.
The colours may be from nitrogen glowing, which tends to light up in blues and purples, especially when illuminated by sunlight at high altitudes. At 2 to 2:30 a.m. the Sun might have been illuminating the aurora at a height of 150 to 400 km, and far to the north.
I’d seen blue-topped green auroras before (and there’s a green aurora off to the west at left here). But this was the first time I’d seen an all-blue aurora, no doubt a product of the intense energy flowing in the upper atmosphere this night. And the season and my latitude.
The panorama is a spherical projection spanning 360º, and reaching to the zenith 90° high at centre. This a stitch of 20 segments, each 13-second exposures, with the Laowa 15mm lens at f/2 on the Canon Ra camera at ISO 800, and turned to portrait orientation. Processed in Camera Raw and stitched with PTGui.
The weirdest aurora was at 2:30 a.m., when in addition to the blue rays of nitrogen, an odd white and magenta patch appeared briefly to the south. What was that??
The lesson here? During a bright show do not go back to sleep when things seem to be dying down. Interesting phenomena can appear in the post-storm time, as we’ve learned with STEVE and other odd red arcs and green proton blobs that we aurora photographers have helped document.
I end with a finale music video, mostly made of the time-lapses I shot this night.
Enjoy!
Bring on more aurora shows as the Sun peaks in activity, perhaps this year. But the best shows often occur in the 2 or 3 years after solar max. So we have several more years to look forward to seeing the Lights dance in our skies.

I had always planned to drive to the April 8, 2024 total eclipse of the Sun. But to where? I ended up on the other side of the continent than originally planned.
It is not often the path of the Moon’s shadow crosses your home country, let alone continent. Only once before in recent years, on August 21, 2017, did the narrow shadow path pass near enough to my home in Alberta to allow me to drive to a total eclipse. They almost always require flying.
Packed and ready to hit the highway for a long eclipse trip.
Yes, while I could drive to the April 8, 2024 eclipse, it was going to demand a much longer drive than in 2017. But driving allowed me to take a carload of telescope and camera gear. So that was the plan.
My destination was San Antonio, Texas. That’s where I had made a hotel booking more than a year earlier. The weather prospects in Texas were forecast to be best (at least according to the long-term averages) of any locations along the path in the U.S. or Canada. (I did not want to drive into Mexico.)
Where I was going! Where I ended up going!
On March 30, with some trepidation, I set out down I-15 heading south. I got as far as Great Falls, Montana, my stop for night one. But it was to be a move in the wrong direction.
The forecast for Eclipse Day as of March 30. Blue is bad; white is good!
The various long-range weather models were all agreeing, even 10 days in advance, that Texas (covered in blue above) was looking poor for eclipse day. But eastern Canada looked good! That was the exact opposite of what had been expected.
So on Easter Sunday, I turned around and headed north, crossing back into Canada at a lonely border post in southwest Saskatchewan.
I proceeded east along the TransCanada, Highway 1. I decided against a route across the northern U.S. and around the southern end of Lake Michigan, to avoid severe weather forecast for the middle of the U.S.
One of my daily Facebook travelogue posts with a beer of the day.
Along the way I posted my beer-du-jour travel reports, as above from Day 8, that day from within the shadow path at last!
Our 1979 eclipse group in 1979.The 1979 eclipse site in 2024.The February 26, 1979 eclipse.
I also stopped at the only total eclipse site, of the 16 I had seen previously, I have ever been able to re-visit. On February 26, 1979 I and a small band of friends from Edmonton viewed the mid-winter eclipse (the last one visible from southern Canada) from a median road (Firdale Road as it is now called) on the TransCanada Highway near Carberry, Manitoba. I found the spot again, where I saw (and shot with my Questar telescope) my first total eclipse of the Sun.
However, a day after entering Ontario, the bad weather caught up with me, forcing an extra night north of Lake Superior while the only highway across the region, Highway 17, was cleared of snow and re-opened at Wawa, the usual cross-Canada choke point.
My new destination (after abandoning the site in the Texas Hill Country) was to be southern Ontario.
The weather prediction as of April 5.Southern Québec looking good!
However, as eclipse day approached and the weather predictions became more precise, it was apparent that Ontario would also be under some cloud. Southern Québec was looking better. So the Eastern Townships became my new Plan A site! I was running out of time!
Using the TPE app to check the Sun’s location once on site, the day before the eclipse.
I arrived on site in Québec with only a day to spare to check out the location I had found by exploring Google maps.
With the Sun lower in the mid-afternoon sky in Québec compared to the high-noon Sun in Texas, I decided to shoot a wide-angle scene of the eclipse over a lake, preferably with open water, not ice! That required a site with public parking on an eastern lakeshore.
The Photographer’s Ephemeris (TPE) app to check Sun angles.Zooming in with TPE app for my chosen Lac Brome site. .
The site I found, then checked out on April 7, was on Lac Brome. It proved ideal — except for the thin cloud that was now predicted to drift through during the eclipse.
Sure enough, that’s just what happened. The cloud detracted from the eclipse only in preventing long-exposure images recording the outermost streamers in the Sun’s atmosphere.
A wide-field view of the eclipse of the Sun, taking in the bright planets Jupiter (at top) and Venus (below) that were easily visible to the unaided eye during totality.
I could have sought out clearer skies by going even farther east, but I was in a crunch for time and hotel rooms! As it was I was able to get rooms everywhere I wanted and at normal “non-eclipse” rates!
A panorama of the lakeside parking area at Lac Brome prior to the eclipse. My RAV4 and camera array, pre-eclipse.I shot with 4 cameras at the car and one set up lakeside.
The Lac Brome site filled with cars during the day, with people from Québec and Ontario, but also from Alberta, and from Pennsylvania, Massachusetts and Maine – at least those were the homes of the folks I enjoyed meeting on eclipse day.
Everyone had a great time and had a superb eclipse experience.
The total eclipse of the Sun over the waters of Lac Brome, in the Eastern Townships of Quebec, Canada. The twilight colours come from sunlight from outside the shadow path.
The lunar shadow arrived from the southwest, from the direction of the Sun, appearing as a dark cloud racing toward us. At the end of the eclipse the sky brightened first in that same direction, as the trailing edge of the shadow shot up across the sky. The clouds helped make the shadow edge more visible.
A time-lapse of the arrival and departure of the lunar shadow, made of 1200 frames each 1 second apart.
I shot with five cameras, just as I had done in 2017, possible only because I drove.
The main rig was my faithful Astro-Physics Traveler, a 105mm refractor telescope the company owner designed for his personal use at the 1991 eclipse in Mexico.
My main eclipse rig, with a 60mm visual scope on the 105mm photo scope, on an equatorial tracking mount.
My Traveler, bought in 1992, has lived up to its name, having now been to six central solar eclipses: the annular eclipses of 1994 (Arizona) and 2023 (Utah), and the total eclipses of 1998 (Curaçao), 2012 (Queensland, Australia), 2017 (Idaho), and now 2024 in Québec, Canada. I paired it with the wonderful matching AP400 mount, which I had only just brought back with me the month before from Australia, where it had spent the last two decades.
All the gear worked great. Unlike six months earlier for the October 14, 2023 annular eclipse in Utah, this time I remembered all the cables needed to have the telescope mount track the Sun.
I did mess up on a couple of settings (such as not framing the 4K movie camera as I should have – in pre-eclipse excitement I just forgot to check my chart). But none of the errors were serious.
The eclipse in a blend of two exposures to display all the fiery pink prominences that were visible during totality around the lunar disk in one image, set against the bright inner corona of the Sun with the dark disk of the Moon in silhouette in front of the Sun.
Once started all my cameras, except for the one on the Traveler, ran unattended.
At this eclipse I was determined to get a good look at it through the small visual scope I had piggybacked onto the Traveler photo scope. While I had used a similar rig in 2017, I only thought to look through the visual scope 20 seconds before totality ended.
Not this year.
A telescopic close-up of the eclipsed Sun. Onto the central blend of images for totality I layered in single images of each of the diamond rings before and after totality. They are when the last or first burst of sunlight shines through lunar valleys. The first diamond ring is at top left, the last at bottom right, so time runs from left to right.
I got a great look at the eclipsed Sun, its corona structures, flaming pink prominences, and breakout of the red chromosphere layer just as totality ended. (You can’t easily see the chromosphere at the start of totality as it can be risky looking too soon through optics when the Sun’s blindingly bright photosphere is still in view.)
This is a composite showing the sequence of events surrounding totality, from just before totality (at upper left) to just after totality (at lower right), with totality in the middle. The contact images were taken 0.6 seconds apart.
And yet, as at all eclipses, I found the naked eye view the most compelling. The “black hole” Sun looked huge and unearthly. While I had binoculars handy, the same 12×36 image-stabilized binoculars I bring to most eclipses, I completely forgot to look though them, just as I forget at most eclipses!
This is a composite showing the complete sequence of the April 8, 2024 eclipse of the Sun, from first contact (at upper left) to last contact (at lower right), with totality at mid-eclipse in the middle.
I shot all the images with the Astro-Physics Traveler 105mm refractor at 630mm focal length and f/6, with the Canon R5 at ISO 100. The partial phases are 1/800 or 1/400 second exposures through a Kendrick/Baader solar filter.
Wanting to record the full sequence, I shot the partial phases until the bitter end. But post-eclipse, people came over and had a look through my scope (I think mine was the only telescope on site). We had a great time exchanging impressions. The hand-held phone camera photos people showed me looked fabulous!
I looked for fleeting shadow bands just before and after totality (I laid out a white sheet on the ground for the purpose) but saw none, a negative observation confirmed by a fellow eclipse chaser at the site.
Time-lapse movies of the second and third contact (start and end of totality) diamond rings, shot through the telescope with the Canon R5 in continuous burst mode for hundreds of frames each.
I did two live interviews for CBC Radio, for the Edmonton and Calgary stations, but not until after the eclipse ended. By the time I did those and finished packing away my carload of gear, it was 6:30 p.m., three hours after totality.
I was the last to leave the site, with fishermen now arriving for an evening’s catch.
I was in that shadow as the Space Station flew over. Astronauts saw the elliptical shadow moving over eastern Canada.
The passage of the lunar shadow across the continent, showing where the clouds were. I was under the wispy clouds at upper right in Québec.
I faced no traffic jams heading back to the hotel at Ste. Helen-de-Bagot. I processed and posted one eclipse image that night. And I revised the price (down to $2.99 U.S.) and description of my How to Photograph the Solar Eclipses ebook, as now only the big processing chapter is of any value, post-eclipse. It continues to sell.
This is the waxing crescent Moon on April 10, 2024, two days after it eclipsed the Sun, and with it above the bright planet Jupiter, with it also near Uranus. Below the solar system worlds is the faint Comet 12P/Pons-Brooks, visible here as a fuzzy star with a stubby tail..
On the long drive back to Alberta, with the pressure of having to make time now gone, I spent pleasant evenings stopping to see friends and family on the road home. So I didn’t start work on the complex blends and composite images I show here until I got home a week after the eclipse.
The happy eclipse chaser having bagged his game!
The 17-day-long drive was nearly 9,000 km over 100 hours behind the wheel. Was it worth it? Of course!
Would I do it again? It’s a moot question as none of the upcoming eclipses allows for a cross-continent drive. Except perhaps in July 2028 in Australia. But I suspect just heading inland a day or two over the Great Dividing Range will be enough to get away from winter coastal cloud in New South Wales. (Sydney is in the path, but so is a cottage I rented last month near Coonabarabran for my superb March stay under the southern skies!)
The next total eclipse of the Sun visible from anywhere in Canada will be August 22, 2044. I won’t have to drive anywhere, as it passes right over my house! But I will have to live that long to enjoy a eclipse from my own backyard.
I suspect this was my last chance to see – and drive to – a total eclipse in Canada.
Like all eclipses, seeing the October 14 annular eclipse of the Sun was not a certainty. As good luck and planning would have it, the sky and location could not have been better!
Annular eclipses of the Sun don’t present the spectacle of a total eclipse. Because the Moon is near its farthest point from Earth, its disk is not large enough to completely cover the Sun. At mid-eclipse, as I show below, a ring of sunlight (dubbed a “ring of fire”) remains, still too bright to view without a solar filter.
The October 14, 2023 annular solar eclipse, in a single image captured at mid-eclipse, at 10:29 am MDT at the Ruby’s Inn Overlook on the rim of Bryce Canyon, Utah, a site well south of the centreline, with 3m03s of annularity.
While lacking the jaw-dropping beauty of a total, annular eclipses are rare and unique enough that every ardent skywatcher should make a point of seeing one.
Prior to October 14, I had seen only one, on May 10, 1994, from southeast Arizona, an event I captured on film of course back then.
My 1994 annular eclipse setup in ArizonaMy 2023 annular eclipse setup in Utah
A sunset annular on June 10, 2002 that I traveled to Puerto Vallarta, Mexico to see was mostly clouded out. The annular of May 20, 2012 traced a similar path across the U.S. Southwest as the 2023 eclipse. But work commitments at the science centre in Calgary kept me home for that one. A sunrise annular on June 10, 2021 in Northwestern Ontario was essentially out of reach due to COVID travel restrictions.
With no other annular eclipses within easy reach in North America until 2039 and 2046, this was my next, and perhaps last, opportunity to see one, unless I chose to travel the world.
Eclipse site and pathSite close upEclipse details at my final site
I had planned for several months to watch the annular eclipse from southern Utah, ideally from Bryce Canyon National Park, shown above. (Clicking on the images brings them up full screen.) I booked accommodations in January 2023, finding even then that popular hotels in the area were already sold out.
The final spot for the wide-angle composite shown below. The camera had to be next to that very fence post to frame the scene well.
The attraction was the landscape below the morning Sun, for a planned composite image of the eclipse over the hoodoos of Bryce. However, I had learned weeks earlier that traffic was going to be restricted to just park shuttle buses on eclipse day. Should Plan A not work out then Plan B was Kodachrome Basin, a state park nearby, which a park employee assured me would be open to cars well before sunrise on eclipse day.
Seen on I-15 past Salt Lake City. Eclipse ahead!
So I made my plans to drive south, taking with me a carload of telescope and camera gear, an array I would never be able to take to an overseas eclipse. The centrepiece was my venerable Astro-Physics Traveler 105mm (4-inch) refractor, a telescope created for the 1991 total eclipse in Mexico. Since I bought mine in 1992 I’ve used it for five central solar eclipses, including now two annulars. It’s in the 1994 and 2023 site images above.
A week before the eclipse (as above at left), the weather prospects for the entire southwest looked poor. It was to be clouds everywhere. I even considered Plan S – Stay Home! And watch the 60% partial eclipse from Alberta where skies were to be clear.
But undaunted, six days before the eclipse, I headed south on Interstate 15, checking the weather each day, and seeking out Plan C sites in New Mexico or Texas south of the projected mass of clouds. I checked where accommodation could be had at the last minute.
At my stop in Richfield, Utah, four days before the eclipse, I had a crossroads turning point: either continue south to Bryce down US-89 (above), or head east on I-70, then south into New Mexico or Texas, with enough time to get there if needed.
But by now the weather prospects were turning around. By three days out, and with the forecasts now much more reliable, it looked like southern Utah would be in the clear. I continued with my original plan to Bryce. But where exactly?
TPE site overview with anglesTPE 3D showing Sun pathGoogle Earth 3D
I had looked at possible sites on Google Earth and with the Sun-angle planning apps I use (such as The Photographer’s Ephemeris, or TPE) and found one just outside the Park that I hoped would be accessible to drive into.
Upon arriving in the area three days early, the first priority was to inspect the site in person. It looked perfect! Almost too good to be true!
A panorama of the Ruby’s Inn site with the eclipse in progress. My wide-angle camera is at left by that fencepost.
The site, known as the Ruby’s Inn Overlook, provided a great view toward the eclipse with a stunning landscape below, including a river! (Well, it was actually an irrigation channel called the Tropic Ditch.) And I could park right next to my wide-angle landscape camera, to keep an eye on it over the five hours of shooting, while setting up the scope gear next to my car.
I stayed at the Bryce View Lodge on eclipse eve, a hotel just a few hundred metres from the site. So no long pre-dawn drive on eclipse morn. However, the gated site was not going to be open until 7 a.m. on eclipse day. And admission was $20 per car, a cash donation to the Bryce Canyon City school sports teams. Fine!
As it turned out, by the time I got on site and setup the priority wide-angle camera for the base-image sunrise shots at 7:30 a.m., the sky was too bright to polar align the telescope mount on Polaris, for accurate tracking of the Sun across the sky.
It turned out that was the least of my concerns.
My three eclipse cameras: the wide-angle, the one on the 105mm refractor telescope (with a smaller 60mm scope on top for visual views with a Herschel Solar Wedge), and one with a 100-400mm lens on the tripod.
As I unpacked the carload of scope gear at 8 a.m. I realized I had forgotten a crucial cable to connect the mount to the drive electronics. So the mount was not going to be able to track anyway!
So much for my plans for a time-lapse through the scope. I had to manually centre the Sun every minute or so. I took lots of photos, but gave up on any effort to take them at a regular cadence. But I had enough images for the singles and composites shown here.
This is a composite of the October 14, 2023 annular solar eclipse with a sequence of six images showing the Moon advancing across a sunspot, the largest one visible on the Sun that day. The images are placed for a photogenic spacing, with time running forward from lower left to upper right, to reflect the Sun’s motion up across the morning sky.
Of course, once I got home the first thing I did was look downstairs in my scope room. Sure enough there was the cable, mixed up with the similar electronics from another mount I have from the same company, as I had been testing both prior to the eclipse. So much for my checklists! They’re only good if they list every critical bit, and if you use them.
So that was one big user error.
You don’t want to see this at an eclipse!
The other was a camera error, in fact Error70! I had set my main telescope camera to take rapid bursts of images (at up to 20 frames per second) at the crucial second and third contacts when annularity began and ended. With the Moon’s rough limb tangent to the inside edge of the Sun, you see beads of light rapidly form and disappear at the contacts.
This is a composite of the October 14, 2023 annular solar eclipse at second contact. It illustrates the irregular edge of the Moon breaking up the rim of sunlight as the dark disk of the Moon became tangent to the inner edge of the Sun at second contact at the start of annularity. 15 exposures taken over 20 seconds at second contact are combined with a single exposure taken about 1.5 minutes later at mid-annularity.
The camera worked great at second contact, shooting 344 frames over 20 seconds. A composite of 15 of those frames is above, layered to exaggerate the rough lunar limb and its mountain peaks. A time-lapse from those frames is below.
A time-lapse of second contact from 344 frames over ~20 seconds.
And it appeared to be working at third contact three minutes later. Until I looked down and saw the dreaded error message. In checking the camera later, none of the third contact images had recorded to either memory card.
It is a known but intermittent bug in Canon firmware that can happen when the camera is not connected to a Canon lens (it was on a telescope it cannot communicate with). I saw the error once in testing. And I had a hard time reproducing it to take the screen shot above once I got home. But if something can go wrong …!
This is a portrait of the October 14, 2023 annular eclipse of the Sun, captured in a sequence of images taken from the rim of Bryce Canyon, Utah, from sunrise until nearly the end of the eclipse before noon local time. This is a composite blend of unfiltered exposures taken at sunrise for the landscape lit by the rising Sun, and for the dawn sky. Onto the base panorama of the ground and sky I layered in 66 filtered images of the Sun, as it rose into the morning sky, and with the Moon moving across its disk over nearly 3 hours, reaching mid-eclipse at about 10:29 local MDT at upper right. It then appears as a ring, or annulus of light for one frame.
Despite the errors both human and machine, I count eclipse day as successful, considering a week earlier prospects had looked so poor. As it was, apart from some thin but inconsequential cloud that drifted through before mid-eclipse, the sky was perfect.
As was the site. I enabled me to get the main shot I was after, the wide-angle composite, above. It’s a winner! And it accurately depicts the size of the Sun and its motion across the sky, albeit set into a twilight sky taken at sunrise.
As it had been 29 years since my last annular, I wasn’t sure what to expect. But the darkening of the sky and eerie level of sunlight, despite a blazing Sun in the day sky, were impressive. The morning just looked strange! It was a taste of the total to come.
Venus at its widest angle west of the Sun was easy to spot in the deep blue sky. I regret not thinking to shoot even a phone camera image of that sight.
Projecting the solar crescents with a made-on-the-spot pinhole projection sign.
I had pleasant chats with other folks at the site, and enjoyed showing them telescopic views though the smaller visual scope I had piggybacked on the main scope, one that was just for looking through. Plus folks shot phone pix of my camera screen.
The October 14, 2023 annular solar eclipse, in a single image captured at second contact with the Moon tangent to the inside limb of the Sun, at 10:27 am MDT at the site I used.
But at the critical contacts, I was glued to that visual scope for the amazing sight of the horns of the crescent Sun rapidly wrapping around the Moon at second contact, then unwrapping at third contact.
The October 14, 2023 annular solar eclipse, in a series of images captured at second contact with the Moon tangent to the inside limb of the Sun, at 10:27 am MDT at the site I used. The 7 frames here were selected from a set of 344 shot in high-speed continuous mode at 20 frames per second.
