I’m pleased to announce that my “Nightscapes and Time-Lapses” eBook is now available for all devices as a “universal” PDF!
First published in 2014, and revised several times since then, my How to Photograph and Process Nightscapes and Time-Lapses eBook had been available only for Apple devices through the Apple iBooks Store. Not any more!
Over the years, many people have inquired about an edition for other devices, notably Android and Windows tablets. The only format that I can be sure the wide array of other devices can read and display as I intend it is PDF.
To convert the interactive Apple iBook into a PDF required splitting the content into two volumes:
Volume 1 deals just with Photography in 425 pages.
Volume 2 deals just with Processing, also in 425 pages.
Volume 2 includes all the same step-by-step tutorials as the Apple edition, but spread over many more pages. That’s because the Apple Edition allows “stacking” many processing steps into a one-page interactive gallery.
In the PDF version, however, those same steps are shown over several pages. And there are about 50 processing tutorials, including for selected non-Adobe programs such as Affinity Photo, ON1 Photo RAW, and DxO PhotoLab.
The other main difference is that, unlike the Apple version, I cannot embed videos. So all the videos are provided by links to Vimeo feeds, many “private” so only my ebook owners have access to those videos.
Otherwise, the combined content of the two PDFs is the same as the Apple iBooks edition.
I’ve also updated the Apple iBooks version (to v3.1) to revise the content, and add a few new pages: on Luminosity Mask panel extensions, southern hemisphere Milky Way and Moon charts, and even the new Nikon Z6 camera. It is now 580 pages.
Owners of the previous Apple iBooks edition can get the updated version for free. In iBooks, check under Purchased>Updates.
Both Apple and PDF editions are now in sync and identical in content. I think you’ll find them the most comprehensive works on the subject in print and in digital.
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.
Mars and the Milky Way over the tipis at Two Trees area in Grasslands National Park, Saskatchewan on August 6, 2018. Some light cloud added the haze and glows to the planets and stars. 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. Observers enjoy their views of the sky at left while an astrophotographer attends to his camera control computer at right. 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.
A blend of images to show the stars of the southern sky moving from east to west (left to right) over the Rocky Mountains at Bow Lake, in Banff, Alberta. The main peak at centre is Bow Peak. Crowfoot Glacier is at far left; Bow Glacier is at right below the Milky Way. 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 Bow Lake this night on July 16, 2018, though they appear large and out of focus. This is a stack of 300 images for the star trails, stacked with the Ultrastreak 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 with the 15mm Laowa lens and Sony a7III at ISO 3200. All were taken as part of a time-lapse sequence. Bands of airglow add the green streaks to the sky.
The stars trailing as they move east to west (left to right), ending with the Milky Way and Galactic Centre (right) over Storm Mountain and the Vermilion Pass area of the Continental Divide in Banff National Park, Alberta. Mars is the bright trail at left. Saturn is amid the Milky Way at right. This was July 15, 2018. The lights at left are from the Castle Mountain interchange at Highways 1 and 93. 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.

Solstice nights have been filled with twilights, planets, and noctilucent clouds.
Astronomers tend to curse the short nights and late sunsets of summer solstice. But the bright nights do offer unique sights.
Over the last few nights I’ve set up at what I call “Solstice Pond,” a prairie slough near home ideal for shooting the aurora to the north and, at this time of year, the glow of twilight and noctilucent clouds.
Below is the view on the night before solstice, looking north toward the glow of “perpetual twilight” that lights the northern horizon at solstice time from my latitude of 50° north.
From farther north the twilight would be more prominent, while above the Arctic Circle at 66° N latitude, the twilight turns to full daylight as the Sun never sets.
The view looking south this night, with the Moon just off frame at right, includes the Milky Way at centre, with Saturn embedded, flanked by bright Jupiter at right and reddish Mars at left, both casting shimmering “glitter paths” on the still waters.
A few nights later (below), on June 24, the star of the solstice sky put in an appearance. Bright noctilucent clouds (NLCs) shone to the north, reflected in the pond.
These are water vapour clouds 80 kilometres high at the edge of the atmosphere – in the mesosphere – almost in space. They form over the Arctic in summer, and are high enough to remain sunlit even in the middle of the night as they catch the Sun shining over the pole.
Southern Western Canada – the Prairies where I live – is well-placed to see them, as we are far enough north to see them in our sky, but not so far north that our sky is too bright.
An even better display appeared two nights later, on June 26, brighter and with more structure.
The curving arc of the top of the display defines the most southerly edge where sunlight is able to reach. That edge drops lower through the first part of the night, as the Sun itself drops lower below the horizon. This causes less of the NLC display to be sunlit.
You can see this effect of the changing illumination of the clouds in this time-lapse compilation from June 26 (below).
Also notice the waving motion of the clouds. It is as if the NLC material is flowing over standing waves in the atmosphere – and it is! The waves are called “gravity waves,” and are bumps in the high atmosphere created by disturbances far below in the normal layers of the atmosphere, the stratosphere and troposphere.
The video includes two clips shot simultaneously: from a camera with a 24mm wide-angle lens, and from a camera with an 85mm moderate telephoto. Expand to view full screen in HD.
