On November 11, I traveled to the near-flung corners of my backyard to observe the rare transit of Mercury across the Sun.
History is replete with tales of astronomers traveling to the far corners of the Earth to watch dark objects pass in front of the Sun — the Moon in eclipses, and Mercury and Venus in transits.
On November 11, to take in the last transit of Mercury until 2032, I had planned a trip to a location more likely to have clear skies in November than at home. A 3-day drive to southern Arizona was the plan.
But to attend to work and priorities at home I cancelled my plans. Instead, I decided to stay home and take my chances with the Alberta weather, perhaps making a run for it a day’s drive away if needed to chase into clear skies.
As it turned out, none of that was necessary. The forecast for clear, if cold, skies held true and we could not have had a finer day for the transit. Even the -20° C temperatures were no problem, with no wind, and of course sunshine!
Plus being only steps from home and a warming coffee helped!
As it turned out, the site in Arizona I had booked to stay was clouded out for the entire event. So I was happy with my decision!
For my site in Alberta, as for all of western North America, the Sun rose with the transit in progress. But as soon as the Sun cleared the horizon there was Mercury, as a small, if fuzzy, black dot on the Sun.
As the Sun rose the view became sharper, and was remarkable indeed — of a jet black dot of a tiny planet silhouetted on the Sun.
I shot through two telescopes, my 4-inch and 5-inch refractors, both equipped with solar filters of course. I viewed through two other telescopes, for white-light and hydrogen-alpha filtered views.
I was able to follow the transit for three hours, for a little more than half the transit, until Mercury exited the Sun just after 11 a.m. MST. The view below is from moments before Mercury’s exit, or “egress.”
I shot still frames every 15 seconds with each of the two cameras and telescopes, for a time-lapse, plus I shot real-time videos.
At this transit Mercury passed closer to the centre of the Sun’s disk than it will for any other transit in the 21st century, making this event all the more remarkable. That point is recorded above, from a shot taken at 8:19 a.m. MST.
Stacking a selection of the time-lapse frames, ones taken 1-minute intervals, produced this composite of the transit, from just before mid-transit until Mercury’s egress.
I assembled all the best images and 4K videos together into a movie, which I narrated live at the telescope as the transit was happening. I hope this provides a sense of what it was like to view this rare event.

We won’t see another until 2032, but not from North America. The next transit of Mercury viewable from here at home is not until 2049! This was likely my last transit, certainly for a while!
It was a fabulous week of clear skies and dancing auroras in and around Yellowknife in Canada’s North.
For the second year in a row I traveled due north from home in Alberta to visit Yellowknife, capitol of Canada’s Northwest Territories. At a latitude of 62° North, Yellowknife lies directly under the auroral oval and so enjoys views of the Northern Lights on almost every clear night.
During my 8-night stay from September 3 to 10 almost every night was clear and filled with auroras.
Somba K’e Park
The Lights can be seen even from within the downtown core, as the opening image shows, taken from the urban Sombe K’e Park looking over Frame Lake and the Prince of Wales Museum.
The Museum is lit with rippling bands of coloured light that emulate the aurora borealis.
A favourite urban site for viewing the Lights is the Pilot’s Monument lookout in the middle of Yellowknife’s Oldtown district. This panorama sweeps from northeast at left to west at far right, looking mostly south over the downtown core.
This night even the urban lights were not enough to wash out the Lights as they brightened during a brief substorm.
Another good urban site that gets you away from immediate lights is the open spaces of Rotary Park overlooking the houseboats anchored in Yellowknife Bay. This panorama again sweeps from east to west, looking toward to the waxing Moon low in the south.
Again, despite the urban lights and moonlight, the Lights were spectacular.
The main viewing sites for the Northern Lights are down Highway 4, the Ingraham Trail east of the city away from urban lights.. One of the closest stops is a parking lot on the shore of a backwater bay of Prosperous Lake. It’s where many tourist buses stop and unload their passengers, mostly to get their selfies under the Lights.
But with patience you can get your own photos unencumbered by other lights and people, as I show below.
On one of my nights I stopped at Prosperous on the way to sites farther down Ingraham Trail to catch the twilight colours in the stunningly clear sky.
This small lake and picnic site farther along the Trail serves as a great place to shoot the Lights reflected in the calm waters and looking north. I spent one of my nights at Madeline Lake, a popular spot for local residents to have a campfire under the Lights.
And it’s popular for tour buses, whose headlights shine out across the lake as they arrive through the night, in this case casting my long shadow across the misty lake.
However, again with patience it is possible to get clean images of the aurora and its reflections in the lake.