The breakup of the rim of sunlight into beads of light along the cratered and mountainous edge of the Moon was also impressive. I was not at the optimum site for seeing those beads, as the landscape dictated my choice of location. But those that I saw at each of the internal contacts were a fine bonus to a memorable morning.
This is a composite that records the sequence around mid-eclipse of the October 14, 2023 annular eclipse of the Sun. This is a blend of 8 exposures each taken 2.25 minutes apart, about the minimum time to keep the disks separate and avoid them overlapping.
A third camera shooting a sequence with an untracked 400mm telephoto lens worked well. I used a subset of its images to create a still-image composite (above) and the full set for a time-lapse (below), with the position and motion of the Sun authentic, produced by the natural east-to-west motion of the sky. But against that you see the Moon’s orbital motion moving its dark disk down across the disk of the Sun.
A time-lapse from 300 frames taken at 4-second intervals with the sky’s motion carrying the Sun across the frame.
As soon as annularity ended, everyone else started to pack up and leave. For them the show was over. Understandably. On many total eclipse tours I’ve been on we’ve been on the road back to the hotel after totality and the requisite happy group shot.
Eclipse success! The trophy shot after everyone else had left.
But at this eclipse my shooting plan dictated that I stick it out. By the end of the eclipse I was the last one standing, alone to enjoy last contact and then lunch, killing time for any road congestion to diminish, as I had to head to another motel for the post-eclipse night, in nearby Panguitch.
I had a celebratory dinner and Moab-brewed beer that night at Cowboy’s, the best restaurant in Panguitch, sporting my Annular 2023 eclipse hat!
But the next day I started the drive north again, for the three-day trek back up I-15 to the border, then home.
Priority one upon getting home was to finish processing images, and to include them in a revised version of my ebook How to Photograph the Solar Eclipses. It is linked to above and here on the title. Images of some sample pages from the revised edition are in the slide show below.
Post-annular, the book’s title remains the same, but I revised the pages in Chapter 4 on planning for the 2023 eclipse with pages on “lessons learned!” And there were several!
I expanded Chapter 11 on processing to include tutorials on assembling annular eclipse composites, now that I actually have some!
Such as the composite of first- to last-contact telescopic close-ups below.
This is a composite of the various stages of the entire October 14, 2023 annular solar eclipse, from start (lower left) to end (upper right), with mid-eclipse at centre. So time runs forward from left to right, with the Suns positioned to reflect the approximate motion of the Sun in the morning sky when this eclipse occured at my site, with it rising higher through the progress of the eclipse. North is up in this image.
The new version of my ebook is 20 pages larger than the pre-annular edition.
An email has gone out from eJunkie to all buyers of the earlier-edition PDF to alert them to the new version, and with a download link. Apple Books readers should get a notice when they open the book on their Mac or iPad in the Books app that a new version is available.
I suspect that will be the last revision of my ebook before the big event – the total eclipse of the Sun on April 8, 2024.
Here’s wishing us all clear skies for that one! That eclipse will indeed require a drive to Texas. This time I’ll remember that damned cable!
In mid-October 2022 I enjoyed a rare run of five clear and mild nights in the Rocky Mountains for shooting nightscapes of the stars. Here’s a portfolio … and a behind-the-scenes look at its making.
Getting two perfectly clear nights in a row is unusual in the mountains. Being treated to five is a rare treat. Indeed, had I started my shooting run earlier in the week I could have enjoyed even more of the string of cloudless nights in October, though under a full Moon. But five was wonderful, allowing me to capture some of the scenes that had been on my shot list for the last few years.
Here is a portfolio of the results, from five marvelous nights in Banff and Jasper National Parks, in Alberta, Canada.
For the photographers, I also provide some behind-the-scenes looks at the planning and shooting techniques, and of my processing steps.
Night One — Peyto Lake, Banff National Park
Peyto Lake, named for pioneer settler and trail guide Bill Peyto who had a cabin by the lakeshore, is one of several iconic mountain lakes in Banff. Every tour bus heading along the Icefields Parkway between Banff and Jasper stops here. By day is it packed. By night I had the newly constructed viewpoint all to myself.
The stars of Ursa Major, the Great Bear, over the waters of Peyto Lake, Banff, in deep twilight. This is a stack of 6 x 30-second exposures for the ground and a single untracked 30-second exposure for the sky, all at f/2.8 with the Canon RF 15-35mm lens at 15mm, and Canon R5 at ISO 800.
I shot the classic view north in deep twilight, with the stars of Ursa Major and the Big Dipper low over the lake, as they are in autumn. A show of Northern Lights would have been ideal, but I was happy to settle for just the stars.
This is a blend of two panoramas: the first of the sky taken at or just before moonrise with the camera on a star tracker to keep the stars pinpoint, and the second taken for the ground about 20 minutes later with the tracker off, when the Moon was up high enough to light the peaks. Both pans were with the Canon RF15-35mm lens at 15mm and f/2.8, and Canon R5 at ISO 1600, with the sky pan being 7 segments for 1 minute each, and the untracked ground panorama being the same 7 segments for 2 minutes each.
The night was perfect, not just for the clarity of the sky but also the timing. The Moon was just past full, so was rising in late evening, leaving a window of time between the end of twilight and moonrise when the sky would be dark enough to capture the Milky Way. Then shortly after, the Moon would come up, lighting the peaks with golden moonlight — alpenglow, but from the Moon not Sun.
The above is blend of two panoramas, each of seven segments, the first for the sky taken when the sky was dark, using a star tracker to keep the stars pinpoints. The second for the ground I shot a few minutes later at moonrise with no tracking, to keep the ground sharp. I show below how I blended the two elements.
The Photographer’s Ephemeris
TPE 3D
To plan such shots I use the apps The Photographer’s Ephemeris (TPE) and its companion app TPE 3D. The screen shot above at left shows the scene in map view for the night in question, with the Big Dipper indicated north over the lake and the line of dots for the Milky Way showing it to the southwest over Peyto Glacier. Tap or click on the images for full-screen versions.
Switch to TPE 3D and its view at right above simulates the scene you’ll actually see, with the Milky Way over the mountain skyline just as it really appeared. The app even faithfully replicates the lighting on the peaks from the rising Moon. It is an amazing planning tool.
This is a blend of 5 x 20-second exposures stacked for the ground to smooth noise, and a single 20-second exposure for the sky, all with the Canon RF15-35mm lens at f/2.8 and Canon R5 at ISO 1600. All were untracked camera-on-tripod shots.
On the drive back from Peyto Lake to Saskatchewan River Crossing I stopped at another iconic spot, the roadside viewpoint for Mt. Cephren at Waterfowl Lakes. By this time, the Moon was well up and fully illuminating the peak and the sky, but still leaving the foreground dark. The sky is blue as it is by day because it is lit by moonlight, which is just sunlight reflecting off a perfectly neutral grey rock, the Moon!
This is from a set of untracked camera-on-tripod shots using short 30-second exposures.
Night Two — Pyramid Lake, Jasper National Park
By the next night I was up in Jasper, a destination I had been trying to revisit for some time. But poor weather prospects and forest fire smoke had kept me away in recent years.
The days and nights I was there coincided with the first weekend of the annual Jasper Dark Sky Festival. I attended one of the events, the very enjoyable Aurora Chaser’s Retreat, with talks and presentations by some well-known chasers of the Northern Lights. Attendees had come from around North America.
This is a blend of: a stack of 4 x 1-minute tracked exposures for the sky at ISO 1600 plus a stack of 7 x 2-minute untracked exposures at ISO 800 for the ground, plus an additional single 1-minute tracked exposure for the reflected stars and the foreground water. All were with the Canon RF15-35mm lens at 15mm and f/2.8 and Canon R5.
On my first night in Jasper I headed up to Pyramid Lake, a favorite local spot for stargazing and night sky photography, particularly from the little island connected to the “mainland” by a wooden boardwalk. Lots of people were there quietly enjoying the night. I shared one campfire spot with several other photographers also shooting the Milky Way over the calm lake before moonrise.
This is a blend of: a stack of 4 x 1-minute tracked exposures for the sky at ISO 1600 plus a stack of 6 x 3-minute untracked exposures at ISO 800 for the ground, all with the Canon RF15-35mm lens at 20mm and f/2.8 and Canon R5. The tracker was the Star Adventurer Mini.
A little later I moved to the north end of Pyramid Island for the view of the Big Dipper over Pyramid Mountain, now fully lit by the rising waning Moon, and with some aspens still in their autumn colours. A bright meteor added to the scene.
Night Three — Athabasca River Viewpoint, Jasper National Park
For my second night in Jasper, I ventured back down the Icefields Parkway to the “Goats and Glaciers” viewpoint overlooking the Athabasca River and the peaks of the Continental Divide.
This is a blend of three 3-section panoramas: the first taken with a Star Adventurer Mini for 3 x 2-minute tracked exposures for the sky at ISO 800; the second immediately afterward with the tracker off for 3 x 3-minutes at ISO 800 for the ground; and the third taken about an hour later as the Moon rose, lighting the peaks with warm light, for 3 x 2.5-minutes at ISO 1600. All with the Canon RF15-35mm lens at f/2.8 and 15mm and Canon R5,
As I did at Peyto Lake, I shot a panorama (this one in three sections) for the sky before moonrise with a tracker. I then immediately shot another three-section panorama, now untracked, for the ground while it was still lit just by starlight under a dark sky. I then waited an hour for moonrise and shot a third panorama to add in the golden alpenglow on the peaks. So this is a time-blend, bending reality a bit. See my comments below!
Night Four — Edith Lake, Jasper National Park
With a long drive back to Banff ahead of me the next day, for my last night in Jasper I stayed close to town for shots from the popular Edith Lake, just up the road from the posh Jasper Park Lodge. Unlike at Pyramid Lake, I had the lakeshore to myself.
This is a panorama of four segments, each 30 seconds untracked with the Canon RF15-35mm lens at 15mm and f/2.8 and Canon R5 at ISO 1000.
This would be a fabulous place to catch the Northern Lights, but none were out this night. Instead, I was content to shoot scenes of the northern stars over the calm lake and Pyramid Mountain.
This is a blend of a single tracked 2-minute exposure for the sky and water with the reflected stars, with a single untracked 4-minute exposure for the rest of the ground, both at f/2.8 with the Canon RF15-35mm lens at 17mm and Canon R5 at ISO 800.
This is a blend of a single tracked 2-minute exposure for the sky and water with the reflected stars, with a stack of two untracked 3-minute exposure for the rest of the ground, both at f/2.8 with the Canon RF15-35mm lens at 17mm and Canon R5 at ISO 1600. I shot this October 16, 2022.
The Moon was now coming up late, so the shots above are both in darkness with only starlight providing the illumination. Well, and also some annoying light pollution from town utility sites off the highway. Jasper is a Dark Sky Preserve, but a lot of the town’s street and utility lighting remains unshielded.
Night Five — Lake Louise, Banff National Park
On my last night I was at Lake Louise, as the placement of the Milky Way would be perfect.
This is a blend of two sets of exposures: – a stack of two untracked 2-minute exposures for the ground at ISO 800 – a stack of four tracked 1-minute exposures for the sky at ISO 1600 All with the Canon RF15-35mm lens at f/2.8 and 20mm and Canon R5, and with the camera and tripod not moving between image sets.
There’s no more famous view than this one, with Victoria Glacier at the end of the blue-green glacial lake. Again, by day the site is thronged with people and the parking lot full by early morning.
By night, there were just a handful of other photographers on the lakeshore, and the parking lot was nearly empty. I could park right by the walkway up to the lake.
The Photographer’s Ephemeris
TPE 3D
Again, TPE and TPE 3D told me when the Milky Way would be well-positioned over the lake and glacier, so I could complete the untracked ground shots first, to be ready to shoot the tracked sky segments by the time the Milky Way had turned into place over the glacier.
This is a blend of three vertical panoramas: the first is a set of three untracked 2-minute exposures for the ground at ISO 800 with the camera moved up by 15° from segment to segment; the second shot immediately afterward is made of 7 x 1-minute tracked exposures at ISO 1600 for the sky, also moved 15° vertically from segment to segment; elements of a third 3-section panorama taken about 90 minutes earlier during “blue hour” were blended in at a low level to provide better lighting on the distant peaks. All with the Canon RF15-35mm lens at f/2.8 and 20mm and Canon R5.
This image is also a panorama but a vertical one, made primarily of three untracked segments for the ground and seven tracked segments for the sky, panning up from the horizon to past the zenith overhead, taking in most of the summer and autumn Milky Way from Serpens up to Cassiopeia.
Nightscape Gear
As readers always want to know what gear I used, I shot all images on all nights with the 45-megapixel Canon R5 camera and Canon RF15-35mm lens, with exposures of typically 1 to 3 minutes each at ISOs of 800 to 1600. I had other cameras and lenses with me but never used them.
Star Adventurer Mini tracker with Alyn Wallace V-Plate and AcraTech Panorama Head
For a tracker for such images, I used the Sky-Watcher Star Adventurer Mini, a compact and lightweight unit that is easy to pack and carry to shooting sites. See my review of it here at AstroGearToday.
I use the Mini with a V-Plate designed by nightscape photographer Alyn Wallace and sold by Move-Shoot-Move. It is an essential aid to taking tracked panoramas, as it allows me to turn the camera horizontally manually from one pan segment to the next while the camera is tracking the stars. It’s easy to switch the tracker on (for the sky) and off (for the ground). The Mini tracks quite accurately and reliably. Turn it on and you can be sure it is tracking.
For those who are interested, here’s a look at how I processed and assembled the images, using the Peyto Lake panorama as an example. This is not a thorough tutorial, but shows the main steps involved. Tap or click on an image to download a full-size version.
I first develop all the raw files (seven here) in Adobe Camera Raw, applying identical settings to make them look best for what they are going to contribute to the final blend, in this case, for the tracked sky with pinpoint stars and the Milky Way.
Camera Raw (as does Adobe’s Lightroom) has an excellent Merge to Panorama function which usually works very well on such scenes. This shows the stitched sky panorama, created with one click.
I develop and stitch the untracked ground segments to look their best for revealing details in the landscape, overexposing the sky in the process. Stars are also trailed, from the long exposures needed for the dark ground. No matter – these will be masked out.
This shows the stack of images now in Adobe Photoshop, but here revealing just the layer for the sky panorama and its associated adjustment layers to further tweak color and contrast. I often add noise reduction as a non-destructive “smart filter” applied to the “smart object” image layer. See my review of noise reduction programs here.
This shows just the ground panorama layer, again with some adjustment and retouching layers dedicated to this portion of the image.
The sky has to be masked out of the ground panorama, to reveal the sky below. The Select Sky command in Photoshop usually works well, or I just use the Quick Selection tool and then Select and Mask to refine the edge. That method can be more accurate.
Aligning the two panoramas requires manually nudging the untracked ground, up in this case, to hide the blurred and dark horizon from the tracked sky panorama. Yes, we move the earth! The sky usually also requires some re-touching to clone out blurred horizon bits sticking up. Dealing with trees can be a bit messy!
The result is the scene above with both panorama layers and the masks turned on. While this now looks almost complete, we’re not done yet.
Local adjustments like Dodge and Burn (using a neutral grey layer with a Soft Light blend mode) and some luminosity masks tweak the brightness of portions of the scene for subtle improvements, to emphasize some areas while darkening others. It’s what film photographers did in the darkroom by waving physical dodging and burning tools under the enlarger.
I add finishing touches with some effect plug-ins: Radiant Photo added some pop to the ground, while Luminar Neo added a soft “Orton glow” effect to the sky and slightly to the ground.
All the adjustments, filters, and effects are non-destructive so they can be re-adjusted later, when upon further inspection with fresh eyes I realize something needs work.
Was It Photoshopped?
I hope my look behind the curtains was of interest. While these types of nightscapes taken with a tracker, and especially multi-segment panoramas, do produce dramatic images, they do require a lot of processing at the computer.
Was it “photoshopped?” Yes. Was it faked? No. The sky really was there over the scene you see in the image. However, the long exposures of the camera do reveal more details than the eye alone can see at night — that is the essence of astrophotography.
My one concession to warping reality is in the time-blending — the merging of panoramas taken 30 minutes to an hour apart. I’ll admit that does push my limits for preferring to record real scenes, and not fabricate them (i.e. “photoshop” them in common parlance).
But at this shoot on these marvelous nights, making use of the perfectly timed moonrises was hard to resist!
On December 21 we have a chance to see and shoot a celestial event that no one has seen since the year 1226.
As Jupiter and Saturn each orbit the Sun, Jupiter catches up to slower moving Saturn and passes it every 20 years. For a few days the two giant planets appear close together in our sky. The last time this happened was in 2000, but with the planets too close to the Sun to see.
Back on February 18, 1961 the two planets appeared within 14 arc minutes or 0.23° (degrees) of each other low in the dawn sky.
But on December 21 they will pass each other only 6 arc minutes apart. To find a conjunction that close and visible in a darkened sky you have to go all the way back to March 5, 1226 when Jupiter passed only 3 arc minutes above Saturn at dawn. Thus the media headlines of a “Christmas Star” no one has seen for 800 years!
Photographing the conjunction will be a challenge precisely because the planets will be so close to each other. Here are several methods I can suggest, in order of increasing complexity and demands for specialized gear.
Easy — Shooting Nightscapes with Wide Lenses
This shows the field of view of various lenses on full-frame cameras (red outlines) and a 200mm lens with 1.4x tele-extender on a cropped frame camera (blue outline). The date is December 17 when the waxing crescent Moon also appears near the planet pair for a bonus element in a nightscape image.
Conjunctions of planets in the dusk or dawn twilight are usually easy to capture. Use a wide-angle (24mm) to short telephoto (85mm) lens to frame the scene and exposures of no more than a few seconds at ISO 200 to 400 with the lens at f/2.8 to f/4.
The sky and horizon might be bright enough to allow a camera’s autoexposure and autofocus systems to work.
Indeed, in the evenings leading up to and following the closest approach date of December 21 that’s a good method to use. Capture the planet pair over a scenic landscape or urban skyline to place them in context.
For most locations the planets will appear no higher than about 15° to 20° above the southwestern horizon as it gets dark enough to see and shoot them, at about 5 p.m. local time. A 50mm lens on a full-frame camera (or a 35mm lens on a cropped frame camera) will frame the scene well.
This was Jupiter and Saturn on December 3, 2020 from the Elbow Falls area on the Elbow River in the Kananaskis Country southwest of Calgary. This is a blend of 4 untracked images for the dark ground, stacked to smooth noise, for 30 seconds each, and one untracked image for the bright sky for 15 seconds to preserve colours and highlights, all with the 24mm Sigma lens and Canon EOS Ra at ISO 200.
NIGHTSCAPE TIP — Use planetarium software such as Stellarium (free), SkySafari, or StarryNight (what I used here) to simulate the framing with your lens and camera. Use that software to determine where the planets will be in azimuth, then use a photo planning app such as PhotoPills or The Photographer’s Ephemeris to plan where to be to place the planets over the scene you want at that azimuth (they’ll be at about 220° to 230° — in the southwest — for northern latitude sites).
This was Jupiter and Saturn on December 10, 2020 from Red Deer River valley, north of Drumheller, Alberta. This is a blend of 4 images for the dark ground, stacked to smooth noise, for 20 seconds each at f/5.6, and a single image for the sky for 5 seconds at f/2.8, all with the 35mm Canon lens and Canon EOS Ra at ISO 400. All untracked.
Harder — Shooting With Longer Lenses
The planet pair will sink lower and closer to the horizon, to set about 7:00 to 7:30 p.m. local time each night.
As the sky darkens and the planet altitude decreases you can switch to ever-longer lenses to zoom in on the scene and still frame the planets above a carefully-chosen horizon, assuming you have very clear skies free of haze and cloud.
For example, by 6 p.m. they will be low enough to allow a 135mm telephoto to frame the planets and still have the horizon in the frame. Using a longer lens has the benefit or resolving the two planets better, showing them as two distinct objects, which will become more of a challenge the closer you are to December 21.
On December 21 wide-angle and even short telephoto lenses will likely show the two planets as an unresolved point of light, no brighter than Jupiter on its own.
On closest approach day the planets will be so close that using a wide-angle or even a normal lens might only show them as an unresolved blob of light. You’ll need more focal length to split the planets well into two objects.
However, using longer focal lengths introduces a challenge — the motion of the sky will cause the planets to trail during long exposures, turning them from points into streaks. That trailing will get more noticeable more quickly the longer the lens you use.
A rule-of-thumb says the longest exposure you can employ before trailing becomes apparent is 500 / the focal length of the lens. So for a 200mm lens, maximum exposure is 500 / 200 = 2.5 seconds.
To be conservative, a “300 Rule” might be better, restricting exposures with a 200mm telephoto to 300 / 200 = 1.5 seconds. Now, 1.5 seconds might be long enough for the scene, especially if you use a fast lens wide open at f/2.8 or f/2 and a faster ISO such as 400 or 800.
This shows the motion of Jupiter relative to Saturn from December 17 to 25, with the outer frame representing the field of view of a 200mm lens and 1.4x tele-extender on a cropped frame camera. The smaller frame shows the field of a telescope with an effective focal length of 1,200mm.