The motion, here over an hour or more, is hypnotic. The NLCs move right to left (east to west), while the dark normal weather clouds on the horizon are blowing left to right (west to east). The stars are also turning left to right. The water ripples in the wind, while ducks swim by.
A clear break between storms provided a marvellous night in the mountains to shoot nightscapes.
Every year I travel to Waterton Lakes National Park in southwest Alberta to deliver public talks and photo workshops, usually as part of one of the festivals held each year. I was there June 15 to 17 to participate in the annual Wildflower Festival.
On Sunday, June 17 skies cleared to allow my workshop group to travel to one of my favourite spots, Maskinonge, to practice nightscape shooting techniques. The sunset was stunning, then as skies darkened the Moon and Venus over Waterton River provided the scene.
As twilight deepened, a display of noctilucent clouds appeared to the north, my first sighting of the season for this unusual northern sky phenomenon. These clouds at the edge of space are lit by sunlight even at local midnight and form only around summer solstice over the Arctic.
As the sky slowly darkened and the Moon set, the Milky Way appeared arching across the east and down into the south. The sky was never “astronomically dark,” but even with perpetual twilight illuminating the sky, the Milky Way still made a superb subject, especially this night with it reflected in the calm waters on this unusually windless night for Waterton.
On the way back to town, I stopped at another favourite spot, Driftwood Beach on Middle Waterton Lake, to take more images of the Milky Way over Waterton, including the lead image at top.
It was a perfect night in Waterton for shooting the stars and enjoying the night sky. By morning it was raining again!
Here’s a short promo video, one that also opens the ebook as one of the embedded videos.
I originally published this ebook in 2014, then revised it in late 2016. Here’s what’s new in this 2018 Third Edition:
Updated equipment (cameras, lenses, filters, time-lapse gear) to reflect what’s current as of mid-2018. For example I added: the Revolve Camera slider; functions from the Canon 6D MkII; and information about the Sony a7III Mirrorless.
Updated the processing tutorials with current software: Photoshop CC2018, Lightroom Classic CC, Starry Landscape Stacker, TLDF, Timelapse Workflow, and LRTimelapse version 5.
Added tutorials on selected non-Adobe programs: DxO PhotoLab, ON1 Photo RAW, Affinity Photo, and the extensions Raya Pro 3 and Dr. Brown’s Services.
Added some 50 new topic pages, such as on memory cards and exposure blending.
In addition I’ve performed “housekeeping chores” such as:
Removing some embedded movies to reduce the file size and
Converting interactive diagrams into labeled images and
Flattening some of the interactive image galleries, all for facilitating conversion to PDFs for non-Apple platforms.
Improving the resolution of most tutorial screenshot images.
Improving many diagrams and updating many images.
Merging the chapter on Intervalometers into Chapter 1.
Plus I’ve added a section on lunar eclipses back in. Yay!
Here are screen shots of sample chapter content pages, to provide an idea of what the ebook contains and looks like.
All current owners of the older editions get the Third Edition update for free through the iBooks app (Mac or iPad, and also iPhone).
I hope you enjoy the new edition. Tell your friends! And do leave a rating or review at the iBooks sales page. Thanks!
And yes, for non-Apple people, a non-interactive PDF version for all other platforms (Windows and Android) is in production for later this year.
The strange aurora named Steve put on a show on Sunday, May 6.
The past weekend was a good one for Northern Lights here in Alberta and across western Canada.
A decent display lit the northern sky on Saturday, May 5, on a warm spring evening. I took in that show from a favorite spot along the Red Deer River.
The next night, Sunday, May 6, we were hoping for a better show, but the main aurora never amounted to much across the north.
Instead, we got a fine showing of Steve, an unusual isolated arc of light across the sky, that was widely observed across western Canada and the northern U.S. I caught his performance from my backyard.
Popularized by the Alberta Aurora Chasers Facebook group, Steve is the fanciful name applied to what still remains a partly unexplained phenomenon. It might not even be a true aurora (and it is NOT a “proton arc!”) from electrons streaming down, but a stream of hot gas flowing east to west and always well south of the main aurora.
Thus Steve is “backronymed” as Strong Thermal Emission Velocity Enhancement.
To the eye he appears as a grey arc, not doing much, but fading in, slowly shifting, then fading away after 30 to 60 minutes. He doesn’t stick around long.
The camera reveals his true colours.
This is Steve to the west, displaying his characteristic pink and white tints.
But overhead, in a fish-eye lens view, he displayed ever so briefly another of his talents – slowly moving fingers of green, called a picket fence aurora.
It was appropriate for Steve to appear on cue, as NASA scientists and local researchers who are working on Steve research were gathered in Calgary to discuss future aurora space missions. Some of the researchers had not yet seen Steve in person, but all got a good look Sunday night as they, too, chased Steve!
I shot a time-lapse and real-time videos of Steve, the latter using the new Sony a7III camera which can shoot 4K videos of night sky scenes very well.
The final video is here on Vimeo.

With summer approaching, the nights are getting shorter and brighter, but we here in western Canada can still see auroras, while aurora destinations farther north are too bright and lack any night skies.
Plus our latitude south of the main auroral oval makes western Canada Steve country!