The Big Dipper is at left; Capella at far right. This is a single 8-second exposure with the 15mm Laowa lens at f/2 and Sony a7III at ISO 1600.
Farther down the Trail is a spot the tour buses will not go to as a visit to the Ramparts waterfall on the Cameron River requires a hike down a wooded trail, in the dark with bears about. Luckily, my astrophoto colleague, amateur astronomer, and local resident Stephen Bedingfield joined me for a superb shoot with us the only ones present at this stunning location.
The view looking the other way north over the river was equally wonderful. What a place for viewing the Northern Lights!
The view from a viewpoint early on the trail down to the Ramparts and overlooking the Cameron River yielded a superb scene with the low Moon and twilight providing the illumination as the Lights kicked up early in the evening.
A favourite spot is the major camping and boat launch area of Prelude Lake Territorial Park. But to avoid the crowds down by the shoreline, Stephen and I hiked up to the overlook above the lake looking north. A few other ardent photographers joined us. This was another spectacular and perfect night.
September is a superb time to visit as the lakes are still open and the autumn colours make for a good contrast with the sky colours.
The panorama below takes in the Big Dipper at left, Capella at centre, and with the Pleiades and Hyades rising at right of centre.
I used the 8mm fish-eye lens to capture the entire sky, the only way you can really take in the whole scene on camera. When the Lights fill the sky you don’t know which way to look or aim your camera!

There are many other scenic spots along the Trail, such as Pontoon Lake, Reid Lake, and Tibbitt Lake at the very end of Ingraham Trail. For images and movies I shot last year at Tibbitt Lake, see my blog post at Aurora Reflections in Yellowknife.
But in my 8 nights in Yellowknife this year I managed to hit many of the key aurora spots for photography and viewing. I recommend a visit, especially in September before autumn clouds roll in later in the season, and while the lakes are not frozen and nighttime temperatures are mild.
Here’s a 3-minute music video of clips I shot from all these sites showing the motion of the Lights as it appeared to the eye in “real-time,” not sped up or in time-lapse.

As I do a couple of times a year, earlier this month I was cruising the coast of Norway chasing the Northern Lights – successfully!
One of my “retirement gigs” is to serve as a lecturer for the educational travel company Road Scholar (formerly Elderhostel) on some of their aurora cruises along the Norwegian coast on one of the Hurtigruten ferry ships.
This time, as I was last autumn, I was on Hurtigruten’s flagship coastal ferry, the m/s Trollfjord.
Our tour group was treated to five fine nights with auroras, an unusually good take out of the 12-day round trip cruise from Bergen to Kirkenes and back to Bergen. Our first look, above, was on February 27, but through cloud.
But after we reached the top end at Kirkenes and turned around for the southbound voyage, skies cleared remarkably. We had a wonderful four clear days and nights in a row, all with Northern Lights.
The best show was March 1, and when we were in port in the northern coastal village of Båtsfjord. The Lights danced overhead in the best show I had seen from Norway.
The next night we got a good show while we were in the port of Skjervøy.
As we continued south we emerged out from under the auroral oval zone, placing the Lights to the north, back in the direction we had come from.

Equally spectacular in my mind were some of the sunsets and twilight skies we enjoyed as we sailed through the Lofoten Islands, including on our visit to the narrow Trollfjord fjord for which the ship is named.
On our aurora nights I mostly shot “real-time” video of the Lights, using the low-light capability and 4K functions of the Sony a7III camera. The result is a music video linked to below.