TELEPHOTO TIP — Be sure to focus carefully using Live View to manually focus on a magnified image of the planets. And refocus through an evening of shooting. While people fuss about getting the one “correct” exposure, it is poor focus that ruins more astrophotos.
Even More Demanding — Tracking Longer Lenses
This one popular sky tracker, the iOptron SkyGuider Pro, here with a telephoto lens. It and other trackers such as the Sky-Watcher Star Adventurer seen in the opening image, can be used with lenses and telescopes up to about 300mm focal length, if they are balanced well. Even longer lenses might work for the short exposures needed for the planets, but vibration and wind can blur images.
However, longer exposures might be needed later in the evening when the sky is darker, to set the planets into a starry background. After December 17 we will have a waxing Moon in the evening sky to light the sky and foreground, so the sky will not be dark, even from a rural site.
Even so, to ensure untrailed images with long telephotos — and certainly with telescopes — you will need to employ a sky tracker, a device to automatically turn the camera to follow the sky. If you don’t have one, it’s probably too late to get one and learn how to use it! But if you have one, here’s a great opportunity to put it to use.
Polar align it (you’ll have to wait for it to get dark enough to see the North Star) and then use it to take telephoto close-up images of the planets with exposure times that can now be as long as you like, though they likely won’t need to be more than 10 to 20 seconds.
You can now also use a slower ISO speed for less noise.
TRACKER TIP — Use a telephoto to frame just the planets, or include some foreground content such as a hilltop, if it can be made to fit in the frame. Keep in mind that the foreground will now blur from the tracking, which might not be an issue. If it is, take exposures of the foreground with the tracker motor off, to blend in later in processing.
The Most Difficult Method — Using a Telescope
An alt-azimuth mounted GoTo scope like this Celestron SE6 can work for short exposures of the planets, provided it is aligned and is tracking properly. Good focus will be critical.
Capturing the rare sight of the planets as two distinct disks (not just dots of light) accompanied by their moons, all together in the same frame, is possible anytime between now and the end of the year.
But … resolving the disks of the planets takes focal length — a lot of focal length! And that means using a telescope on a mount that can track the stars.
While a sky tracker might work, they are not designed to handle long and heavy lenses and telescopes. You’d need a telescope on a solid mount, though it could be a “GoTo” telescope on an alt-azimuth mount. Such a mount, while normally not suited for long-exposure deep-sky imaging, will be fine for the short exposures needed for the planets.
You will need to attach your camera to the telescope using a camera adapter, so the scope becomes the lens. If you have never done this, to shoot closeups of the Moon for example, and don’t have the right adapters and T-rings, then this isn’t the time to learn how to do it.
A simulation of the view with a 1,200mm focal length telescope on December 21. Even with such a focal length the planet disks still appear small.
TELESCOPE TIP — As an alternative, it might be possible to shoot the planets using a phone camera clamped to the low-power eyepiece of a telescope, but focusing and setting the exposure can be tough. It might not be worth the fuss in the brief time you have in twilight, perhaps on the one clear night you get! Just use your telescope to look and enjoy the view!
But if you have experience shooting the Moon through your telescope with your DSLR or mirrorless camera, then you should be all set, as the gear and techniques to shoot the planets are the same.
This is the setup I might use for a portable rig best for a last-minute chase to clear skies. It’s a Sky-Watcher EQM-35 mount with a 105mm apo refractor (the long-discontinued Astro-Physics Traveler), and here with a 2x Barlow to double the effective focal length to 1,200mm.
However, once again the challenge is just how close the planets are going to get to each other. Even a telescope with a focal length of 1200mm (typical for a small scope) still gives a field of view 1° wide using a cropped frame camera. That’s 60 arc minutes, ten times the 6 arc minute separation of Jupiter and Saturn on December 21!
TELESCOPE TIP — Use a 2x or 3x Barlow lens if needed to increase the effective focal length of the scope. Beware that introducing a Barlow into the light path usually requires racking the focus out and/or adding extension tubes to reach focus. Test your configuration as soon as possible to make sure you can focus it.
TELESCOPE TIP — With such long focal lengths shoot lots of exposures. Some will be sharper than others.
TELESCOPE TIP — But be sure to focus precisely, and refocus over the hour or so you might be shooting, as changing temperatures will shift the focus. You can’t fix bad focus!
Jupiter and Saturn in the same telescope field on December 5, 2020. Some of the moons are visible in this exposure taken in twilight before the planets got too low in the southwest. This is a single exposure with a 130mm Astro-Physics apo refractor at f/6 (so 780mm focal length) for 4 seconds at ISO 200 with the Canon 6D MkII. The disks of the planets are overexposed to bring out the moons.
Short exposures under one second might be needed to keep the planet disks from overexposing. Capturing the moons of Jupiter (it has four bright moons) and Saturn (it has two, Titan and Rhea, that are bright) will require exposures of several seconds. Going even longer will pick up background stars.
Or … with DSLRs and mirrorless cameras, try shooting HD or 4K movies. They will likely demand a high and noisy ISO, but might capture the view more like you saw and remember it.
FINAL TIP — Whatever combination of gear you decide to use, test it! Don’t wait until December 21 to see if it works, nor ask me if I think such-and-such a mount, telescope or technique will work. Test for yourself to find out.
Jupiter and Saturn taken in the deep twilight on December 3, 2020 from the Allen Bill flats area on the Elbow River in the Kananaskis Country southwest of Calgary, Alberta. This is a blend of 4 untracked images for the dark ground, stacked to smooth noise, for 2 minutes each at ISO 400, and two tracked images for the sky (and untrailed stars) for 30 seconds each at ISO 400, all with the 35mm Canon lens at f/2.8 and Canon EOS Ra. The tracker was the Sky-Watcher Star Adventurer 2i.
Don’t Fret or Compete. Enjoy!
The finest images will come from experienced planetary imagers using high-frame-rate video cameras to shoot movies, from which software extracts and stacks the sharpest frames. Again, if you have no experience with doing that (I don’t!), this is not the time to learn!
And even the pros will have a tough time getting sharp images due to the planets’ low altitude, even from the southern hemisphere, where some pro imagers have big telescopes at their disposal, to get images no one else in the world can compete with!
In short, use the gear you have and techniques you know to capture this unique event as best you can. And if stuff fails, just enjoy the view!

This is a blend of 4 untracked images for the dark ground, stacked to smooth noise, for 2 minutes each at ISO 400, and two tracked images for the sky for 30 seconds at ISO 1600, all with the 35mm Canon lens at f/2.8 and Canon EOS Ra. The tracker was the Sky-Watcher Star Adventurer 2i.
If you miss closest approach day due to cloud, don’t worry.
Even when shooting with telephoto lenses the photo ops will be better in the week leading up to and following December 21, when the greater separation of the planets will make it easier to capture a dramatic image of the strikingly close pairing of planets over an Earthly scene.
I present my top 10 tips for capturing time-lapses of the moving sky.
If you can take one well-exposed image of a nightscape, you can take 300. There’s little extra work required, just your time. But if you have the patience, the result can be an impressive time-lapse movie of the night sky sweeping over a scenic landscape. It’s that simple.
Or is it?
Here are my tips for taking time-lapses, in a series of “Do’s” and “Don’ts” that I’ve found effective for ensuring great results.
But before you attempt a time-lapse, be sure you can first capture well-exposed and sharply focused still shots. Shooting hundreds of frames for a time-lapse will be a disappointing waste of your time if all the images are dark and blurry.
For that reason many of my tips apply equally well to shooting still images. But taking time-lapses does require some specialized gear, techniques, planning, and software. First, the equipment.
NOTE: This article appeared originally in Issue #9 of Dark Sky Travels e-magazine.
SELECTING EQUIPMENT
Essential Gear Time-lapse photography requires just the camera and lens you might already own, but on a solid tripod (a carbon-fibre Manfrotto with an Acratech ball-head is shown here), and with an intervalometer.
TIP 1 — DO: Use a solid tripod
A lightweight travel tripod that might suffice for still images on the road will likely be insufficient for time-lapses. Not only does the camera have to remain rock steady for the length of the exposure, it has to do so for the length of the entire shoot, which could be several hours. Wind can’t move it, nor any camera handling you might need to do mid-shoot, such as swapping out a battery.
The tripod needn’t be massive. For hiking into scenic sites you’ll want a lightweight but sturdy tripod. While a carbon fibre unit is costly, you’ll appreciate its low weight and good strength every night in the field. Similarly, don’t scrimp on the tripod head.
TIP 2 — DO: Use a fast lens
The All-Important Lens A fast lens is especially critical for time-lapses to allow capturing good sky and ground detail in each exposure, as compositing later won’t be feasible. This is the Sigma 20mm f/1.4 Art lens.
As with nightscape stills, the single best purchase you can make to improve your images of dark sky scenes is not buying a new camera (at least not at first), but buying a fast, wide-angle lens.
Ditch the slow kit zoom and go for at least an f/2.8, if not f/2, lens with 10mm to 24mm focal length. This becomes especially critical for time-lapses, as the fast aperture allows using short shutter speeds, which in turn allows capturing more frames in a given period of time. That makes for a smoother, slower time-lapse, and a shoot you can finish sooner if desired.
TIP 3 — DO: Use an intervalometer
Canon intervalometer functions
Nikon intervalometer functions
Automating the Camera The intervalometer is also key. For cameras without an internal intervalometer (screens from a Canon and a Nikon are shown above), an outboard unit like one of these, is essential. Be sure to get the model that fits your camera’s remote control jack.
Time-lapses demand the use of an intervalometer to automatically fire the shutter for at least 200 to 300 images for a typical time-lapse. Many cameras have an intervalometer function built into their firmware. The shutter speed is set by using the camera in Manual mode.
Just be aware that a camera’s 15-second exposure really lasts 16 seconds, while a 30-second shot set in Manual is really a 32-second exposure.
So in setting the interval to provide one second between shots, as I advise below, you have to set the camera’s internal intervalometer for an interval of 17 seconds (for a shutter speed of 15 seconds) or 33 seconds (for a shutter speed of 30 seconds). It’s an odd quirk I’ve found true of every brand of camera I use or have tested.
Alternatively, you can set the camera to Bulb and then use an outboard hardware intervalometer (they sell for $60 on up) to control the exposure and fire the shutter. Test your unit. Its interval might need to be set to only one second, or to the exposure time + one second.
How intervalometers define “Interval” varies annoyingly from brand to brand. Setting the interval incorrectly can result in every other frame being missed and a ruined sequence.
SETTING YOUR CAMERA
TIP 4 — DON’T: Underexpose
Expose to the Right When shooting, choose settings that will yield a histogram that is not slammed to the left, but is shifted to the right to minimize noise and lift details in the shadows.
As with still images, the best way to beat noise is to give the camera signal. Use a wider aperture, a longer shutter speed, or a higher ISO (or all of the above) to ensure the image is well exposed with a histogram pushed to the right.
If you try to boost the image brightness later in processing you’ll introduce not only the very noise you were trying to avoid, but also odd artifacts in the shadows such as banding and purple discolouration.
With still images we have the option of taking shorter, untrailed images for the sky, and longer exposures for the dark ground to reveal details in the landscape, to composite later. With time-lapses we don’t have that luxury. Each and every frame has to capture the entire scene well.
At dark sky sites, expose for the dark ground as much as you can, even if that makes the sky overly bright. Unless you outright clip the highlights in the Milky Way or in light polluted horizon glows, you’ll be able to recover highlight details later in processing.
After poor focus, underexposure, resulting in overly noisy images, is the single biggest mistake I see beginners make.
TIP 5 — DON’T: Worry about 500 or “NPF” Exposure Rules
Stills from a Sequence A stack of single frames from a time-lapse sequence can often make a good still image, such as this scene of the Space Station rising over Waterton Lakes National Park. The 30-second exposures were just within the “500 Rule” for the 15mm lens used here, but minor star trailing won’t be that noticeable in a final movie.
While still images might have to adhere to the “500 Rule” or the stricter “NPF Rule” to avoid star trailing, time-lapses are not so critical. Slight trailing of stars in each frame won’t be noticeable in the final movie when the stars are moving anyway.
So go for rule-breaking, longer exposures if needed, for example if the aperture needs to be stopped down for increased depth of field and foreground focus. Again, with time-lapses we can’t shoot separate exposures for focus stacking later.
Just be aware that the longer each exposure is, the longer it will take to shoot 300 of them.
Why 300? I find 300 frames is a good number to aim for. When assembled into a movie at 30 frames per second (a typical frame rate) your 300-frame clip will last 10 seconds, a decent length of time in a final movie.
You can use a slower frame rate (24 fps works fine), but below 24 the movie will look jerky unless you employ advanced frame blending techniques. I do that for auroras.
PhotoPills Calculator Apps such as PhotoPills offer handy calculators for juggling exposure time vs. the number of frames to yield the length of the time-lapse shoot.
Bonus Tip
How long it will take to acquire the needed 300 frames will depend on how long each exposure is and the interval between them. An app such as PhotoPills (via its Time lapse function) is handy in the field for calculating exposure time vs. frame count vs. shoot length, and providing a timer to let you know when the shoot is done.
TIP 6 — DO: Use short intervals
Mind the Gap! At night use intervals as short as possible to avoid gaps in time, simulated here (at top) by stacking several time-lapse frames taken at a one-second interval into one image. Using too long an interval, as demonstrated just above, yields gaps in time and jumps in the star motion, simulated here by stacking only every other frame in a sequence.
At night, the interval between exposures should be no more than one or two seconds. By “interval,” I mean the time between when the shutter closes and when it opens again for the next frame.
Not all intervalometers define “Interval” that way. But it’s what you expect it means. If you use too long an interval then the stars will appear to jump across the sky, ruining the smooth motion you are after.
In practice, intervals of four to five seconds are sometimes needed to accommodate the movement of motorized “motion control” devices that turn or slide the camera between each shot. But I’m not covering the use of those advanced units here. I cover those options and much, much more in 400 pages of tips, techniques and tutorials in my Nightscapes ebook, linked to above.
However, during the day or in twilight, intervals can be, and indeed need to be, much longer than the exposures. It’s at night with stars in the sky that you want the shutter to be closed as little as possible.
TIP 7 — DO: Shoot Raw
The Power of Raw Shooting raw, even for time-lapse frames that will eventually be turned into JPGs, allows for maximum control of shadows, highlights, colour balance, and noise reduction. “Before” is what came out of the camera; “After” is with the development settings shown applied in Camera Raw.
This advice also applies to still images where shooting raw files is essential for professional results. But you likely knew that.
However, with time-lapses some cameras offer a mode that will shoot time-lapse frames and assemble them into a movie right in the camera. Don’t use it. It gives you a finished, pre-baked movie with no ability to process each frame later, an essential step for good night time-lapses. And raw files provide the most data to work with.
So even with time-lapses, shoot raw not JPGs.
If you are confident the frames will be used only for a time-lapse, you might choose to shoot in a smaller S-Raw or compressed C-Raw mode, for smaller files, in order to fit more frames onto a card.
But I prefer not to shrink or compress the original raw files in the camera, as some of them might make for an excellent stacked and layered still image where I want the best quality originals (such as for the ISS over Waterton Lakes example above).
To get you through a long field shoot away from your computer buy more and larger memory cards. You don’t need costly, superfast cards for most time-lapse work.
PLANNING AND COMPOSITION
TIP 8 — DO: Use planning apps to frame
Planning the Shoot Apps such as The Photographer’s Ephemeris (shown here set for the author’s Waterton Lakes site for moonrise) help in planning where the Sun, Moon and Milky Way will be from your site during the shoot.
Simulating the Shoot The companion app to The Photographer’s Ephemeris, TPE 3D, shown above in the inset, exactly matches the real scene for the mountain skyline, placement of the Milky Way, and lighting from the rising Moon.
All nightscape photography benefits from using one of the excellent apps we now have to assist us in planning a shoot. They are particularly useful for time-lapses.
Apps such as PhotoPills and The Photographer’s Ephemeris are great. I like the latter as it links to its companion TPE 3D app to preview what the sky and lighting will look like over the actual topographic horizon from your site. You can scrub through time to see the motion of the Milky Way over the scenery. The Augmented Reality “AR” modes of these apps are also useful, but only once you are on site during the day.
For planning a time-lapse at home I always turn to a “planetarium” program to simulate the motion of the sky (albeit over a generic landscape), with the ability to add in “field of view” indicators to show the view your lens will capture.
You can step ahead in time to see how the sky will move across your camera frame during the length of the shoot. Indeed, such simulations help you plan how long the shoot needs to last until, for example, the galactic core or Orion sets.
Planetarium software helps ensure you frame the scene properly, not only for the beginning of the shoot (that’s easy — you can see that!), but also for the end of the shoot, which you can only predict.
Planetarium Planning An alternative is to use a planetarium program such as the free Stellarium, shown above, which can display lens fields of view. These scenes show the simulated vs. real images (insets) for the start (top) and end (bottom) of the Waterton Lakes time-lapse with a 35mm lens frame, outlined in red.
If your shoot will last as long as three hours, do plan to check the battery level and swap batteries before three hours is up. Most cameras, even new mirrorless models, will now last for three hours on a full battery, but likely not any longer. If it’s a cold winter night, expect only one or two hours of life from a single battery.
PROCESSING
TIP 9 — DO: Develop one raw frame and apply settings to all
Copy and Paste Settings Most raw developers or photo library programs (Adobe Bridge is shown here) offer the essential ability to copy settings from one image and paste them onto hundreds of others in a folder, developing all the time-lapse frames in a snap.
Processing the raw files takes the same steps and settings as you would use to process still images.
With time-lapses, however, you have to do all the processing required within your favourite raw developer software. You can’t count on bringing multiple exposures into a layer-based processor such as Photoshop to stack and blend images. That works for a single image, but not for 300.
I use Adobe Camera Raw out of Adobe Bridge to do all my time-lapse processing. But many photographers use Lightroom, which offers all the same settings and non-destructive functions as Adobe Camera Raw.
For those who wish to “avoid Adobe” there are other choices, but for time-lapse work an essential feature is the ability to develop one frame, then copy and paste its settings (or “sync” settings) to all the other frames in the set.
Not all programs allow that. Affinity Photo does not. Luminar doesn’t do it very well. DxO PhotoLab, ON1 Photo RAW, and the free Raw Therapee, among others, all work fine.
HOW TO ASSEMBLE A TIME-LAPSE
Once you have a set of raws all developed, the usual workflow is to export all those frames out as high-quality JPGs which is what movie assembly programs need. Your raw developing software has to allow batch exporting to JPGs — most do.
Photoshop Batch Export Raw developers usually have a batch export function. So does Photoshop, via its Image Processor utility, shown here (found under File>Scripts>Image Processor) that can export a folder of raws into JPGs or TIFFs, and re-size them, often needed for final 4K or HD movies.
However, none of the programs above (except Photoshop and Adobe’s After Effects) will create the final movie, whether it be from those JPGs or from the raws.
Assembling JPGs The author’s favourite assembly program is TimeLapse DeFlicker (TLDF). It can turn a folder of JPGs into movies as large as 8K and with ProRes codecs for the highest quality.
So for assembling the intermediate JPGs into a movie, I often use a low-cost program called TLDF (TimeLapse DeFlicker) available for MacOS and Windows (timelapsedeflicker.com). It offers advanced functions such as deflickering (i.e. smoothing slight frame-to-frame brightness fluctuations) and frame blending (useful to smooth aurora motions or to purposely add star trails).
While there are many choices for time-lapse assembly, I suggest using a program dedicated to the task and not, as many do, a movie editing program. For most sequences, the latter makes assembly unnecessarily difficult and harder to set key parameters such as frame rates.
TIP 10 — DO: Try LRTimelapse for more advanced processing
Working on Keyframes The advanced processing program LRTimelapse creates several keyframes through the sequence (seven are shown here in Adobe Bridge) which you develop so each looks its best. During this sequence, the Moon rose changing the lighting toward the end of the shoot (in the last three keyfames).
Get serious about time-lapse shooting and you will want — indeed, you will need — the program LRTimelapse (LRTimelapse.com). A free but limited trial version is available.
This powerful program is for sequences where one setting will not work for all the frames. One size does not fit all.
Instead, LRTimelapse allows you to process a few keyframes throughout a sequence, say at the start, middle, and end. It then interpolates all the settings between those keyframes to automatically process the entire set of images to smooth (or “ramp”) and deflicker the transitions from frame to frame.
LRTimelapse Ramping LRTimelapse reads your developed keyframe data and applies smooth transitions of all settings to each of the raw files between the keyframes. The result is a seamless and smooth final movie. The pink curve shows how the scene brightened at moonrise. The blue diamonds on the yellow line mark the seven keyframes.
This is essential for sequences where the lighting changes during the shoot (say, the Moon rises or sets), and for so-called “holy grails.” Those are advanced sequences that track from daylight or twilight to darkness, or vice versa, over a wide range of camera settings.
However, LRTimelapse works only with Adobe Lightroom or the Adobe Camera Raw/Bridge combination. So for advanced time-lapse work Adobe software is essential.
A Final Bonus Tip
Keep it simple. You might aspire to emulate the advanced sequences you see on the web, where the camera pans and dollies during the movie. I suggest avoiding complex motion control gear at first to concentrate on getting well-exposed time-lapses with just a static camera. That alone is a rewarding achievement.
