Aurora Reflections in Yellowknife


Auroral Arc over Tibbitt Lake

The Northern Lights are amazing from Yellowknife, in Canada’s Northwest Territories. 

A handful of locations in the world are meccas for aurora chasers. Yellowknife is one of them and, for me, surprisingly accessible with daily flights north.

In a two-hour flight from Calgary you can be at latitude 62° North and standing under the auroral oval with the lights dancing overhead every clear night.

Aurora Panorama at Tibbit Lake #2

The attraction of going in early September, as I did, is that the more persistent clouds of late autumn have not set in, and the many lakes and rivers are not yet frozen, making for superb photo opportunities.

Lakes down Highway 4, the Ingraham Trail, such as Prosperous, Prelude, and Pontoon are popular spots for the busloads of tourists who fly in every year from around the world.

On one magical night I and my local host and guide, Stephen Bedingfield, went to the end of the Trail, to where the Ice Road begins, to Tibbitt Lake, and had the site to ourselves. The aurora was jaw-dropping that night.

On other nights with less certain prospects I stayed in town, and still got a fine show on several nights, the Lights so bright they show up well even from within urban Yellowknife.

On another night we chased into clear skies down Highway 3 to the west, to a rocky plateau on the Canadian Precambrian Shield. Even amid the clouds, the aurora was impressive.

But it was the night at Tibbitt that was the highlight.

Here is the finale music video from movies shot that night, September 8, 2018, with two cameras: the Sony a7III used to take “real-time” 4K videos of the aurora motion, and the Nikon D750 used to take time-lapses.

The movie is in 4K. The music, Eternal Hope, is by Steven Gutheinz and is used by permission of West One Music.

“Nightscapes & Time-Lapses” Goes Universal!


How to Photograph and Process Nightscapes and Time-Lapses

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.

Cover-Volume1

Volume 2 deals just with Processing, also in 425 pages.

Cover-Volume2

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.

Cover-Apple 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.

To learn more and to buy, see my webpage at my AmazingSky site. 

Thanks!

Milky Way Over the Icefields

The Living Skies of Saskatchewan


Gazing at the Milky Way in Grasslands National Park

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.

Milky Way Panorama at 76 Ranch Corral

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.

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.

Twilight Panorama at SSSP 2018

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.

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.

Panorama of the Milky Way over the Great Sandhills

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!

Four Planets Along the Ecliptic at Great Sandhills

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.

Sunset at Great Sandhills

If you are looking for a stellar experience under their “living skies,” I recommend Saskatchewan.

Banff by Night


Milky Way Reflections at Bow Lake

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.

Conjunction over the Continental Divide with Train

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.

The Milky Way and Mars over Storm Mountain

This was the view later with the Milky Way and Mars over Bow Valley and Storm Mountain.

Bow Lake by Night Panorama

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.

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.

Mars and the Milky Way at Herbert Lake

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.

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.

Honoured with a Stamp


4557_CP_Astronomy Stamp_Booklet-2-FA_V2

One of my aurora images now appears on a new stamp issued by Canada Post to mark the 150th Anniversary of the Royal Astronomical Society of Canada. 

It is always a treat to see one of your images in print, but this is a rare privilege indeed. On June 29 Canada Post unveiled a new set of astronomy stamps, one of which features an aurora image from me, shot March 14, 2016 from the Churchill Northern Studies Centre, in Churchill, Manitoba. I shot it from the second floor observing deck, looking east to the rising sky.

The other stamp features a Milky Way image shot by fellow RASC member Matt Quinn taken from the Bruce Peninsula, Ontario.

If you view the stamps under UV “black light” more image information is revealed!

The stamps were issued to mark the 150th Anniversary of the Royal Astronomical Society of Canada, which began as an exclusive “gentlemen’s club” in Toronto in 1868. It is much more inclusive today, as it should be, with a membership of 5500 people from across Canada.

IMG_3581

The stamps were unveiled at a ceremony at the RASC’s annual General Assembly, this year held in Calgary where I live. Representatives from Canada Post, and of course the RASC executive were in attendance.

IMG_6276

This shows (L to R): me, David Foote (author, eclipse chaser, and member of the Stamp Advisory Committee), Chris Gainor (incoming RASC President), and Colin Haig (outgoing RASC President) at the unveiling. Matt Quinn was not able to attend. All those present (including members of the local Philatelic Society) received first day covers which David and I autographed.

IMG_E6274

This was certainly a great honour, a once-a-lifetime event I’m sure. I am grateful to the RASC officials such as Randy Attwood who lobbied for the stamp issue, a process that began three years ago.

I was first contacted by Canada Post in October 2016 though the final image was not selected until October 2017. Since then, its use was to be kept secret until the “Big Reveal” unveiling at the General Assembly. For the most part, it was!

IMG_E6264

This is a shot I took of some of my fellow RASC members and friends from across Canada enjoying me taking a picture of them at the ceremony at the University of Calgary.

Many thanks! And now mail some letters!

On Solstice Pond


Selfie at Solstice Pond

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.

Solstice Twilight Panorama over Prairie Pond
A 120° panorama of the summer solstice twilight (at 12:30 am local time) looking north over the prairie pond near home in southern Alberta, taken June 19/20, 2018. Some very faint noctilucent clouds are at left but fading, while some very faint rays of auroral curtains are also visible in the photo but were invisible to the eye. The bright star Capella is at centre and reflected in the calm waters. Perseus is at right of centre. The red lights at right are from the wind turbines at the Wintering Hills Wind Farm. This is a stitch of 6 segments, with the 35mm lens at f/2.5 for 20 seconds each with the Canon 6DMkII at ISO 400.

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.

Planet Panorama at a Prairie Pond
A 160° panorama looking south near summer solstice time in June 2018, with the bright planets Mars (left) and Jupiter (right) and their glitter paths on the water flanking the Milky Way and Saturn in Sagittarius above the pinkish Lagoon Nebula. The waxing Moon is setting off frame at right brightening the sky and lighting the landscape. The sky is also blue from the solstice twilight. The stars of Scorpius shine between Jupiter and the Milky Way. Some faint bands of red and green airglow are visible at left, despite the bright sky. This is a stitch of 8 segments, all for 25 seconds with the 35mm lens at f/2.2 and Canon 6D MkII at ISO 800.

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.

Noctilucent Clouds over Prairie Pond (June 24, 2018)
A fine display of noctilucent clouds (NLCs) or polar mesospheric clouds, reflected in a local prairie pond near home in southern Alberta. The display started with wisps much higher in the north but they faded as the Sun dropped lower, with the display at this extent by the time I reached my spot and took this panorama. Leo and Regulus are setting at far left in the west, as is Venus just above the horizon at left. Capella and Auriga are at centre, and circumpolar, while the stars of Perseus at right, rising. This is a panorama of 9 segments, at 15° spacings, with the 35mm lens at f/2.8 for 13 second exposures with the Canon 6D MkII at ISO 400. Stitched with Adobe Camera Raw.

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.

Panorama of Noctilucent Clouds (June 26, 2018)
A panorama of a fine display of noctilucent clouds across the northern horizon over an angle of about 60°. This was on June 26, 2018 at about 11:45 pm. Capella is just left of centre. The display faded as the solar illumination dropped and the clouds darkened from the top down. This was from the small pond near home in southern Alberta. This is a stitch of 7 segments, each 2 seconds at f/2.8 with the 85mm Rokinon lens and Canon 6D MkII at ISO 400. Stitched with ACR.

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.

It was a magical night at Solstice Pond.