But before that, first learn to shoot still images successfully. All the settings and skills you need for a great looking still image are needed for a time-lapse. Then move onto capturing the moving sky.
I end with a link to an example music video, shot using the techniques I’ve outlined. Thanks for reading and watching. Clear skies!
The Beauty of the Milky Way from Alan Dyer on Vimeo.
It was a magical night as the rising Moon lit the Badlands with a golden glow.
When doing nightscape photography it’s often best not to fight the Moon, but to embrace it and use it as your light source.
I did this on a fine night, Easter Sunday, at one of my favourite nightscape spots, Dinosaur Provincial Park.
I set up two cameras to frame different views of the hoodoos as they lit up with the light of the rising waning Moon.
The night started out as a dark moonless evening as twilight ended. Then about 90 minutes after the arrival of darkness, the sky began to brighten again as the Moon rose to illuminate the eroded formations of the Park.

Procyon is at right. Aphard in Hydra is above the hill. This is a stack of 8 exposures, mean combined to smooth noise, for the ground, and a single exposure for the sky, all with the 24mm Sigma Art lens at f/5.6 and Nikon D750 at ISO 6400, each for 25 seconds. The images were from the end of a sequence shot for a time-lapse using the TimeLapse+ View intervaolometer.
This was a fine example of “bronze hour” illumination, as some have aptly called it.
Photographers know about the “golden hour,” the time just before sunset or just after sunrise when the low Sun lights the landscape with a golden glow.
The Moon does the same thing, with a similar tone, though greatly reduced in intensity.
The low Moon, especially just after Full, casts a yellow or golden tint over the scene. This is caused by our atmosphere absorbing the “cold” blue wavelengths of moonlight, and letting through the “warm” red and yellow tones.
Making use of the rising (or setting) Moon to light a scene is one way to capture a nightscape lit naturally, and not with artificial lights, which are increasingly being frowned upon, if not banned at popular nightscape destinations.
A screen shot from the desktop app Starry Night (by Simulation Curriculum) showing the waning gibbous Moon rising in the SE on April 21. Such “planetarium” apps are useful for simulating the sky of a planned shoot.
“Bronze hour” lighting is great in still-image nightscapes. But in time-lapses the effect is more striking — indeed, in time-lapse lingo it is called a “moonstrike” scene.
The dark landscape suddenly lights up as if it were dawn, yet stars remain in the sky.
A screen shot of a planning app that is a favourite of mine, The Photographer’s Ephemeris, set up to show the scene for moonrise on April 21 from the Park.
The best nights for such a moonstrike are ones with a waning gibbous or last quarter Moon. At these phases the Moon rises after sunset, to re-light a scene after evening twilight has faded.
On April 21 I made use of such a circumstance to shoot moonstrike stills and movies, not only for their own sake, but for use as illustrations in the next edition of my Nightscapes and Time-lapse eBook (at top here).
One camera, the Nikon D750, I coupled with a device called a bramping intervalometer, in this case the TimeLapse+ View, shown above. It works great to automatically shift the shutter and ISO speeds as the sky darkens then brightens again.
Yes, in bright situations the camera’s own Auto Exposure and Auto ISO modes might accomplish this.
But … once the sky gets dark the Auto circuits fail and you’re left with hugely underexposed images.
The TimeLapse+ View, with its more sensitive built-in light meter, can track right through into full darkness, making it possible to shoot so-called “holy grail” time-lapses that go from daylight to darkness, from sunset to the Milky Way, all shot unattended.
The eroding formations of Dinosaur Provincial Park, Alberta, lit by the rising gibbous Moon, off camera at right, on April 21/22, 2019. This is looking north, with Polaris at upper centre, Capella setting at left, Vega rising at right, and the W of Cassiopeia at lower centre. This is a stack of 8 exposures, mean combined to smooth noise, for the ground, and one exposure from that set for the sky. All with the 15mm Laowa lens at f/2.8 and Sony a7III at ISO 3200, each for 30 seconds.
For the other camera, the Sony a7III (with the Laowa 15mm lens I just reviewed) I set the camera manually, then shifted the ISO and shutter speed a couple of times to accommodate the darkening, then brightening of the scene.
Processing the resulting RAW files in the highly-recommended program LRTimelapse smoothed out all the jumps in brightness to make a seamless transition.
I also used the new intervalometer function that Sony has just added to the a7III with its latest firmware update. Hurray! I complained about the lack of an intervalometer in my original review of the Sony a7III. But that’s been fixed.
This is looking north, with the stars of the northern sky pivoting around Polaris. This is a stack of 8 exposures, mean combined to smooth noise, for the ground, and 250 exposures for the sky, blended with Lighten mode to create the stails. However, I used the Advanced Stacker Plus actions in Photoshop to do the stacking, creating the tapering effect in the process. All exposures with the 15mm Laowa lens at f/2.8 and Sony a7III at ISO 3200, each for 30 seconds.
I shot 425 frames with the Sony, which I not only turned into a movie but, as one can with time-lapse frames, I also stacked into a star trail still image, in this case looking north to the circumpolar stars.
I prefer this action set over dedicated programs such as StarStaX, because it works directly with the developed Raw files. There’s no need to create a set of JPGs to stack, compromising image quality, and departing from the non-destructive workflow I prefer to maintain.
While the still images are very nice, the intended final result was this movie above, a short time-lapse vignette using clips from both cameras. Do watch in HD.
I rendered out the frames from the Sony both as a “normal” time-lapse, and as one with accumulating star trails, again using the Advanced Stacker Plus actions to create the intermediate frames for assembling into the movie.
All these techniques, gear, and apps are explained in tutorials in my eBook, above. However, it’s always great to get a night perfect for putting the methods to work on a real scene.
There’s a slogan used in the U.S. National Parks that “half the Park is after dark.” It is certainly true at Dinosaur Provincial Park in Alberta.
Last Friday night, March 29, I spent the evening at one of my favourite nightscape sites, Dinosaur Provincial Park, about an hour’s drive east of my home. It was one of those magical nights – clear, mild, dry, and no mosquitoes! Yet!
I wanted to shoot Orion and the photogenic winter sky setting into the evening twilight over the Badlands landscape. This was the last moonless weekend to do so.
I shot some individual images (such as above) and also multi-panel panoramas, created by shooting a series of overlapping images at equal spacings, then stitching them later at the computer.
This is a 240° panorama stitched from 17 segments, all with the 24mm Sigma Art lens and Nikon D750 in portrait orientation, each segment 20 seconds at f/1.4 and ISO 3200. Stitched with Adobe Camera Raw.
There’s a narrow window of time between twilight and full darkness when the Milky Way shows up well but the western sky still has a lingering blue glow. This window occurs after the normal “blue hour” favoured by photographers.
The panorama above shows the arch of the winter Milky Way but also the towering band of the Zodiacal Light rising out of the twilight and distant yellow glow of Calgary. Zodiacal Light is sunlight scattering off meteoric and cometary dust orbiting in the inner solar system, so this is a phenomenon in space not in our atmosphere. However, the narrow streak is an aircraft contrail.
A 360° panorama of the spring sky over the Badlands of Dinosaur Provincial Park, Alberta. This is a panorama of 12 segments taken with the 14mm Sigma Art lens and Nikon D750 in portrait orientation, all for 30 seconds at f/2.8 and ISO 4000. Taken at 30° spacings. Stitched with PTGui.
Later that night, when the sky was fully dark I shot this complete panorama showing not only the Milky Way and Zodiacal Light to the west, but also the faint arc of the Zodiacal Band continuing on from the pyramid-shaped Zodiacal Light over into the east, where it brightens into the subtle glow of Gegenschein. This is caused by sunlight reflecting off interplanetary dust particles in the direction opposite the Sun.
Both the Band and Gegenschein were visible to the naked eye, but only if you knew what to look for, and have a very dark sky.
This is a panorama stitched from 3 segments, all with the 24mm Sigma Art lens and Nikon D750, for 20 seconds at f/2.2 and ISO 4000. Stitched with Adobe Camera Raw.
A closeup shows the Zodiacal Light in the west as the subtle blue glow tapering toward the top as it meets the Milky Way.
It takes a dark site to see these subtle glows. Dinosaur Park is not an official Dark Sky Preserve but certainly deserves to be. Now if we could only get Calgary, Brooks and Bassano to turn down and shield their lights!
A 180° panorama of the spring sky and constellations rising in the east over the Badlands of Dinosaur Provincial Park, Alberta on March 29, 2019. This is a stitch of 6 segments, each with the 14mm Sigma Art lens and Nikon D750 in portrait mode, each 30 seconds at f/2.8 and ISO 4000. Stitched with PTGui.
A closeup facing the other way, to the east, shows the area of sky opposite the Milky Way, in the spring sky. The familiar Big Dipper, now high our spring sky, is at top with its handle pointing down to Arcturus and Spica (just rising above the horizon) – remember to “arc to Arcturus, and speed on to Spica.”
Leo is at right of centre, flanked by the Beehive and Coma Berenices star clusters.
Polaris is at left — however, the distortion introduced by the panorama stitching at high altitudes stretches out the sky at the top of the frame, so the Dipper’s Pointer stars do not point in a straight line to Polaris.
The faint Zodiacal Band is visible at right, brightening toward the horizon in the Gegenschein.
I shoot images like these for use as illustrations in future eBook projects about stargazing and the wonders of the night sky. Several are in the works!
For two magical nights I was able to capture the Rockies by moonlight, with the brilliant stars of winter setting behind the mountains.
I’ve been waiting for nights like these for many years! I consider this my “25-Year Challenge!”
Back during my early years of shooting nightscapes I was able to capture the scene of Orion setting over Lake Louise and the peaks of the Continental Divide, with the landscape lit by the Moon.
Such a scene is possible only in late winter, before Orion sets out of sight and, in March, with a waxing gibbous Moon to the east to light the scene but not appear in the scene. There are only a few nights each year the photograph is possible. Most are clouded out!
Orion over Lake Louise, Banff National Park, Alberta March 1995 at Full Moon 28mm lens at f/2.8 Ektachrome 400 slide film
Above is the scene in March 1995, in one of my favourite captures on film. What a night that was!
But it has taken 24 years for my schedule, the weather, and the Moon phase to all align to allow me to repeat the shoot in the digital age. Thus the Challenge.
Here’s the result.
Orion setting over the iconic Victoria Glacier at Lake Louise, with the scene lit by the light of the waxing Moon, on March 19, 2019. This is a panorama of 3 segments stitched with Adobe Camera Raw, each segment 8 seconds at f/3.5 with the Sigma 24mm Art lens and Nikon D750 at ISO 800.
Unlike with film, digital images make it so much easier to stitch multiple photos into a panorama.
In the film days I often shot long single exposures to produce star trails, though the correct exposure was an educated guess factoring in variables like film reciprocity failure and strength of the moonlight.
Below is an example from that same shoot in March 1995. Again, one of my favourite film images.
Orion setting over Mount Temple, near Lake Louise, Banff National park, Alberta. March 1995. On Ektachrome 100 slide film, with a 28mm lens at f/8 for a roughly 20 minute exposure. Full moonlight provides the illumination
This year, time didn’t allow me to shoot enough images for a star trail. In the digital age, we generally shoot lots of short exposures to stack them for a trail.
Instead, I shot this single image of Orion setting over Mt. Temple.
The winter stars of Orion (centre), Canis Major (left) and Taurus (upper right) over Mt. Temple in Banff National Park. This is from the Morant’s Curve viewpoint on the Bow Valley Parkway, on March 19, 2019. Illumination is from moonlight from the waxing gibbous Moon off frame to the left. This is a single 8-second exposure at f/3.2 with the 24mm Sigma Art lens and Nikon D750 at ISO 800.
Plus I shot the panorama below, both taken at Morant’s Curve, a viewpoint named for the famed CPR photographer Nicholas Morant who often shot from here with large format film cameras. Kevin Keefe of Trains magazine wrote a nice blog about Morant.
A panorama of Morant’s Curve, on the Bow River in Banff National Park, with an eastbound train on the CPR tracks under the stars of the winter sky. Illumination is from the 13-day gibbous Moon off frame at left. Each segment is 8 seconds at f/3.2 and ISO 800 with the 24mm Sigma Art lens and Nikon D750 in portrait orientation.
I was shooting multi-segment panoramas when a whistle in the distance to the west alerted me to the oncoming train. I started the panorama segment shooting at the left, and just by good luck the train was in front of me at centre when I hit the central segment. I continued to the right to catch the blurred rest of the train snaking around Morant’s Curve. I was very pleased with the result.
The night before I was at another favourite spot, Two Jack Lake near Banff, to again shoot panoramas of the moonlit scene below the bright stars of the winter sky.
These are the iconic red chairs of Parks Canada, here at frozen Two Jack Lake, Banff National Park, and under the moonlit winter sky. This was March 18, 2019, with the scene illuminated by the gibbous Moon just at the frame edge here. This is a panorama of 11-segments, each 10 seconds at f/4 with the Sigma 24mm Art lens and Nikon D750 at ISO 800.
A run up to the end of the Vermilion Lakes road at the end of that night allowed me to capture Orion and Siris reflected in the open water of the upper lake.
The winter stars setting at Vermilion Lakes in Banff National Park, on March 18, 2019. This is a panorama cropped from a set of 11 images, all with the 24mm Sigma Art lens at f/3.2 for 10 seconds each and the Nikon D750 at ISO 800, in portrait orientation.
Unlike in the film days, today we also have some wonderful digital planning tools to help us pick the right sites and times to capture the scene as we envision it.
This is a screen shot of the PhotoPills app in its “augmented reality” mode, taken by day during a scouting session at Two Jack, but showing where the Milky Way will be later that night in relation to the real “live” scene shot with the phone’s camera.
PhotoPills
The app I like for planning before the trip is The Photographer’s Ephemeris. This is a shot of the plan for the Lake Louise shoot. The yellow lines are the sunrise and sunset points. The thin blue line at lower right is the angle toward the gibbous Moon at about 10 p.m. on March 19.

Even better than TPE is its companion program TPE 3D, which allows you to preview the scene with the mountain peaks, sky, and illumination all accurately simulated for your chosen location. I am impressed!

Compare the simulation above to the real thing below, in a wide 180° panorama.
A panorama of Lake Louise in winter, in Banff National Park, Alberta, taken under the light of the waxing gibbous Moon, off frame here to the left. This was March 19, 2019. This is a crop from the original 16-segment panorama, each segment with the 24mm Sigma Art lens and Nikon D750, oriented “portrait.” Each segment was 8 seconds at f/3.2 and ISO 800.
These sort of moonlit nightscapes are what I started with 25 years ago, as they were what film could do well.
These days, everyone chases after dark sky scenes with the Milky Way, and they do look wonderful, beyond anything film could do. I shoot many myself. And I include an entire chapter in my ebook above about shooting the Milky Way.
But … there’s still a beauty in a contrasty moonlit scene with a deep blue sky from moonlight, especially with the winter sky and its population of bright stars and constellations.
These are the iconic red chairs of Parks Canada, here on the Tunnel Mountain Drive viewpoint overlooking the Bow River and Mount Rundle, in Banff National Park, and under the moonlit winter sky. This is a panorama cropped from the original 12-segments, each 15 seconds at f/4 with the Sigma 24mm Art lens and Nikon D750 at ISO 800.
I’m glad the weather and Moon finally cooperated at the right time to allow me to capture these magical moonlit panoramas.
It took a chase but it was worth it to catch the January 20, 2019 total eclipse of the Moon in the winter sky.
While the internet and popular press fawned over the bogus moniker of “Super Blood Wolf” Moon, to me this was the “Cold Moon” eclipse. And I suspect that was true for many other observers and eclipse chasers last Sunday.
Total solar eclipses almost always involve a chase, usually to far flung places around the world to stand in the narrow shadow path. But total lunar eclipses (TLEs) come to you, with more than half the planet able to view the Moon pass through the Earth’s shadow and turn red for several minutes to over an hour.
The glitch is clouds. For several of the last TLEs I have had to chase, to find clear skies in my local area, creating pre-eclipse stress … and post-eclipse relief!
A screen shot from Astrospheric
That was the case for the January 20, 2019 total lunar, as the weather predictions above, based on Environment Canada data, were showing east-central Alberta along the Saskatchewan border as the only clear hole within range and accessible.
The above is a screen shot from the wonderful app Astrospheric, a recommended and great aid to astronomers. In 2014, 2015, and 2018 the Environment Canada predictions led me to clear skies, allowing me to see an eclipse that others in my area missed.
So trusting the predictions, the day before the eclipse I drove the 5 hours and 500 km north and east to Lloydminster, a town where the provincial border runs right down the main street, Highway 17.
A screen shot from Theodolite
The morning of the evening eclipse, I drove up and down that highway looking for a suitable site to setup. Scenery was not in abundance! It’s farm land and oil wells. I settled for a site shown above, an access road to a set of wells and tanks where I would likely not be disturbed, that had no lights, and had a clear view of the sky.
The image above is from the iOS app Theodolite, another fine app for planning and scouting sites, as it overlays where the camera was looking.
Scenery was not a priority as I was mostly after a telephoto view of the eclipsed Moon near the Beehive star cluster. Wide views would be a bonus if I could get them, for use in further ebook projects, as is the plan for the image below.
This is a single untracked exposure of 25 seconds at f/2.8 and ISO 1600 with the Nikon D750 and Sigma 20mm Art lens, but with a shorter exposure of 1 second blended in for the Moon itself so it retains its color and appearance to the naked eye. Your eye can see the eclipsed Moon and Milky Way well but the camera cannot in a single exposure. The scene, taken just after the start of totality, just fit into the field of the 20mm lens. A little later in the night it did not.
The site, which was east of the border in Saskatchewan, served me well, and the skies behaved just as I had hoped, with not a cloud nor haze to interfere with the view. It was a long and cold 5-hour night on the Prairies, with the temperature around -15° C.
It could have been worse, with -25° not uncommon at this time of year. And fortunately, the wind was negligible, with none of the problems with frost that can happen on still nights.
Nevertheless, I kept my photo ambitions in check, as in the cold much can go wrong and running two cameras was enough!
The Moon in mid-total eclipse, on January 20, 2019, with it shining beside the Beehive star cluster, Messier 44, in Cancer. This view tries to emulate the visual scene through binoculars, though the camera picks up more stars and makes the Moon more vivid than it appears to the eye. However, creating a view that looks even close to what the eye can see in this case takes a blend of exposures: a 1-minute exposure at ISO 800 and f/2.8 for the stars, which inevitably overexposes the Moon. So I’ve blended in three shorter exposures for the Moon, taken immediately after the long “star” exposure. These were 8, 4 and 2 seconds at ISO 400 and f/4, and all with the Canon 200mm telephoto on a Fornax Lightrack II tracking mount to follow the stars.
Above was the main image I was after, capturing the red Moon shining next to the Beehive star cluster, a sight we will not see again for another 18-year-long eclipse “saros,” in January 2037.
But I shot images every 10 minutes, to capture the progression of the Moon through the shadow of the Earth, for assembly into a composite. I’d pick the suitable images later and stack them to produce a view of the Moon and umbral shadow outline set amid the stars.
The Moon in total eclipse, on January 20, 2019, in a multiple exposure composite showing the Moon moving from right to left (west to east) through the Earth’s umbral shadow. The middle image is from just after mid-totality at about 10:21 pm MST, while the partial eclipse shadow ingress image set is from 9:15 pm and the partial eclipse shadow egress image set is from 11:15 pm. I added in two images at either end taken at the very start and end of the umbral eclipse to add a more complete sequence of the lunar motion. The central image of totality includes a 1-minute exposure at ISO 800 and f/2.8 for the stars, which inevitably overexposes the Moon. So I’ve blended in three shorter exposures for the Moon, taken immediately after the long “star” exposure. These were 8, 4 and 2 seconds at ISO 400 and f/4, and all with the Canon 200mm telephoto. The two partial eclipse phases are stacks of 7 exposures each, from very short for the bright portion of the lunar disk, to long for the shadowed portion. They are blended with luminosity masks created with ADP Pro v3 panel for Photoshop, but modified with feathering to blend the images smoothly.
Above is the final result, showing the outline of the circular umbral shadow of the Earth defined by the shadow edge on the partially eclipsed Moons. The umbra is about three times the size of the Moon. And at this eclipse the Moon moved across the northern half of the shadow.
So mission accomplished!
This is an untracked single exposure of 15 seconds at ISO 3200 and f/2.8 with the Sigma 20mm Art lens and Nikon D750. However, I blended in a shorter 1-second exposure for the red eclipsed Moon itself to prevent its disk from overexposing as it would in any exposure long enough to record the Milky Way.
I usually try to take a “trophy” shot of the successful eclipse chaser having bagged his game. This is it, from mid-eclipse during totality, with the red Moon shining in the winter sky beside the Beehive.
With this eclipse I can now say I have seen every total lunar eclipse visible from my area of the world since May 2003. I’m not counting those TLEs that were visible from only the eastern hemisphere — I’m not so avid as to chase those. And there were a couple of TLEs in that time that were visible from North America, but not from Alberta. So I’m not counting those.
And a couple of TLEs that were visible from here I did not see from here in Alberta — I saw April 15, 2014 from Australia and April 4, 2015 from Utah.
With that tally I’ve seen all the locally visible TLEs over a full saros cycle, 18 years. The last local TLE I missed was January 20, 2000, exactly 19 years — a Metonic cycle — ago. It must have been cloudy!
The next total eclipse of the Moon is May 26, 2021, visible from Alberta as the Moon sets at dawn. I’d like to be in Australia for that one (depicted above in a screen shot from StarryNight™), to see the eclipsed Moon beside the galactic centre as both rise in the east, a sight to remember. Being late austral autumn, that will be a “cool Moon.”
On the evening of January 20 for North America, the Full Moon passes through the umbral shadow of the Earth, creating a total eclipse of the Moon.
No, this isn’t a “blood,” “super,” nor “wolf” Moon. All those terms are internet fabrications designed to bait clicks.
It is a totallunareclipse — an event that doesn’t need sensational adjectives to hype, because they are always wonderful sights! And yes, the Full Moon does turn red.
As such, on January 20 the evening and midnight event provides many opportunities for great photos of a reddened Moon in the winter sky.
Here’s my survey of tips and techniques for capturing the eclipsed Moon.
First … What is a Lunar Eclipse?
As the animation below shows (courtesy NASA/Goddard Space Flight Center), an eclipse of the Moon occurs when the Full Moon (and they can happen only when the Moon is exactly full) travels through the shadow of the Earth.
The Moon does so at least two times each year, though often not as a total eclipse, one where the entire disk of the Moon enters the central umbral shadow. Many lunar eclipses are of the imperceptible penumbral variety, or are only partial eclipses.
Total eclipses of the Moon can often be years apart. The last two were just last year, on January 31 and July 27, 2018. However, the next is not until May 26, 2021.
At any lunar eclipse we see an obvious darkening of the lunar disk only when the Moon begins to enter the umbra. That’s when the partial eclipse begins, and we see a dark bite appear on the left edge of the Moon.
While it looks as if Earth’s shadow sweeps across the Moon, it is really the Moon moving into, then out of, our planet’s umbra that causes the eclipse. We are seeing the Moon’s revolution in its orbit around Earth.
At this eclipse the partial phases last 67 minutes before and after totality.
This shows the length of the eclipse phases relative to the start of the partial eclipse as the Moon begins to enter the umbra at right. The Moon’s orbital motion takes it through the umbra from right to left (west to east) relative to the background stars. The visible eclipse ends 196 minutes (3 hours and 16 minutes) after it began. Click or tap on the charts to download a high-res version.
Once the Moon is completely immersed in the umbra, totality begins and lasts 62 minutes at this eclipse, a generous length.
The Moon will appear darkest and reddest at mid-eclipse. During totality the lunar disk is illuminated only by red sunlight filtering through Earth’s atmosphere. It is the light of all the sunsets and sunrises going on around our planet.
And yes, it is perfectly safe to look at the eclipsed Moon with whatever optics you wish. Binoculars often provide the best view. Do have a pair handy!
Total eclipse of the Moon, December 20/21, 2010, taken from home with 130mm AP apo refractor at f/6 and Canon 7D at ISO 400 for 4 seconds, single exposure, shortly after totality began.
At this eclipse because the Moon passes across the north half of the umbra, the top edge of the Moon will always remain bright, as it did above in 2010, looking like a polar cap on the reddened Moon.
Near the bright edge of the umbra look for subtle green and blue tints the eye can see and that the camera can capture.
Where is the Eclipse?
As the chart below shows, all of the Americas can see the entire eclipse, with the Moon high in the evening or late-night sky. For the record, the Moon will be overhead at mid-eclipse at local midnight from Cuba!
All of the Americas can see this eclipse. The eclipse gets underway as the Moon sets at dawn over Europe. Diagram courtesy EclipseWise.com
I live in Alberta, Canada, at a latitude of 50 degrees North. And so, the sky charts I provide here are for my area, where the Moon enters the umbral shadow at 8:35 p.m. MST with the Moon high in the east. By the end of totality at 10:44 p.m. MST the Moon shines high in the southeast. This sample chart is for mid-eclipse at my site.
The sky at mid-eclipse from my Alberta site. Created with the planetarium software Starry Night, from Simulation Curriculum.
I offer them as examples of the kinds of planning you can do to ensure great photos. I can’t provide charts good for all the continent because exactly where the Moon will be during totality, and the path it will take across your sky will vary with your location.
In general, the farther east and south you live in North America the higher the Moon will appear. But from all sites in North America the Moon will always appear high and generally to the south.
To plan your local shoot, I suggest using planetarium software such as the free Stellarium or Starry Night (the software I used to prepare the sky charts in this post), and photo planning apps such as The Photographer’s Ephemeris or PhotoPills.
The latter two apps present the sightlines toward the Moon overlaid on a map of your location, to help you plan where to be to shoot the eclipsed Moon above a suitable foreground, if that’s your photographic goal.
When is the Eclipse?
While where the Moon is in your sky depends on your site, the various eclipse events happen at the same time for everyone, with differences in hour due only to the time zone you are in.
While all of North America can see the entirety of the partial and total phases of this eclipse (lasting 3 hours and 16 minutes from start to finish), the farther east you live the later the eclipse occurs, making for a long, late night for viewers on the east coast.
Those in western North America can enjoy all of totality and be in bed at or before midnight.
Here are the times for the start and end of the partial and total phases. Because the penumbral phases produce an almost imperceptible darkening, I don’t list the times below for the start and end of the penumbral eclipse.
PM times are on the evening of January 20.
AM times are after midnight on January 21.
Note that while some sources list this eclipse as occurring on January 21, that is true for Universal Time (Greenwich Time) and for sites in Europe where the eclipse occurs at dawn near moonset.
For North America, if you go out on the evening of January 21 expecting to see the eclipse you’ll be a day late and disappointed!
Picking a Photo Technique
Lunar eclipses lend themselves to a wide range of techniques, from a simple camera on a tripod, to a telescope on a tracking mount following the sky.
If this is your first lunar eclipse I suggest keeping it simple! Select just one technique, to focus your attention on only one camera on a cold and late winter night.
The total eclipse of the Moon of September 27, 2015, through a telescope, at mid-totality with the Moon at its darkest and deepest into the umbral shadow, in a long exposure to bring out the stars surrounding the dark red moon. This is a single exposure taken through a 92mm refractor at f/5.5 for 500mm focal length using the Canon 60Da at ISO 400 for 8 seconds. The telescope was on a SkyWatcher HEQ5 equatorial mount tracking at the lunar rate.
Then during the hour of totality take the time to enjoy the view through binoculars and with the unaided eye. No photo quite captures the glowing quality of an eclipsed Moon. But here’s how to try it.
Option 1: Simple — Camera-on-Tripod
The easiest method is to take single shots using a very wide-angle lens (assuming you also want to include the landscape below) with the camera on a fixed tripod. No fancy sky trackers are needed here.
During totality, with the Moon now dimmed and in a dark sky, use a good DSLR or mirrorless camera in Manual (M) mode (not an automatic exposure mode) for settings of 2 to 20 seconds at f/2.8 to f/4 at ISO 400 to 1600.
That’s a wide range, to be sure, but it will vary a lot depending on how bright the sky is at your site. Shoot at lots of different settings, as blending multiple exposures later in processing is often the best way to reproduce the scene as your eyes saw it.
Shoot at a high ISO if you must to prevent blurring from sky motion. However, lower ISOs, if you can use them by choosing a slower shutter speed or wider lens aperture, will yield less digital noise.
Focus carefully on a bright star, as per the advice below for telephoto lenses. Don’t just set the lens focus to infinity, as that might not produce the sharpest stars.
Total eclipse of the Moon, December 20/21, 2010, with 15mm lens at f/3.2 and Canon 5D MkII at ISO 1600 for a 1-minute tracked exposure. Without a tracker, use shorter exposures (less than 20 seconds) and higher ISOs or wider apertures to avoid trailing,
One scene to go for at this eclipse is similar to the above photo, with the reddened Moon above a winter landscape and shining east of Orion and the winter Milky Way. But that will require shooting from a dark site away from urban lights. But when the Moon is totally eclipsed, the sky will be dark enough for the Milky Way to appear.
Click or tap on any of the charts to download a high-resolution copy.
The high altitude of the Moon at mid-eclipse from North America (with it 40 to 70 degrees above the horizon) will also demand a lens as wide as 10mm to 24mm, depending whether you use portrait or landscape orientation, and if your camera uses a cropped frame or full frame sensor. The latter have the advantage in this category of wide-angle nightscape.
Alternatively, using a longer 14mm to 35mm lens allows you to frame the Moon beside Orion and the winter Milky Way, as above, but without the landscape. Again, this will require a dark rural site.
If you take this type of image with a camera on a fixed tripod, use high ISOs to keep exposures below 10 to 20 seconds to avoid star trailing. You have an hour of totality to shoot lots of exposures to make sure some will work best.
Total eclipse of the Moon, December 20/21, 2010, with Canon 5D MKII and 24mm lens at f2.8 for stack of four 2-minute exposures at ISO 800. Taken during totality using a motorized sky tracker. The eclipsed Moon is the red object above Orion, and the stars appear bloated due to high haze and fog rolling in.
If you have a sky tracker to follow the stars, as I did above, exposures can be much longer — perhaps a minute to pick up the Milky Way really well — and ISOs can be lower to avoid noise.
Option 1 Variation — Urban Eclipses
Unfortunately, point-and-shoot cameras and so-called “bridge” cameras, ones with non-interchangeable lenses, likely won’t have lenses wide enough to capture the whole scene, landscape and all. Plus their sensors will be noisy when used at high ISOs. Those cameras might be best used to capture moderate telephoto closeups at bright urban sites.
With any camera, at urban sites look for scenic opportunities to capture the eclipsed Moon above a skyline or behind a notable landmark. By looking up from below you might be able to frame the Moon beside a church spire, iconic building, or a famous statue using a normal or short telephoto lens, making this a good project for those without ultra-wide lenses.
Lunar eclipse, Feb 20, 2008 with a 135mm telephoto and Canon 20Da camera showing the Moon’s size with such a lens and cropped-frame camera. This is a blend of 8-second and 3-second exposures to bring out stars and retain the Moon. Both at ISO200 and f/2.8. Saturn is at lower left and Regulus at upper right.
Whatever your lens or subject, at urban sites expose as best you can for the foreground, trying to avoid any bright and bare lights in the frame that will flood the image with lens flares in long exposures.
Capturing such a scene during the deep partial phases might produce a brighter Moon that stands out better in an urban sky than will a photo taken at mid-totality when the Moon is darkest.
TIP: Practice, Practice, Practice!
With any camera, especially beginner point-and-shoots, ensure success on eclipse night by practicing shooting the Moon before the eclipse, during the two weeks of the waxing Moon leading up to Full Moon night and the eclipse.
The crescent Moon with Earthshine on the dark side of the Moon is a good stand-in for the eclipsed Moon. Set aside the nights of January 8 to 11 to shoot the crescent Moon. Check for exposure and focus. Can you record the faint Earthshine? It’s similar in brightness to the shadowed side of the eclipsed Full Moon.
The next week, on the nights of January 18 and 19, the waxing gibbous Moon will be closer to its position for eclipse night and almost as bright as the uneclipsed Full Moon, allowing some rehearsals for shooting it near a landmark.
Option 2: Advanced — Multiple Exposures
An advanced method is to compose the scene so the lens frames the entire path of the Moon for the 3 hours and 16 minutes from the start to the end of the partial eclipse.
This set of 3 charts shows the position of the Moon at the start, middle, and end of the eclipse, for planning lens choice and framing of the complete eclipse path. The location is Alberta, Canada.
As shown above, including the landscape will require at least a 20mm lens on a full frame camera, or 12mm lens on a cropped frame camera. However, these charts are for my site in western Canada. From sites to the east and south where the Moon is higher an even wider lens might be needed, making this a tough sequence to take.
With wide lenses, the Moon will appear quite small. The high altitude of the Moon and midnight timing won’t lend itself to this type of multiple image composite as well as it does for eclipses that happen near moonrise or moonset, as per the example below.
This is a multiple-exposure composite of the total lunar eclipse of Sunday, September 27, 2015, as shot from Writing-on-Stone Provincial Park, Alberta, Canada. For this still image composite of the eclipse from beginning to end, I selected just 40 frames taken at 5-minute intervals, out of 530 I shot in total, taken at 15- to 30-second intervals for the full time-lapse sequence included below.
A still-image composite with the lunar disks well separated will need shots only every 5 minutes, as I did above for the September 27, 2015 eclipse.
Exposures for any lunar eclipse are tricky, whether you are shooting close-ups or wide-angles, because the Moon and sky change so much in brightness.
As I did for the image below, for a still-image composite, you can expose just for the bright lunar disk and let the sky go dark.
Exposures for just the Moon will range from very short (about 1/500th second at f/8 and ISO 100) for the partials, to 1/2 to 2 seconds at f/2.8 to f/4 and ISO 400 for the totals, then shorter again (back to 1/500 at ISO 100) for the end shots when the Full Moon has returned to its normal brilliance.
That’ll take constant monitoring and adjusting throughout the shoot, stepping the shutter speed gradually longer thorough the initial partial phase, then shorter again during the post-totality partial phase.
You’d then composite and layer (using a Lighten blend mode) the well-exposed disks (surrounded by mostly black sky) into another background image exposed longer for 10 to 30 seconds at ISO 800 to 1600 for the sky and stars, shot at mid-totality.
To maintain the correct relative locations of the lunar disks and foreground, the camera cannot move.
The total lunar eclipse of April 4, 2015 taken from near Tear Drop Arch, in western Monument Valley, Utah. I shot the totality images during the short 4 minutes of totality. The mid-totality image is a composite of 2 exposures: 30 seconds at f/2.8 and ISO 1600 for the sky and landscape, with the sky brightening blue from dawn twilight, and 1.5 seconds at f/5.6 and ISO 400 for the disk of the Moon itself. Also, layered in are 26 short exposures for the partial phases, most being 1/125th sec at f/8 and ISO 400, with ones closer to totality being longer, of varying durations.
That technique works best if it’s just a still image you are after, such as above. This image is such a composite, of the April 4, 2015 total lunar eclipse from Monument Valley, Utah.
This type of composite takes good planning and proper exposures to pull off, but will be true to the scene, with the lunar disk and its motion shown to the correct scale and position as it was in the sky. It might be a composite, but it will be accurate.
My Rant!
That’s in stark contrast to the flurry of ugly “faked” composites that will appear on the web by the end of the day on January 21, ones with huge telephoto Moons pasted willy-nilly onto a wide-angle sky.
Rather than look artistic, most such attempts look comically cut-and-pasted. They are amateurish. Don’t do it!
Option 3: Advanced — Wide-Angle Time-Lapses
If it’s a time-lapse movie you want (see the video below), take exposures every 10 to 30 seconds, to ensure a final movie with smooth motion.
Unlike shooting for a still-image composite, for a time lapse each frame will have to be exposed well enough to show the Moon, sky, and landscape.
That will require exposures long enough to show the sky and foreground during the partial phases — likely about 1 to 4 seconds at f/2.8 and ISO 400. In this case, the disk of the partially-eclipsed Moon will greatly overexpose, as it does toward the end of the above time-lapse from September 27, 2015..
But the Moon will darken and become better exposed during the late stages of the partial eclipse and during totality when a long exposure — perhaps now 10 to 20 seconds at f/2.8 and ISO 800 to 1600 — will record the bright red Moon amid the stars and winter Milky Way.
Maintaining a steady cadence during the entire sequence requires using an interval long enough throughout to accommodate the expected length of the longest exposure at mid-totality, with similar camera settings to what you’ve used for other Milky Way nightscapes. If you’ve never taken those before, then don’t attempt this complex sequence.
After totality, as the Moon and sky re-brighten, exposures will have to shorten again, andsymmetrically in reverse fashion for the final partial phases.
Such a time-lapse requires consistently and incrementally adjusting the camera over the three or more hours of the eclipse on a cold winter night. The high altitude of the Moon and its small size on the required wide angle lenses will make any final time lapse less impressive than at eclipses that occur when the Moon is rising or setting.
But … the darkening of the sky and “turning on” of the Milky Way during totality will make for an interesting time-lapse effect. The sky and scene will be going from a bright fully moonlit night to effectively a dark moonless night, then back to moonlit. It’s a form of “holy grail” time lapse, requiring advanced processing with LRTimelapse software.
Again, do not move the camera. Choose your lens and frame your camera to include the entire path of the Moon for as long as you plan to shoot.
Even if the final movie looks flawed, individual frames should still produce good still images, or a composite built from a subset of the frames.
Option 4: Simple — Telephoto Close-Ups
The first thought of many photographers is to shoot the eclipse with as long a telephoto lens as possible. That can work, but …
The harsh reality is that the Moon is surprisingly small (only 1/2-degree across) and needs a lot of focal length to do it justice, if you want a lunar close-up.
You’ll need a 300mm to 800mm lens. Unfortunately, the Moon and sky are moving and any exposures over 1/4 to 2 seconds (required during totality) will blur the Moon badly if its disk is large on the frame and all you are using is a fixed tripod.
If you don’t have a tracking mount, one solution is to keep the Moon’s disk small (using no more than a fast f/2 or f/2.8 135mm to 200mm lens) and exposures short by using a high ISO speed of 1600 to 3200. Frame the Moon beside the Beehive star cluster as I show below.
Take a range of exposures. But … be sure to focus!
TIP: Focus! And Focus Again!
Take care to focus precisely on a bright star using Live View. That’s true of any lens but especially telephotos and telescopes.
Focus not just at the start of the night, but also more than once again later at night. Falling temperatures on a winter night will cause long lenses and telescopes to shift focus. What was sharp at the start of the eclipse won’t be by mid totality.
The catch is that if you are shooting for a time-lapse or composite you likely won’t be able to re-point the optics to re-focus on a star in mid-eclipse. In that case, be sure to set up the gear well before you want to start shooing to let it cool to ambient air temperature. Now focus on a star, then frame the scene. Then hope the lens doesn’t shift off focus. You might be able to focus on the bright limb of the Moon but it’s risky.
Fuzzy images, not bad exposures, are the ruin of most attempts to capture a lunar eclipse, especially with a telephoto lens. And the Moon itself, especially during totality, is not a good target to focus on. Use a bright star. The winter sky has lots!
Option 5: Advanced — Tracked Telescopic Close-Ups
If you have a mount that can be polar aligned to track the sky, then many more options are open to you.
You can use a telescope mount or one of the compact and portable trackers, such as the Sky-Watcher Star Adventurer (I show the Mini model above) or iOptron Sky Tracker units. While these latter units work great, you are best to keep the payload weight down and your lens size well under 300mm.
That’s just fine for this eclipse, as you really don’t need a frame-filling Moon. The reason is that the Moon will appear about 6 degrees west of the bright star cluster called the Beehive, or Messier 44, in Cancer.
As shown above, a 135mm to 200mm lens will frame this unique pairing well. For me, that will be the signature photo of this eclipse. The pairing can happen only at lunar eclipses that occur in late January, and there won’t be any more of those until 2037!
That’s the characteristic that makes this eclipse rare and unique, not that it’s a “super-duper, bloody, wolf Moon!” But it doesn’t make for a catchy headline.
A High Dynamic Range composite of 7 exposures of the Dec 20/21, 2010 total lunar eclipse, from 1/2 second to 30 seconds, to show the more normally exposed eclipsed Moon with the star cluster M35, at left, in Gemini, to show the scene as it appeared in binoculars. Each tracked photo taken with a 77mm Borg apo refractor at f/4.2 (300mm focal length) and Canon 5D MkII at ISO 1600.
Exposures to show the star cluster properly might have to be long enough (30 to 120 seconds) that the Moon overexposes, even at mid-totality. If so, take different exposures for the Moon and stars, then composite them later, as I did above for the December 20, 2010 eclipse near the Messier 35 star cluster in Gemini.
If really you want to shoot with even more focal length for framing just the Moon, a monster telephoto lens will work, but a small telescope such as an 80mm aperture f/6 to f/7 refractor will provide enough focal length and image size at much lower cost and lighter weight, and be easier to attach to a telescope mount.
But even with a 500mm to 800mm focal length telescope the Moon fills only a small portion of the frame, though cropped frame cameras have the advantage here. Use one if it’s a big Moon you’re after!
No matter the camera, the lens or telescope should be mounted on a solid equatorial telescope mount that you must polar align earlier in the night to track the sky.
Alternatively, a motorized Go To telescope on an alt-azimuth mount will work, but only for single shots. The rotation of the field with alt-az mounts will make a mess of any attempts to shoot multiple-exposure composites or time-lapses, described below.
Whatever the mount, for the sharpest lunar disks during totality, use the Lunar tracking rate for the motor.
This series shows the need to constantly shift exposure by lengthening the shutter speed as the eclipse progresses. Do the same to shorten the exposure after totality. The exposures shown here are typical.
Assuming an f-ratio of f/6 to f/8, exposures will vary from as short as 1/250th second at ISO 100 to 200 for the barely eclipsed Moon, to 4 to 20 seconds at ISO 400 to 1600 for the Moon at mid-totality.
It’s difficult to provide a precise exposure recommendation for totality because the brightness of the Moon within the umbra can vary by several stops from eclipse to eclipse, depending on how much red sunlight manages to make it through Earth’s atmospheric filter to light the Moon.
TIP: Shoot for HDR
Total eclipse of the Moon, December 20/21, 2010, with 5-inch refractor at f/6 (780mm focal length) and Canon 7D (cropped frame camera) at ISO 400. This is an HDR blend of 9 images from 1/125 second to 2 seconds, composited in Photoshop. Note the blue tint along the shadow edge.
As I did above, during the deep partial phases an option is to shoot both long, multi-second exposures for the red umbra and short, split-second exposures for the bright part of the Moon not yet in the umbra.
Take 5 to 7 shots in rapid succession, covering the range needed, perhaps at 1-stop increments. Merge those later with High Dynamic Range (HDR) techniques and software, or with luminosity masks.
Even if you’re not sure how to do HDR processing now, shoot all the required exposures anyway so you’ll have them when your processing skills improve.
Option 6: Advanced — Close-Up Composites and Time-Lapses
With a tracking telescope on an equatorial mount you could fire shots every 10 to 30 seconds, and then assemble them into a time-lapse movie, as below.
But as with wide-angle time-lapses, that will demand constant attention to gradually and smoothly shift exposures, ideally by 1/3rd-stop increments every few shots during the partial and total phases. Make lots of small adjustments, rather than fewer large ones.
If you track at the lunar rate, as I did above, the Moon should stay more or less centred while it drifts though the stars, assuming your mount is accurately polar aligned, an absolutely essential prerequisite here.
Composite image digitally created in Photoshop of images taken during October 27, 2004 total lunar eclipse, from Alberta Canada. Images taken through 5-inch apo refractor at f/6 with Canon Digital Rebel 300D camera at ISO 200.
Conversely, track at the sidereal rate and the stars will stay more or less fixed while the Moon drifts through the frame from right to left (west to east) as I show above in a composite of the October 27, 2004 eclipse.
But such a sequence takes even more careful planning to position the Moon correctly at the start of the sequence so it remains “in frame” for the duration of the eclipse, and ends up where you want at the end.
In the chart below, north toward Polaris is at the top of the frame. Position the Moon at the start of the eclipse so it ends up just above the centre of the frame at mid-eclipse. Tricky!
Repeated from earlier, this chart shows the path of the Moon through the north half of the umbra, a path that will be the same for any site, as will be the timing. North is up here.
As I show above, for this type of “Moon-thru-shadow” sequence a focal length of about 400mm is ideal on a full frame camera, or 300mm on a cropped frame camera.
From such a time-lapse set you could also use several frames selected from key stages of the eclipse, as I did in 2004, to make up a multiple-image composite showing the Moon moving through the Earth’s shadow.
Again, planetarium software such as Starry Night I used above, which can be set to display the field of view of the camera and lens of your choice, is essential to plan the shoot. Don’t attempt it without the right software to plan the framing.
I would consider the telescopic time-lapse method the most challenging of techniques. Considering the hour of the night and the likely cold temperatures, your best plan might be to keep it simple.
It’s what I plan to do.
I’ll be happy to get a tracked telephoto close-up of the Moon and Beehive cluster as my prime goal, with a wide-angle scene of the eclipsed Moon beside Orion and the Milky Way as a bonus. A few telescope close-ups will be even more of a bonus.

The next total eclipse of the Moon anywhere on Earth doesn’t occur until May 26, 2021 in an event visible at dawn from Western North America. The next total lunar eclipse visible from all of North America comes a lunar year later, on May 15, 2022.

I spent a wonderful week touring the star-filled nightscapes of southwest Saskatchewan.
On their license plates Saskatchewan is billed as the Land of Living Skies. I like the moniker that Saskatchewan singer-songwriter Connie Kaldor gives it – the sky with nothing to get in the way.
Grasslands National Park should be a mecca for all stargazers. It is a Dark Sky Preserve. You can be at sites in the Park and not see a light anywhere, even in the far distance on the horizon, and barely any sky glows from manmade sources.
The lead image shows the potential for camping in the Park under an amazing sky, an attraction that is drawing more and more tourists to sites like Grasslands.
This is a multi- panel panorama of the Milky Way over the historic 76 Ranch Corral in the Frenchman River Valley, once part of the largest cattle ranch in Canada. Mars shines brightly to the east of the galactic core.

Illumination is by starlight. No light painting was employed here. This is a stack of 8 exposures for the ground, mean combined to smooth noise, and a single untracked exposure for the sky, all 30 seconds at f/2.8 with the Sigma 20mm lens, and Nikon D750 at ISO 6400 with LENR on.
Mars (at left) and the Milky Way (at right) over a single tipi (with another under construction at back) at the Two Trees site at Grasslands National Park, Saskatchewan, August 6, 2018. I placed a low-level warm LED light inside the tipi for the illumination. This is a stack of 6 exposures, mean combined to smooth noise, for the ground, and one untracked exposure for the sky, all 30 seconds at f/2.2 with the 20mm Sigma lens and Nikon D750 at ISO 3200.
The Big Dipper and Arcturus (at left) over a single tipi at the Two Trees site at Grasslands National Park, Saskatchewan, August 6, 2018. This is a stack of 10 exposures, mean combined to smooth noise, for the ground, and one untracked exposure for the sky, all 30 seconds at f/2.8 with the 20mm Sigma lens and Nikon D750 at ISO 6400. Light cloud passing through added the natural star glows, enlarging the stars and making the pattern stand out. No soft focus filter was employed, and illumination is from starlight. No light painting was employed. Some airglow and aurora colour the sky. A Glow filter from ON1 Photo Raw applied to the sky to further soften the sky.
At the Two Trees site visitors can stay in the tipis and enjoy the night sky. No one was there the night I was shooting. The night was warm, windless, and bug-less. It was a perfect summer evening.
From Grasslands I headed west to the Cypress Hills along scenic backroads. The main Meadows Campground in Cypress Hills Interprovincial Park, another Dark Sky Preserve, is home every year to the Saskatchewan Summer Star Party. About 350 stargazers and lovers of the night gather to revel in starlight.
The Perseid meteor shower over the Saskatchewan Summer Star Party, on August 10, 2018, with an aurora as a bonus. The view is looking north with Polaris at top centre, and the Big Dipper at lower left. The radiant point in Perseus is at upper right. The sky also has bands of green airglow, which was more prominent in images taken earlier before the short-lived aurora kicked up. The aurora was not obvious to the naked eye. However, the northern sky was bright all night with the airglow and faint aurora. This is a composite of 10 images, one for the base sky with the aurora and two faint Perseids, and 9 other images, each with Perseids taken over a 3.3 hour period, being the best 9 frames with meteors out of 360. Each exposure was 30 seconds at f/2 with the 15mm Laoawa lens and Sony a7III at ISO 4000. I rotated all the additional meteor image frames around Polaris to align the frames to the base sky image, so that the added meteors appear in the sky in the correct place with respect to the background stars, retaining the proper perspective of the radiant point.
A Perseid meteor streaks down the Milky Way over the Saskatchewan Summer Star Party in the Cypress Hills of southwest Saskatchewan, at Cypress Hills Interprovincial Park, a Dark Sky Preserve. The Milky Way shines to the south. About 350 stargazers attend the SSSP every year.

This is a single exposure, 25 seconds, with the Laowa 15mm lens at f/2 and Sony a7III camera at ISO 3200.
This year coincided with the annual Perseid meteor shower and we saw lots!
Most nights were clear, and warmer than usual, allowing shirt-sleeve observing. It was a little bit of Arizona in Canada. Everyone enjoyed the experience. I know I did!
SSSP and Cypress Hills are stargazing heaven in Canada.
From Cypress Hills I drove due north to finally, after years of thinking about it, visit the Great Sandhills near Leader, Saskatchewan. Above is a panorama from the “Boot Hill” ridge at the main viewing area.
The Sandhills is not a provincial park but is a protected eco zone, though used by local ranchers for grazing. However, much of the land remains uniquely prairie but with exposed sand dunes among the rolling hills.
There are farm lights in the distance but the sky above is dark and, in the panorama above, colored by twilight and bands of red and green airglow visible to the camera. It’s dark!
In the twilight, from the top of one of the accessible sand dunes, I shot a panorama of the array of four planets currently across the sky, from Venus in the southwest to Mars in the southeast.
This is the kind of celestial scene you can see only where the sky has nothing to get in the way.
If you are looking for a stellar experience under their “living skies,” I recommend Saskatchewan.
Three perfect nights in July provided opportunities to capture the night sky at popular sites in Banff National Park.
When the weather forecast in mid-July looked so promising I made an impromptu trip to Banff to shoot nightscapes and time-lapses under unusually clear skies. Clouds are often the norm in the mountains or, increasingly these days, forest fire smoke in late summer.
But from July 15 to 17 the skies could not have been clearer, except for the clouds that rolled in late on my last night, when I was happy to pack up and get some sleep.
My first priority was to shoot the marvellous close conjunction of the Moon and Venus on July 15. I did so from the Storm Mountain viewpoint on the Bow Valley Parkway, with a cooperative train also coming through the scene at the right time.
This was the view later with the Milky Way and Mars over Bow Valley and Storm Mountain.
The next night, July 16, was one of the most perfect I had ever seen in the Rockies. Crystal clear skies, calm winds, and great lake reflections made for a picture-perfect night at Bow Lake on the Icefields Parkway. Above is a 360° panorama shot toward the end of the night when the galactic centre of the Milky Way was over Bow Glacier.
Streaks of green airglow arc across the south, while to the north the sky is purple from a faint display of aurora.
This is a rare appearance of the unusual STEVE auroral arc on the night of July 16-17, 2018, with a relatively low Kp Index of only 2 to 3. While the auroral arc was visible the ISS made a bright pass heading east. This is a blend of a single 15-second exposure for the sky and ground, with seven 15-second exposures for the ISS, but masked to reveal just the ISS trail and its reflection in the water. The ISS shots were taken at 3-second intervals, thus the gaps. All with the Sigma 20mm Art lens at f/2 and Nikon D750 at ISO 6400. Taken from Bow Lake, Banff National Park, Alberta.
The unusual STEVE auroral arc across the northern sky at Bow Lake, Banff National Park, Alberta on the night of July 16-17, 2018. The more normal green auroral arc is lower across the northern horizon. But STEVE here appears more pink. The STEVE aurora was colourless to the eye but did show faint fast-moving rays, here blurred by the long exposure. They were moving east to west. The Big Dipper is at left. The lights are from Num-Ti-Jah Lodge. This is a single exposure for the sky and a mean-stacked blend of 3 exposures for the ground to smooth noise. All 15 seconds at f/2 with the Sigma 20mm Art lens and Nikon D750 at ISO 6400.
Earlier that night the usual auroral arc known as Steve put in an unexpected appearance. It was just a grey band to the eye, but the camera picked up Steve’s usual pink colours. Another photographer from the U.S. who showed up had no idea there was an aurora happening until I pointed it out.
My last night was at Herbert Lake, a small pond great for capturing reflections of the mountains around Lake Louise, and the Milky Way. Here, brilliant Mars, so photogenic this summer, also reflects in the still waters.
A blend of images to show the stars of the southern sky moving from east to west (left to right) over the peaks of the Continental Divide at Herbert Lake near Lake Louise, in Banff, Alberta. The main peak at left is Mount Temple. A single static image shows the Milky Way and stars at the end of the motion sequence. The star trails and Milky Way reflect in the calm waters of the small Lake Herbert this night on July 17, 2018. This is a stack of 100 images for the star trails, stacked with the Long Streak function of Advanced Stacker Plus actions, plus a single exposure taken a minute or so after the last star trail image. The star trail stack is dropped back a lot in brightness, plus they are blurred slightly, so as to not overwhelm the fixed sky image. The sky images are blended with a stack of 8 images for the ground, mean combined to smooth noise in the ground. All are 30 seconds at f/2.8 with the 24mm Sigma lens and Nikon D750 at ISO 3200. All were taken as part of a time-lapse sequence. Clouds moving in added the odd dark patches in the Milky Way that look like out of place dark nebulas. The reflected star trails are really there in the water and have not be copied, pasted and inverted from the sky image. They look irregular because of rippling in the water.

This is a stack of 8 exposures, mean combined to smooth noise, for the ground, plus 200 exposures for the star trails, and one exposure, untracked, for the fixed sky taken about a minute after the last star trail image. All 30 seconds at f/2.8 with the 24mm Sigma lens, and Nikon D750 at ISO 6400. The frames were taken as part of a time-lapse sequence. Dynamic Contrast filter from ON1 applied to the ground, and Soft and Airy filter from Luminar applied to the sky for a soft Orton effect.
At each site I shot time-lapses, and used those frames to have some fun with star trail stacking, showing the stars turning from east to west and reflected in the lake waters, and with a single still image taken at the end of the sequence layered in to show the untrailed sky and Milky Way.
But I also turned those frames into time-lapse movies, and incorporated them into a new music video, along with some favourite older clips reprocessed for this new video.
Banff by Night (4K) from Alan Dyer on Vimeo.
Enjoy! And do enlarge to full screen. The video is also in 4K resolution.
Clear nights and a waxing Moon made for great opportunities to shoot the Badlands under moonlight.
This has not been a great spring. Only now is the last of the snow melting here in Alberta.
But some mild and clear nights this week with the waxing gibbous Moon allowed me to head to the Red Deer River valley near where I live in Alberta for some moonlit nightscapes.
Here’s the Big Dipper high overhead as it is in spring pointing down to Polaris.
I shot this and some other images in this gallery with the new Sony a7III mirrorless camera. A full test of its astrophoto abilities is in the works.
This is Jupiter rising, with the Moon lighting the sky, and illuminating the landscape. Moonlight is the same colour as sunlight, just much fainter. So while this might look like a daytime scene, it isn’t.
This is Venus setting in the evening twilight at the Hoodoos on Highway 10 near Drumheller. The winter stars are setting into the west, to disappear for a few months.
Here’s Venus in closeup, passing between the Hyades and Pleiades star clusters in Taurus, low in the twilight over the scenic Horsethief Canyon area of the Red Deer River.
While Venus is climbing higher into our evening sky this spring, the Pleiades, Hyades and all the winter stars are fast disappearing from view.
We say goodbye to winter, and not a moment too soon!
Prospects looked bleak for seeing the January 31 total eclipse of the Moon. A little planning, a chase, and a lot of luck made it possible.
A mid-winter eclipse doesn’t bode well. Especially one in the cold dawn hours. Skies could be cloudy. Or, if they are clear, temperatures could be -25° C.
I managed to pull this one off, not just seeing the eclipse of the Moon, but getting a few photos.
The secret was in planning, using some helpful apps …
Starry Night™ / Simulation Curriculum
Because this eclipse was occurring before dawn for western North America the eclipsed Moon was going to be in the west, setting.
To plan any shoot the first app I turn to is the desktop planetarium program Starry Night™.
Shown above, the program simulates the eclipse with the correct timing, accurate appearance, and location in the sky at your site. You can set up indicators for the fields of various lenses, to help you pick a lens. The yellow box shows the field of view of a 50mm lens on my full-frame camera, essential information for framing the scene.
With that information in mind, the plan was to shoot the Moon over the Rocky Mountains, which lie along the western border of Alberta.
The original plan was a site in Banff on the Bow Valley Parkway looking west toward the peaks of the Divide.
But then the next critical information was the weather.
For that I turned to the website ClearDarkSky.com. It uses information from Environment Canada’s Astronomy forecasts and weather maps to predict the likelihood of clouds at your site. The day before the eclipse this is what it showed.
ClearSkyChart
Not good! Home on the prairies was not an option. While Banff looked OK, the best prospects were from farther south in the Crowsnest Pass area of Alberta, as marked. So a chase was in order, involving a half-day drive south.
But what actual site was going to be useful? Where could I set up for the shot I wanted?
I needed a spot off a main highway but drivable to, and with no trees in the way. I did not know the area, but Allison Road looked like a possibility.
The TPE app shows the direction to the Sun and Moon to help plan images by day. And in its night mode it can show where the Milky Way is. Here, the thin blue line is showing the direction to the Moon during totality, showing it to the south of Mt. Tecumseh. I wanted the Moon over the mountains, but not behind a mountain!
With a possible site picked out, it was time to take a virtual drive with Google Earth.
Google Earth Street View
The background map TPE uses is from Google Earth. But the actual Google Earth app also offers the option of a Street View for many locations.
Above is its view from along Allison Road, on the nice summer day when the Google camera car made the drive. But at least this confirms there are no obstructions or ugly elements to spoil the scene, or trees to block the view.
But there’s nothing like being there to be sure. It looks a little different in winter!
Theodolite App
After driving down to the Crowsnest Pass the morning before, the first order of the day upon arrival was to go to the site before it got dark, to see if it was usable.
I used the mobile app Theodolite to take images (above) that superimpose the altitude and azimuth (direction) where the camera was aimed. It confirms the direction where the Moon will be is in open sky to the left of Tecumseh peak. And the on-site inspection shows I can park there!
All set?
There is one more new and very powerful app that provides another level of planning. From The Photographer’s Ephemeris, you can hand off your position to a companion mobile app (for iOS only) called TPE 3D …
TPE 3D with 50mm lens field
It provides elevation maps and places you on site, with the actual skyline around you drawn in. And with the Moon and stars in the sky at their correct positions.
While it doesn’t simulate the actual eclipse, it sure shows an accurate sky … and what you’ll frame with your lens with the actual skyline in place.
Compare the simulation, above, to the real thing, below:
This is a blend of a 15-second exposure for the sky and foreground, and a shorter 1-second exposure for the Moon to prevent its disk from being overexposed, despite it being dim and deep red in totality. Both were at f/2.8 with the 50mm Sigma lens on the Canon 6D MkII at ISO 1600.
Pretty amazing!
Zooming out with TPE 3D provides this preview of a panorama I hoped to take.
TPE 3D zoomed out for 11mm lens simulation
It shows Cassiopeia (the W of stars at right) over the iconic Crowsnest Mountain, and the stars of Gemini setting to the right of Tecumseh.
Here’s the real thing, in an even wider 180° view sweeping from south to north. Again, just as predicted!
The panorama is from 8 segments, each with the 35mm lens at f/2.8 for 15 seconds at ISO 1600 with the Canon 6D MkII. Stitching was with Adobe Camera Raw. The Moon itself is blend of 4 exposures: 15 seconds, 4 seconds, 1 second, and 1/4 second to retain the red disk of the eclipsed Moon while bringing out the stars in the twilight sky.
Between the weather predictions – which proved spot on – and the geographical and astronomical planning apps – which were deadly accurate – we now have incredible tools to make it easier to plan the shot.
If only we could control the clouds! As it was, the Moon was in and out of clouds throughout the 70 minutes of totality. But I was happy to just get a look, let alone a photo.
The next total lunar eclipse is in six months, on July 27, 2018, but in an event visible only from the eastern hemisphere.
The next TLE for North America is a more convenient evening event on January 20, 2019. That will be another winter eclipse requiring careful planning!
To Adobe or not to Adobe. That is the question many photographers are asking with the spate of new image processing programs vying to “kill Photoshop.”
I tested more than ten contenders as alternatives to Adobe’s image processing software, evaluating them ONLY for the specialized task of editing demanding nightscape images taken under the Milky Way, both for single still images and for time-lapses of the moving sky. I did not test these programs for other more “normal” types of images.
Also, please keep in mind, I am a Mac user and tested only programs available for MacOS, though many are also available for Windows. I’ve indicated these.
But I did not test any Windows-only programs. So sorry, fans of Paintshop Pro (though see my note at the end), Photoline, Picture Window Pro, or Xara Photo & Graphic Designer. They’re not here. Even so, I think you will find there’s plenty to pick from!
This review expands upon and updates mini-reviews I included in my Nightscapes and Time-Lapses eBook, shown at right.
If you are hoping there’s a clear winner in the battle against Adobe, one program I can say does it all and for less cost and commitment, I didn’t find one.
However, a number of contenders offer excellent features and might replace at least one member of Adobe’s image processing suite.
For example, only four of these programs can truly serve as a layer-based editing program replacing Photoshop.
The others are better described as Adobe Lightroom competitors – programs that can catalog image libraries and develop raw image files, with some offering adjustment layers for correcting color, contrast, etc. But as with Lightroom, layering of images – to stack, composite, and mask them – is beyond their ability.
For processing time-lapse sequences, however, we don’t need, nor can we use, the ability to layer and mask several images into one composite.
What we need for time-lapses is to:
Develop a single key raw file, then …
Copy its settings to the hundreds of other raw files in the time-lapse set, then …
Export that folder of raw images to “intermediate JPGs” for assembly into a movie.
Even so, not all these contenders are up to the task.
Here are the image processing programs I looked at. Costs are in U.S. dollars. Most have free trial copies available.
The Champion from Adobe
Adobe Camera Raw (ACR), Photoshop, Bridge, and Lightroom, the standards to measure others by
Cost: $10 a month by subscription, includes ACR, Photoshop, Bridge, and Lightroom
Adobe Camera Raw (ACR) is the raw development plug-in that comes with Photoshop and Adobe Bridge, Adobe’s image browsing application that accompanies Photoshop. Camera Raw is equivalent to the Develop module in Lightroom, Adobe’s cataloguing and raw processing software. Camera Raw and Lightroom have identical processing functions and can produce identical results.
Photoshop and Lightroom complement each other and are now available together, but only by monthly subscription through Adobe’s Creative Cloud service, at $10/month. Though $120 for a year is not far off the cost of purchasing many of these other programs and perhaps upgrading them annually, many photographers prefer to purchase their software and not subscribe to it.
Thus the popularity of these alternative programs. Most offered major updates in late 2017.
My question is, how well do they work? Are any serious contenders to replace Photoshop or Lightroom?
Lightroom Contenders: Five Raw Developers
ACDSee Photo Studio (current as of late 2017)
Cost: $60 to $100, depending on version, upgrades $40 to $60.
I tested the single MacOS version. Windows users have a choice of either a Standard or Professional version. Only the Pro version offers the full suite of raw development features, in addition to cataloging functions. The MacOS version resembles the Windows Pro version.
Capture One v11 (late 2017 release)
Cost: $299, and $120 for major upgrades, or by subscription for $180/year
As of version 11 this powerful raw developer and cataloguing program offers “Layers.” But these are only for applying local adjustments to masked areas of an image. You cannot layer different images. So Capture One cannot be used like Photoshop, to stack and composite images. It is a Lightroom replacement only, but a very good one indeed.
Here’s a low cost Lightroom replacement for image management and raw processing abilities. Noise reduction is “Perfectly Clear” from Athentech and works well.
The ELITE version of what DxO now calls “PhotoLab” offers DxO’s superb PRIME noise reduction and excellent ClearView contrast enhancement feature. While it has an image browser, PhotoLab does not create a catalog, so this isn’t a full Lightroom replacement, but it is a superb raw developer. DxO also recently acquired the excellent Nik Collection of image processing plug-ins, so we can expect some interesting additions and features.
This free open source program has been created and is supported by a loyal community of programmers. It offers a bewildering blizzard of panels and controls, among them the ability to apply dark frames and flat field images, features unique among any raw developer and aimed specifically at astrophotographers. Yes, it’s free, but the learning curve is precipitous.
Photoshop Contenders: Four Raw Developers with Layering/Compositing
These programs can not only develop at least single raw images, if not many, but also offer some degree of image layering, compositing, and masking like Photoshop.
However, only ON1 Photo RAW can do that and also catalog/browse images as Lightroom can. Neither Affinity, Luminar, or Pixelmator offer a library catalog like Lightroom, nor even a file browsing function such as Adobe Bridge, serious deficiencies I feel.
This is the lowest cost raw developer and layer-based program on offer here, and has some impressive features, such as stacking images, HDR blending, and panorama stitching. However, it lacks any library or cataloguing function, so this is not a Lightroom replacement, but it could replace Photoshop.
Macphun has changed their name to Skylum and now makes their fine Luminar program for both Mac and Windows. While adding special effects is its forte, Luminar does work well both as a raw developer and layer-based editor. But like Affinity, it has no cataloguing feature. It cannot replace Lightroom.
Of all the contenders tested here, this is the only program that can truly replace both Lightroom and Photoshop, in that ON1 has cataloguing, raw developing, and image layering and masking abilities. In fact, ON1 allows you to migrate your Lightroom catalog into its format. However, ON1’s cost to buy and maintain is similar to Adobe’s Creative Cloud Photo subscription plan. It’s just that ON1’s license is “perpetual.”
NOTE: Windows users might find Corel’s Paintshop Pro 2018 a good “do-it-all” solution – I tested only Corel’s raw developer program Aftershot Pro, which Paintshop Pro uses.
The “Pro” version of Pixelmator was introduced in November 2017. It has an innovative interface and many fine features, and it allows layering and masking of multiple images. However, it lacks some of the key functions (listed below) needed for nightscape and time-lapse work. Touted as a Photoshop replacement, it isn’t there yet.
The Challenge
This is the image I threw at all the programs, a 2-minute exposure of the Milky Way taken at Writing-on-Stone Provincial Park in southern Alberta in late July 2017.
NOTE: Click/tap on any of the screen shots to bring them up full screen so you can inspect and save them.
Original Raw Image Out of the Camera, BEFORE Development
The lens was the Sigma 20mm Art lens at f/2 and the camera the Nikon D750 at ISO 1600.
Thus the ground is blurred. Keep that in mind, as it will always look fuzzy in the comparison images. But it does show up noise well, including hot pixels. This image of the sky is designed to be composited with one taken without the tracker turning, to keep the ground sharp.
Raw Image AFTER Development in Adobe Camera Raw
Above is the image after development in Adobe Camera Raw (ACR), using sliders under its Basic, Tone Curve, Detail, HSL, Lens Corrections, and Effects tabs. Plus I added a “local adjustment” gradient to darken the sky at the top of the frame. I judged programs on how well they could match or beat this result.
Same Image Developed in Adobe Lightroom
Above is the same image developed in Adobe Lightroom, to demonstrate how it can achieve identical results to Camera Raw, because at heart it is Camera Raw.
Feature Focus
I have assumed a workflow that starts with raw image files from the camera, not JPGs, for high-quality results.
And I have assumed the goal of making that raw image look as good as possible at the raw stage, before it goes to Photoshop or some other bit-mapped editor. That’s an essential workflow for time-lapse shooting, if not still-image nightscapes.
However, I made no attempt to evaluate all these programs for a wide range of photo applications. That would be a monumental task!
Nor, in the few programs capable of the task, did I test image layering. My focus was on developing a raw image. As such, I did not test the popular free program GIMP, as it does not open raw files. GIMP users must turn to one of the raw developers here as a first stage.
If you are curious how a program might perform for your purposes and on your photos, then why not test drive a trial copy?
Instead, my focus was on these programs’ abilities to produce great looking results when processing one type of image: my typical Milky Way nightscape, below.
TIFF Exported from DxO PhotoLab … then Imported into Photoshop
Such an image is a challenge because…
The subject is inherently low in contrast, with the sky often much brighter than the ground. The sky needs much more contrast applied, but without blocking up the shadows in the ground.
The sky is often plagued by off-color tints from artificial and natural sky glows.
The ground is dark, perhaps lit only by starlight. Bringing out landscape details requires excellent shadow recovery.
Key to success is superb noise reduction. Images are shot at high ISOs and are rife with noise in the shadows. We need to reduce noise without losing stars or sharpness in the landscape.
I focused on being able to make one image look as good as possible as a raw file, before bringing it into Photoshop or a layer-based editor – though that’s where it will usually end up, for stacking and compositing, as per the final result shown at the end.
I then looked at each program’s ability to transfer that one key image’s settings over to what could be hundreds of other images taken that night, either for stacking into star trails or for assembling into a time-lapse movie.
Summary Conclusions
Results of 8 Programs compared to ACR (at left)
None of the programs I tested ticked all the boxes in providing all the functions and image quality of the Adobe products.
But here’s a summary of my recommendations:
For Advanced Time-Lapse
None of the non-Adobe programs will work with the third-party software LRTimelapse (www.lrtimelapse.com). It is an essential tool for advanced time-lapse processing. LRTimelapse works with Lightroom or ACR/Bridge to gradually shift processing settings over a sequence, and smooth annoying image flickering.
If serious and professional time-lapse shooting is your goal, none of the Adobe contenders will work. Period. Subscribe to Creative Cloud. And buy LRTimelapse.
For Basic Time-Lapse
However, for less-demanding time-lapse shooting, when the same settings can be applied to all the images in a sequence, then I feel the best non-Adobe choices are, in alphabetical order:
ACDSee
Capture One
Corel Aftershot Pro
DxO PhotoLab
ON1 Photo RAW
… With, in my opinion, DxO and Capture One having the edge for image quality and features. But all five have a Library or Browser mode with easy-to-use Copy & Paste and Batch Export functions needed for time-lapse preparation.
Also worth a try is PhotoDirector9 (MacOS and Windows), a good Lightroom replacement. Scroll to the end for more details and a link.
For Still Image Nightscapes
If you are processing just individual still images, perhaps needing only to stack or composite a few exposures, and want to do all the raw development and subsequent layering of images within one non-Adobe program, then look at (again alphabetically):
Affinity Photo
Luminar 2018
ON1 Photo RAW 2018
… With Affinity Photo having the edge in offering a readily-available function off its File menu for stacking images, either for noise smoothing (Mean) or creating star trails (Maximum).
However, I found its raw development module did not produce as good a result as most competitors due to Affinity’s poorer noise reduction and less effective shadow and highlight controls. Using Affinity’s “Develop Persona” module, I could not make my test image look as good as with other programs.
Luminar 2018 has better noise reduction but it demands more manual work to stack and blend images.
While ON1 Photo Raw has some fine features and good masking tools, it exhibits odd de-Bayering artifacts, giving images a cross-hatched appearance at the pixel-peeping level. Sky backgrounds just aren’t smooth, even after noise reduction.
To go into more detail, these are the key factors I used to compare programs.
Noise Reduction
Absolutely essential is effective noise reduction, of luminance noise and chrominance color speckles and splotches.
Ideally, programs should also have a function for suppressing bright “hot” pixels and dark “dead” pixels.
Here’s what I consider to be the “gold standard” for noise reduction, Adobe Camera Raw’s result using the latest processing engine in ACR v10/Photoshop CC 2018.
BEFORE and AFTER Noise Reduction with Adobe Camera Raw (ACR)
I judged other programs on their ability to produce results as good as this, if not better, using their noise reduction sliders. Some programs did better than others in providing smooth, noiseless skies and ground, while retaining detail.
BEFORE and AFTER Noise Reduction and Other Adjustments with DxO PhotoLab
For example, one of the best was DxO PhotoLab, above. It has excellent options for reducing noise without being overwhelming in its choices, the case with a couple of other programs. For example, DxO has a mostly effective dead/hot pixel removal slider.
ACR does apply such a hot pixel removal “under the hood” as a default, but often still leaves many glaring hot specks that must be fixed later in Photoshop.
Comparing Noise Reduction
300% Close-Ups to Compare Noise Reduction
Above are 8 of the contender programs compared to Camera Raw for noise reduction.
Missing from this group is the brand new Pixelmator Pro, for MacOS only. It does not yet have any noise reduction in its v1 release, a serious deficiency in imaging software marketed as “Pro.” For that reason alone, I cannot recommend it. I describe its other deficiencies below.
Lens Corrections
The wide-angle lenses we typically use in nightscape and time-lapse imaging suffer from vignetting and lens distortions. Having software that can automatically detect the lens used and apply bespoke corrections is wonderful.
Lens Corrections in Capture One
Only a few programs, such as Capture One (above), have a library of camera and lens data to draw upon to apply accurate corrections with one click. With others you have to dial in corrections manually by eye, which is crude and inaccurate.
Shadows and Highlights
All programs have exposure and contrast adjustments, but the key to making a Milky Way nightscape look good is being able to boost the shadows (the dark ground) while preventing the sky from becoming overly bright, yet while still applying good contrast to the sky.
Shadows and Highlight and other Enhancements in DxO PhotoLab
Of the contenders, I liked DxO PhotoLab best (shown above), not only for its good shadow and highlight recovery, but also excellent “Smart Lighting” and “ClearView” functions which served as effective clarity and dehaze controls to snap up the otherwise low-contrast sky. With most other programs it was tough to boost the shadows without also flattening the contrast.
On the other hand, Capture One’s excellent layering and local adjustments did make it easier to brush in adjustments just to the sky or ground.
However, any local adjustments like those will be feasible only for still images or time-lapses where the camera does not move. In any motion control sequences the horizon will be shifting from frame to frame, making precise masking impractical over a sequence of hundreds of images.
Therefore, I didn’t place too much weight on the presence of good local adjustments. But they are nice to have. Capture One, DxO PhotoLab, and ON1 win here.
Selective Color Adjustments
All programs allow tweaking the white balance and overall tint.
But it’s beneficial to also adjust individual colors selectively, to enhance red nebulas, enhance or suppress green airglow, bring out green grass, or suppress yellow or orange light pollution.
Some programs have an HSL panel (Hue, Saturation, Lightness) or an equalizer-style control for boosting or dialing back specific colors.
Color Adjustments in Capture One
Capture One (above) has the most control over color correction, with an impressive array of color wheels and sliders that can be set to tweak a broad or narrow range of colors.
And yet, despite this, I was still unable to make my test image look quite the way I wanted for color balance. ACR and DxO PhotoLab still won out for the best looking final result.
Copy and Paste Settings
Even when shooting nightscape stills we often take several images to stack later. It’s desirable to be able to process just one image, then copy and paste its settings to all the others in one fell swoop. And then to be able to inspect those images in thumbnails to be sure they all look good.
Some programs (Affinity Photo, Luminar, Pixelmator Pro) lack any library function for viewing or browsing a folder of thumbnail images. Yes, you can export a bunch of images with your settings applied as a user preset, but that’s not nearly as good as actually seeing those images displayed in a Browser mode.
Copy and Paste Settings in ON1 Photo RAW
What’s ideal is a function such as ON1 Photo RAW displays here, and that some other programs have: the ability to inspect a folder of images, work on one, then copy and paste its settings to all the others in the set.
This is absolutely essential for time-lapse work, and nice to have even when working on a small set to be stacked into a still image.
Batch Export
Once you develop a folder of raw images with “Copy and Paste,” you now have to export them with all those settings “baked into” the exported files.
This step is to create an intermediate set of JPGs to assemble into a movie. Or perhaps to stack into a star trail composite using third party software such as StarStaX, or to work on the images in another layer-based program of your choice.
Batch Export in ON1 Photo RAW
As ON1 Photo RAW shows above, this is best done using a Library or Browser mode to visually select the images, then call up an Export panel or menu to choose the image size, format, quality, and location for the exports.
Click Export and go for coffee – or a leisurely dinner – while the program works through your folder. All programs took an hour or more to export hundreds of images.
Design
Those functions were the key features I looked for when evaluating the programs for nightscape and time-lapse work.
Every program had other attractive features, often ones I wished were in Adobe Camera Raw. But if the program lacked any of the above features, I judged it unsuitable.
Yes, the new contenders to the Photoshop crown have the benefit of starting from a blank slate for interface design.
Luminar 2018’s Clean User Interface
Many, such as Luminar 2018 above, have a clean, attractive design, with less reliance on menus than Photoshop.
Photoshop has grown haphazardly over 25 years, resulting in complex menus. Just finding key functions can take many tutorial courses!
But Adobe dares to “improve” Photoshop’s design and menu structure at its peril, as Photoshop fans would scream if any menus they know and love were to be reorganized!
The new mobile-oriented Lightroom CC is Adobe’s chance to start afresh with a new interface.

Program-by-Program Results
I could end the review here, but I feel it’s important to present the evidence, in the form of screen shots of all the programs, showing both the whole image, and a close-up to show the all-important noise reduction.
ACDSee Photo Studio
ACDSee Full Screen
ACDSee Enlargement
PROS: This capable cataloging program has good selective color and highlight/shadow recovery, and pretty smooth noise reduction. It can copy and paste settings and batch export images, for time-lapses. It is certainly affordable, making it a low-cost Lightroom contender.
CONS: It lacks any gradient or local adjustments, or even spot removal brushes. Lens corrections are just manual. There is no dehaze control, which can be useful for snapping up even clear night skies. You cannot layer images to create composites or image stacks. This is not a Photoshop replacement.
Affinity Photo
Affinity Photo Full Screen
Affinity Photo Enlargement
PROS: Affinity supports image layers, masking with precise selection tools, non-destructive “live” filters (like Photoshop’s Smart Filters), and many other Photoshop-like functions. It has a command for image stacking with a choice of stack modes for averaging and adding images.
It’s a very powerful but low cost alternative to Photoshop, but not Lightroom. It works fine when restricted to working on just a handful of images.
CONS: Affinity has no lens correction database, and I found it hard to snap up contrast in the sky and ground without washing them out, or having them block up. Raw noise reduction was acceptable but not up to the best for smoothness. It produced a blocky appearance. There are no selective color adjustments.
Nor is there any library or browse function. You can batch export images, but only through an unfriendly dialog box that lists images only by file name – you cannot see them. Nor can you copy and paste settings visually, but only apply a user-defined “macro” to develop images en masse upon export.
This is not a program for time-lapse work.
Capture One 11
Capture One 11 Full Screen
Capture One 11 Enlargement
PROS: With version 11 Capture One became one of the most powerful raw developers, using multiple layers to allow brushing in local adjustments, a far better method than Adobe Camera Raw’s local adjustment “pins.” It can create a catalog from imported images, or images can be opened directly for quick editing. Its noise reduction was good, with hot pixel removal lacking in Camera Raw.
Its color correction options were many!
It can batch export images. And it can export files in the raw DNG format, though in tests only Adobe Camera Raw was able to read the DNG file with settings more or less intact.
CONS: It’s costly to purchase, and more expensive than Creative Cloud to subscribe to. Despite all its options I could never quite get as good looking an image using Capture One, compared to DxO PhotoLab for example.
It is just a Lightroom replacement; it can’t layer images.
Corel Aftershot Pro 3
Corel Aftershot Pro Full Screen
Corel Aftershot Pro Enlargement
PROS: This low-cost option has good noise reduction using Athentech’s Perfectly Clear process, with good hot pixel or “impulse” noise removal. It has good selective color and offers adjustment layers for brushing in local corrections. And its library mode can be used to copy and paste settings and batch export images.
Again, it’s solely a Lightroom alternative.
CONS: While it has a database of lenses, and identified my lens, it failed to apply any automatic corrections. Its shadow and highlight recovery never produced a satisfactory image with good contrast. Its local adjustment brush is very basic, with no edge detection.
DxO PhotoLab
DxO PhotoLab Full Screen
DxO PhotoLab Enlargement
PROS: I found DxO produced the best looking image, better perhaps than Camera Raw, because of its DxO ClearView and Smart Lighting options. It has downloadable camera and lens modules for automatic lens corrections. Its noise reduction was excellent, with its PRIME option producing by far the best results of all the programs, better perhaps than Camera Raw, plus with hot pixel suppression.
DxO has good selective color adjustments, and its copy and paste and batch export work fine.
CONS: There are no adjustment layers as such. Local adjustments and repairing are done through the unique U-Point interface which works something like ACR’s “pins,” but isn’t as visually intuitive as masks and layers. Plus, DxO is just a raw developer; there is no image layering or compositing. Nor does it create a catalog as such.
So it is not a full replacement for either Lightroom or Photoshop. But it does produce great looking raw files for export (even as raw DNGs) to other programs.
Luminar 2018
Luminar 2018 Full Screen
Luminar 2018 Enlargement
PROS: Luminar has good selective color adjustments, a dehaze control, and good contrast adjustments for highlights, mid-tones, and shadows. Adjustments can be added in layers, making them easier to edit. Noise reduction was smooth and artifact-free, but adjustments were basic. Many filters can be painted on locally with a brush, or with a radial or gradient mask.
CONS: It has no lens correction database; all adjustments are manual. The preview was slow to refresh and display results when adjusting filters. The interface is clean but always requires adding filters to the filter panel to use them when creating new layers. Its batch export is crude, with only a dialog box and no visual browser to inspect or select images.
Settings are applied as a user preset on export, not through a visual copy-and-paste function. I don’t consider that method practical for time-lapses.
ON1 Photo RAW 2018
ON1 Photo RAW Full Screen
ON1 Photo RAW Enlargement
PROS: ON1 is the only program of the bunch that can: catalog images, develop raw files, and then layer and stack images, performing all that Lightroom and Photoshop can do. It is fast to render previews in its “Fast” mode, but in its “Accurate” mode ON1 is no faster than Lightroom. It has good layering and masking functions, both in its Develop mode and in its Photoshop-like Layers mode.
Selective color and contrast adjustments were good, as was noise reduction. Developing, then exporting a time-lapse set worked very well, but still took as long as with Lightroom or Photoshop.
CONS: Despite promising automatic lens detection and correction, ON1 failed to apply any vignetting correction for my 20mm Sigma lens. Stars exhibited dark haloes, even with no sharpening, dehaze, or noise reduction applied. Its de-Bayering algorithm produced a cross-hatched pattern at the pixel level, an effect not seen on other programs.
Noise reduction did not smooth this. Thus, image quality simply wasn’t as good.

Pixelmator Pro Enlargement
PROS: It is low cost. And it has an attractive interface.
CONS: As of version 1 released in November 2017 Pixelmator Pro lacks: any noise reduction (it’s on their list to add!), any library mode or copy and paste function, nor even the ability to open several images at once displayed together.
It is simply not a contender for “Photoshop killer” for any photo application, despite what click-bait “reviews” promise, ones that only re-write press releases and don’t actually test the product.
Raw Therapee v5.3

Raw Therapee Enlargement – With and Without Noise Reduction
PROS: It’s free! It offers an immense number of controls and sliders. You can even change the debayering method. It detects and applies lens corrections (though in my case only distortion, not vignetting). It has good selective color with equalizer-style sliders. It has acceptable (sort of!) noise reduction and sharpening with a choice of methods, and with hot and dead pixel removal.
It can load and apply dark frames and flat fields, the only raw developer software that can. This is immensely useful for deep-sky photography.
CONS: It offers an immense number of controls and sliders! Too many! It is open source software by committee, with no one in charge of design or user friendliness. Yes, there is documentation, but it, too, is a lot to wade through to understand, especially with its broken English translations. This is software for digital signal processing geeks.
But worst of all, as shown above, its noise reduction left lots of noisy patches in shadows, no matter what combination of settings I applied. Despite all its hundreds of sliders, results just didn’t look as good.
What About …? (updated December 28)
No matter how many programs I found to test, someone always asks, “What about …?” In some cases such comments pointed me to programs I wasn’t even aware of, but subsequently tried out. So here are even more to pick from…
Billed as having “everything you need in an image editor,” this low-cost ($30) MacOS-only program is anything but. Its raw developer module is crude and lacks any of the sophisticated range of adjustments offered by all the other programs on offer here. It might be useful as a layer-based editor of images developed by another program.
Available for Mac and Windows for $150, this Lightroom competitor offers a good browser function, with the ability to “copy-from-one and paste-to-many” images (unlike some of the programs below), and a good batch export function for time-lapse work. It has good selective color controls and very good noise reduction providing a smooth background without artifacts like blockiness or haloes. Local adjustments, either through brushed-on adjustments or through gradients, are applied via handy and easy to understand (I think!) layers.
While it has auto lens corrections, its database seemed limited — it did not have my Sigma 20mm lens despite it being on the market for 18 months. Manual vignetting correction produced a poor result with just a washed out look.
The main issue was that its shadow, highlight, and clarity adjustments just did not produce the snap and contrast I was looking for, but that other programs could add to raw files. Still, it looks promising, and is worth a try with the trial copy. You might find you like it. I did not. For similar cost, other programs did a better job, notably DxO PhotoLab.
In the same ilk as Raw Therapee, I also tested out another free, open-source raw developer, one simply called “darktable,” with v2.2.5 shown below. While it has some nice functions and produced a decent result, it took a lot of time and work to use.
darktable RAW Developer
The MacOS version I tried (on a brand new 5K iMac) ran so sluggishly, taking so long to re-render screen previews, that I judged it impractical to use. Sliders were slow to move and when I made any adjustments often many seconds would pass before I would see the result. Pretty frustrating, even for free.
A similar crowd-developed raw processing program, Iridient Developer (above), sells for $99 US. I tested a trial copy of v3.2. While it worked OK, I was never able to produce a great looking image with it. It had no redeeming features over the competition that made its price worthwhile.
Paintshop Pro’s included but very basic Raw developer.
Using Parallels running Windows 10 on my Mac, I did try out this popular Windows-only program from Corel. By itself, Paintshop Pro’s raw developer module (shown above) is basic, crude and hardly up to the tax of processing demanding raw files. You are prompted to purchase Corel’s Aftershot Pro for more capable raw development, and I would agree – Aftershot would be an essential addition. However …
As I showed above, I did test the MacOS version of Aftershot Pro on my raw sample image, and found it did the poorest job of making my raw test image look good. Keep in mind that it is the ability of all these programs to develop this typical raw nightscape image that I am primarily testing.
That said, given a well-developed raw file, Paintshop Pro can do much more with it, such as further layering of images and applying non-destructive and masked adjustment layers, as per Photoshop. Indeed, it is sold as a low-cost (~ $60) Photoshop replacement. As such, many Windows users find Paintshop’s features very attractive. However, Paintshop lacks the non-destructive “smart” filters, and the more advanced selection and masking options offered by Photoshop, Affinity Photo, and ON1 Photo Raw. If you have never used these, you likely don’t realize what you are missing.
If it’s an Adobe alternative you are after, I would suggest Windows users would be better served by other options. Why not test drive Affinity and ON1?
PhotoDirector’s very Lightroom-like interface and controls.
This was a surprising find. Little known, certainly to me, this Windows and MacOS program from the Taiwanese company Cyberlink, is best described as a Lightroom substitute, but it’s a good one. Its regular list price is $170. I bought it on sale for $60.
Like Lightroom, working on any images with PhotoDirector requires importing them into a catalog. You cannot just browse to the images. Fine. But one thing some people complain about with Lightroom is the need to always import images.
I was impressed with how good a job PhotoDirector did on my raw test image. PhotoDirector has excellent controls for shadow and highlight recovery, HSL selective color, copying-and-pasting settings, and batch exporting. So it will work well for basic time-lapse processing.
Noise reduction was very good and artifact-free. While it does have automatic lens corrections, its database did not include the 2-year old Sigma 20mm Art lens I used. So it appears its lens data is not updated frequently.
PhotoDirector has good local adjustments and gradients using “pins” rather than layers, similar to Camera Raw and Lightroom.
After performing raw image “Adjustments,” you can take an image into an Edit module (for adding special effects), then into a Layers module for further work. However, doing so destructively “flattens” the image to apply the raw adjustments you made. You cannot go back and tweak the raw settings in the Adjustment module, as you can when opening a raw file as a “smart object” in Adobe Photoshop.
While PhotoDirector does allow you to layer in other images to make basic composites (such as adding type or logos), there is no masking function nor any non-destructive adjustment layers. So this is most assuredly not a Photoshop substitute, despite what the advertising might suggest. But if it’s a Lightroom replacement you are after, do check it out in a trial copy.
MacOS-only Picktorial v3, with its clean interface
This little-known MacOS-only program (only $40 on sale) for developing raw images looks very attractive, with good selective color, lots of local adjustments, and good masking tools, the features promoted on the website. It does have a browse function and can batch export a set of developed files.
However … its noise reduction was poor, introducing glowing haloes around stars when turned up to any useful level. Its shadows, highlights, and contrast adjustments were also poor – it was tough to make the test image look good without flattening contrast or blocking up shadows. Boosting clarity even a little added awful dark haloes to stars, making this a useless function. It has no lens correction, either automatic or manual. Like Topaz Studio, below, it cannot copy and paste settings to a batch of images, only to one image at a time, so it isn’t useful for time-lapse processing.
I cannot recommend this program, no matter how affordable it might be.
Popular among some camera manufacturers as their included raw developer, Silky Pix can be purchased separately ($80 list price for the standard version, $250 list price for the Pro version) with support for many cameras’ image files. It is available for MacOS and Windows. I tried the lower-cost “non-Pro” version 8. It did produce a good-looking end result, with good shadow and highlight recovery, and excellent color controls. Also on the plus side, Silky Pix has very good copy-and-paste functions for development settings, and good batch export functions, so it can be used to work on a folder of time-lapse frames.
On the down side, noise reduction, while acceptable, left an odd mottled pattern, hardly “silky.” The added “Neat” noise reduction option only smoothed out detail and was of little value except perhaps for very noisy images. Noise reduction did nothing to remove hot pixels, leaving lots of colored specks across the image. The program uses unorthodox controls whose purposes are not obvious. Instead of Highlights and Shadows you get Exposure Bias and HDR. Instead of Luminance and Color noise reduction, you get sliders labeled Smoothness and Color Distortion. You really need to read the extensive documentation to learn how to use this program.
I found sliders could be sticky and not easy to adjust precisely. The MacOS version was slow, often presenting long bouts of spinning beachballs while it performed some function. This is a program worth a try, and you might find you like it. But considering what the competition offers, I would not recommend it.
While Topaz Labs previously offered only plug-ins for Photoshop and other programs (their Topaz DeNoise 6 is very good), their Topaz Studio stand-alone program now offers full raw processing abilities.
It is for Mac and Windows. While it did a decent job developing my test Milky Way image (above), with good color and contrast adjustments, it cannot copy and paste settings from one image to a folder of images, only to one other image. Nor can it batch export a folder of images. Both deficiencies make it useless for time-lapse work.
In addition, while the base program is free, adding the “Pro Adjustments” modules I needed to process my test image (Noise Reduction, Dehaze, Precision Contrast, etc.) would cost $160 – each Adjustment is bought separately. Some users might like it, but I wouldn’t recommend it.
And … Adobe Photoshop Elements v18 (late 2017 release)
What about Adobe’s own Photoshop “Lite?” Elements is available for $99 as a boxed or downloadable one-time purchase, but with annual updates costing about $50. While it offers image and adjustment layers, it cannot do much with 16-bit images, and has very limited functions for developing raw files.
And its Lightroom-like Organizer module does not have any copy-and-paste settings or batch export functions, making it unsuitable for time-lapse production.
Photoshop Elements v18 – Showing its Version of Camera Raw Lite
Elements is for processing photos for the snapshot family album. Like Apple’s Photos and other free photo apps, I don’t consider Elements to be a serious option for nightscape and time-lapse work. But it can be pressed into service for raw editing and layering single images, especially by beginners.
However, a Creative Cloud Photo subscription doesn’t cost much more than buying, then upgrading Elements outright, yet gets you far, far more in professional-level software.
And Yet More…!
In addition, for just developing raw files, you likely already have software to do the job – the program that came with your camera.
Canon Digital Photo Professional v4
For Canon it’s Digital Photo Professional (shown above); for Nikon it’s Capture NX; for Pentax it’s Digital Camera Utility, etc.
These are all capable raw developers, but have no layering capabilities. And they read only the files from their camera brand. If theirs is the only software you have, try it. They are great for learning on.
But you’ll find that the programs from other companies offer more features and better image quality.
What Would I Buy?
Except for Capture One, which I tested as a trial copy, I did buy all the software in question, for testing for my Nightscapes eBook.
However, as I’ve described, none of the programs tick all the boxes. Each has strengths, but also weaknesses, if not outright deficiencies. I don’t feel any can fully replace Adobe products for features and image quality.
A possible non-Adobe combination for the best image quality might be DxO PhotoLab for raw developing and basic time-lapse processing, and Affinity Photo for stacking and compositing still images, from finished TIFF files exported out of DxO and opened and layered with Affinity.
But that combo lacks any cataloging option. For that you’d have to add ACDSee or Aftershot for a budget option. It’s hardly a convenient workflow I’d want to use.
ON1 De-Bayer Artifacts (Right) Compared to DxO PhotoLab (Left), at 400%
I’d love to recommend ON1 Photo RAW more highly as a single solution, if only it had better raw processing results, and didn’t suffer from de-Bayering artifacts (shown in a 400% close-up above, compared to DxO PhotoLab). These add the star haloes and a subtle blocky pattern to the sky, most obvious at right.
To Adobe or Not to Adobe
I’m just not anxious, as others are, to “avoid Adobe.”
I’ve been a satisfied Creative Cloud subscriber for several years, and view the monthly fee as the cost of doing business. It’s much cheaper than the annual updates that boxed Photoshop versions used to cost. Nor am I worried about Adobe suddenly jacking up the fees or holding us hostage with demands.
LRTimelapse at Work on a Time-Lapse Sequence
For me, the need to use LRTimelapse (shown above) for about 80 percent of all the time-lapse sequences I shoot means the question is settled. LRTimelapse works only with Adobe software, and the combination works great. Sold.
I feel Camera Raw/Lightroom produces results that others can only just match, if that.
Only DxO PhotoLab beat Adobe for its excellent contrast enhancements and PRIME noise reduction.
Yes, other programs certainly have some fine features I wish Camera Raw or Lightroom had, such as:
Hot and dead pixel removal
Dark frame subtraction and flat field division
Better options for contrast enhancement
And adding local adjustments to raw files via layers, with more precise masking tools
Among others!
But those aren’t “must haves.”
Using ACR or Lightroom makes it easy to export raw files for time-lapse assembly, or to open them into Photoshop for layering and compositing, usually as “smart objects” for non-destructive editing, as shown below.
Final Layered Photoshop Image
Above is the final layered image, consisting of:
A stack of 4 tracked exposures for the sky (the test image is one of those exposures)
And 4 untracked exposures for the ground.
The mean stacking smooths noise even more. The masking reveals just the sky on the tracked set. Every adjustment layer, mask, and “smart filter” is non-destructive and can be adjusted later.
I’ll work on recreating this same image with the three non-Adobe programs capable of doing so – Affinity, Luminar, and ON1 Photo RAW – to see how well they do. But that’s the topic of a future blog.
Making the Switch?
The issue with switching from Adobe to any new program is compatibility.
While making a switch will be fine when working on all new images, reading the terabytes of old images I have processed with Adobe software (and being able to re-adjust their raw settings and layered adjustments) will always require that Adobe software.
If you let your Creative Cloud subscription lapse, as I understand it the only thing that will continue to work is Lightroom’s Library module, allowing you to review images only. You can’t do anything to them.
None of the contender programs will read Adobe’s XMP metadata files to display raw images with Adobe’s settings intact.
Conversely, nor can Adobe read the proprietary files and metadata other programs create.
With final layered Photoshop files, while some programs can read .PSD files, they usually open them just as flattened images, as ON1 warns it will do above. It flattened all of the non-destructive editing elements created in Photoshop. Luminar did the same.
A Layered Photoshop PSB File Opened in Affinity Photo
Only Affinity Photo (above) successfully read a complex and very large Photoshop .PSB file correctly, honouring at least its adjustment and image layers. So, if backwards compatibility with your legacy Photoshop images is important, choose Affinity Photo.
However, Affinity flattened Photoshop’s smart object image layers and their smart filters. Even Adobe’s own Photoshop Elements doesn’t honor smart objects.
Lest you think that’s a “walled garden” created by “evil Adobe,” keep in mind that the same will be true of the image formats and catalogs that all the contender programs produce.
To read the adjustments, layers, and “live filters” you create using any another program, you will need to use that program.
Will Affinity, DxO, Luminar, ON1, etc. be around in ten years?
Yes, you can save out flattened TIFFs that any program can read in the future, but that rules out using those other programs to re-work any of the image’s original settings.
In Conclusion!
U-Point Local Adjustments in DxO PhotoLab
I can see using DxO PhotoLab (above) or Raw Therapee for some specific images that benefit from their unique features.
Or using ACDSee as a handy image browser.
Luminar 2018 as a Plug-In Within Photoshop
And ON1 and Luminar have some lovely effects that can be applied by calling them up as plug-ins from within Photoshop, and applied as smart filters. Above, I show Luminar working as a plug-in, applying its “Soft & Airy” filter.
In the case of Capture One and DxO PhotoLab, their ability to save images back as raw DNG files (the only contender programs of the bunch that can), means that any raw processing program in the future should be able to read the raw image.
DNG Raw File Created by Capture One Opened in ACR
However, only Capture One’s Export to DNG option produced a raw file readable and editable by Adobe Camera Raw with its settings from Capture One (mostly) intact (as shown above).
Even so, I won’t be switching away from Adobe any time soon.
But I hope my survey has given you useful information to judge whether you should make the switch. And if so, to what program.
It takes a dark spring night to see it well, but now lurking near Jupiter is a ghostly sky glow called Gegenschein.
This diffuse glow lies directly opposite the Sun. It is caused by sunlight reflecting off interplanetary dust particles in the outer solar system. They reflect light more effectively at the anti-Sun point where each dust particle is fully lit by the Sun.
Like the Sun, the Gegenschein moves around the sky along the ecliptic, moving about a degree from west to east from night to night. March and April provide good nights for seeing the Gegenschein as it then lies in an area of sky far from the Milky Way.
Even so, it is very subtle to the unaided eye. Look south at about 1 a.m. local daylight time.
However, this year, in early April the Gegenschein will be more difficult as it will then lie right on top of Jupiter, as that planet reaches its point opposite the Sun on April 7. Jupiter will then be superimposed on the Gegenschein.
The main image at top is a 7-image vertical panorama of the spring sky, from Corvus and Virgo above the horizon, up past Leo, into Ursa Major and the Big Dipper overhead. Spica lies below bright Jupiter, Arcturus in Böotes is at left, while Regulus in Leo is at right. The grouping of stars near centre is the Coma Berenices star cluster.
Earlier in the night, I shot the sky’s other main glow – the Milky Way, as the winter portion of the Milky Way around Orion set into the southwest.
But over in the west, at the right edge of the frame, is the Zodiacal Light, caused by the same dust particles that create the Gegenschein, but that are located in the inner solar system between us and the Sun.
We bid adieu to the winter Milky Way now. As it departs we are left with an evening sky without the Milky Way visible at all. As seen from northern latitudes it lies along the horizon.
But later in spring, late at night, we’ll see the summer Milky Way rising, beginning its seasons of prominence until late autumn.
In a winter of cloud, the skies cleared for a magical night in the Alberta Badlands.
Two weeks ago, on February 28, I took advantage of a rare and pristine night to head to one of my favourite spots in Dinosaur Provincial Park, to shoot nightscapes of the winter sky over the Badlands.
A spate of warm weather had melted most of the snow, so the landscape doesn’t look too wintery. But the stars definitely belong to winter in the Northern Hemisphere.
The main image above shows the winter Milky Way arching across the sky from southeast (at left) to northwest (at right). The tower of light in the west is the Zodiacal Light, caused by sunlight reflecting off dust particles in the inner solar system. It is an interplanetary, not atmospheric, effect.
This is a stitch of 6 segments with the 12mm Rokinon lens at f/2.8 for 30 seconds each, with the Nikon D750 at ISO 6400, mounted portrait. Stitched with PTGui.
Above, this 360° version of the scene records the entire sky, with the winter Milky Way from horizon to horizon. With a little averted imagination you can also trace the Zodiacal Light from west (right) over to the eastern sky (left), where it brightens in the diffuse glow of the Gegenschein, where dust opposite the Sun in the outer solar system reflects light back to us.
This is a stitch of 6 segments taken with the 12mm full-fame fish-eye Rokinon lens at f/2.8, all 30-second exposures with the Nikon D750 at ISO 6400. The camera was aimed portrait with the segments at 60° spacings. Stitched with PTGui using equirectangular projection with the zeith pulled down slightly.
A rectangular version of the panorama wraps the sky around from east (left), with Leo rising, to northeast (right), with the Big Dipper standing on its handle. I’ve added the labels in Photoshop of course.
This is a stack of 8 x 30-second exposures for the ground, mean combined to smooth noise, plus one 30-second exposure for the sky. All at f/2.2 with the Sigma 20mm Art lens and Nikon D750 at ISO 6400.
Here, in a single-frame shot, Orion is at centre, Canis Major (with Sirius) is below left, and Taurus (with Aldebaran) is at upper right. The Milky Way runs down to the south. The clusters M35, M41, M46 and M47 are visible as diffuse spots, as is the Orion Nebula, M42, below Orion’s Belt.
The late winter evening Zodiacal Light, from at Dinosaur Provincial Park, Alberta, February 28, 2017. This is a stack of 7 x 30-second exposures for the ground, mean combined for lower noise, plus one 30-second exposure for the sky, all at f/2 with the 20mm Sigma Art lens, and Nikon D750 at ISO 6400.
This is certainly my best shot of the evening Zodiacal Light from my area in Alberta. It is obvious at this time of year on moonless nights, but requires a site with little urban skyglow to the west.
It is best visible in the evening from northern latitudes in late winter and spring.
Here, Venus is just setting above the badlands landscape. The Andromeda Galaxy is at right, the Pleiades at left. The Milky Way runs across the frame at top.
There is a common belief among nightscape photographers that the Milky Way can be seen only in summer. Not so.
What they mean is that the brightest part of the Milky Way, the galactic centre, is best seen in summer. But the Milky Way can be seen in all seasons, with the exception of spring when it is largely absent from the early evening sky, but rises late at night.
With the harvest in full swing, the aurora and Moon lit the fields on a clear September evening.
This night, September 19, showed prospects for a good display of Northern Lights, and sure enough as it got dark a bright, well-defined arc of Lights danced to the north.
I headed off to some photogenic spots near home, on the prairies of southern Alberta. By the time I got in place, the aurora had already faded.
However, the arc still photographed well and provided a great backdrop to these rural scenes. The rising Moon, then 3 days past full, lit the foreground. In the lead image, lights from combines and trucks working the field behind the bins are at left.
A diffuse arc of aurora and the rising waning gibbous Moon light the sky over the old barn near home at harvest time, September 19, 2016. The glows from Strathmore and Calgary light the clouds to the west at far left. The Big Dipper shines over the barn, with Capella and the stars of Perseus at right. The Pleiades are rising to the left of the Moon. This is a panorama of 5 segments, with the 20mm lens and Nikon D750. Stitched with ACR.
The image above was from later in the night, just down the road at a favourite and photogenic grand old barn.
The Big Dipper and a diffuse aurora over the old barn near home, in southern Alberta, on September 16, 2016. The waning gibbous Moon off camera at right provides the illumination. This is a stack of 4 exposures, averaged, for the ground to smooth noise and one exposure for the sky to keep the stars untrailed. All 13 seconds at f/2.8 with the Sigma 20mm lens, and ISO 1600 with the Nikon D750. Diffraction spikes on stars added with Noel Carboni’s Astronomy Tools actions.
Note the Big Dipper above the barn. A waning and rising Moon like this is great for providing warm illumination.
The time around equinox is usually good for auroras, as the interplanetary and terrestrial magnetic fields line up better to let in the electrons from the Sun. So perhaps we’ll see more Lights, with the Moon now gradually departing the evening sky.
On the evening of January 20 for North America, the Full Moon passes through the umbral shadow of the Earth, creating a total eclipse of the Moon.