For 11 non-stop nights in February we had clear skies and Northern Lights in Churchill.
Every year in winter I visit Churchill, Manitoba to attend to groups of aurora tourists at the Churchill Northern Studies Centre. Few groups (indeed only two over the 35 years the program has been offered) go away having not seen the Lights during the 5-night program.
But this year was the opposite exception. Even locals were impressed by the run of clear nights and displays in early February. It was non-stop Northern Lights!
Having auroras in Churchill isn’t unusual. It is located right under the auroral oval, so if it’s clear it would be unusual not to have some level of auroral activity.
But particles from a coronal hole at the Sun fired up the lights and gave us good shows every night, often starting early in evening, rather than at midnight as is typically the case. The shows pre-empted my evening lectures!
With shows every night, people soon got pretty fussy about what they’d get excited about. Some nights people viewed displays just from their bedroom windows!
Displays that on night one they would be thrilled with, by night four they were going back to bed awaiting a call later when “it gets really good!”
While auroras were active every night, the Lights showed little in the way of varied colours. Notably absent was any of the deep red from high altitude oxygen. The aurora particles were just not energetic enough I presume, a characteristic of solar minimum displays.
Increasingly, as we enter into the depths of solar minimum, with a prolonged lull expected for the next few years, aurora chasers will have to travel north to the Arctic and to the auroral oval to see displays on demand. The Lights won’t come to us!
We did see fringes of pink at times along the bottom of the auroral curtains from glowing nitrogen molecules, but even this was subtle to the eye, though obvious to the camera.
The nitrogen pinks are usually accompanied by rapid dancing motions that are amazing to watch.
The music video linked to below provides the best view of what we saw. It is made entirely of real-time video, not time-lapses, of the Lights as seen over several nights from the Studies Centre.
The video is in 4K, so do click through for the best viewing. And the Vimeo page provides more details about the video and the techniques.
We’ve embarked upon a new project to produce a comprehensive tutorial on deep-sky imaging with DSLR cameras.
This past week we launched a new KickStarter campaign to fund the production of a new multi-hour video course on how to capture deep-sky objects using entry-level telescope gear and DSLR cameras.
The emphasis in the course will be on techniques for taking and processing publication-quality images as simply and easily as possible.
The final video course will consist of several programs, including a video of one of our annual “Deep-Sky with Your DSLR” workshops presented locally here in Alberta. We’ve often had requests for a video version of those workshops, for those who cannot attend in person.
This is it! Here’s a short preview of some of the content.
We include the Workshop video, but we supplement it with much more: with video segments shot in the field by day and by night, showing how to setup and use gear, and shot in the studio showing how to process images.
While much of the content has been shot and edited, there’s more to do yet. Thus our KickStarter campaign to complete the funding and production. Backers of the project through KickStarter will get the final videos at a substantial discount off the final retail price.
All the details are on the project’s KickStarter page. Click through for the listing of course content, and options for funding levels. An FAQ page answers many of the common questions.
A week into the campaign and we’re just over 50% funded, but we have a way to go yet!
We hope you’ll consider backing our project, which we think will be unique on the market.
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.
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 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.
Steve Aurora – May 6, 2018 (4K) from Alan Dyer on Vimeo.
It is in 4K, if you choose to stream it at full resolution.
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!
I’m pleased to announce that after a year in production, our video tutorial series, Nightscapes and Time-Lapses: From Field to Photoshop, is now available.
It’s been quite a project! Over the last few years I’ve presented annual astrophoto workshops in conjunction with our local telescope dealer All-Star Telescope to great success.
However, we always had requests for the workshops on video. Attempts to video the actual workshops never produced satisfactory results. So we spent a year shooting in the field and in the studio to produce a “purpose-built” series of programs.
They are available now as a set of three programs, totalling 4 hours of instruction, for purchase and download at Vimeo at
For those wanting “hard copies” we will also be selling the programs on mailed USB sticks. See All-Star Telescope for info and prices. The downloaded version can also be ordered from there.
This series deals with the basics of capturing, then processing nightscape still images and time-lapse movies of the night sky and landscapes lit by moonlight and starlight.
Here’s the content outline:

Our video tutorial project is now live on Kickstarter!
For the last two years I’ve been involved in a project to produce a set of comprehensive video tutorials on how to shoot and process Nightscapes and Time-Lapses, to complement my ebook by the same name.
If you’ve not been able to attend my workshops – or even if you have! – these videos will provide you with all the information, and more, in a format you can review over and over.
We’ve shot all the field and studio footage, but to complete the production, we need your help. Back us on Kickstarterand we’ll be able to make the programs available this September, as downloads and on a shipped USB drive.
Our Kickstarter page has all the details. Early backers can purchase the tutorial programs now for as little as $55 – and that’s Canadian! – vs. $80 for the final retail price. The final programs will provide several hours of instruction, both in the field and at the computer.
If you have not participated in a Kickstarter campaign before, it is no risk. Nothing is charged to your credit card until and when the project is successfully funded after the 30-day campaign. If it isn’t successful, you are charged nothing.
Here’s our promo video describing the programs.
We have 30 days to make our goal. We invite you to join us in making our project a reality.
My latest music video includes images, time-lapses and real-time videos of the Northern Lights shot in February and March 2016 in Churchill.
While I’ve posted my recent images of the aurora here and at many social media sites, all the videos I shoot take more work before they are ready to unveil to the public. Videos work best when set to music.
In this case, I’m very pleased to have received permission from EverSound Music to incorporate the music of one of my favourite artists, John Adorney, in my latest music video montage. The selection is If a Rose Could Speak, from his 2013 album The Wonder Well. It features vocals by Daya.
The video incorporates still images, as well as time-lapse sequences, and real-time videos of the Northern Lights.
The all-sky time-lapses are intended to be projected in digital planetarium theatres, recreating the scene on their 360° domes.

ABOUT THE VIDEO
I shot all scenes at the Churchill Northern Studies Centre, near Churchill, Manitoba, on the shore of Hudson Bay at a latitude of 58° North. Churchill’s location places it under the usual location of the auroral oval, providing spectacular displays of Northern Lights even on nights when locations to the south are seeing nothing.
I was at the CNSC to present sets of 5-night aurora viewing programs to guests from across North America. Click the link above for more details on their programs. The 2016 aurora season is over, but we’ll have more aurora programs in January and February of next year.
I shot all images with Canon 6D and Nikon D750 DSLR cameras, usually at ISO 3200. The fish-eye all-sky sequences were with a Sigma 8mm lens on the Canon, while most of the still images and other full-frame time-lapses were with the Sigma 20mm Art lens on the Nikon. For the “rapid-cadence” time-lapses I used 1- to 2-second exposures at an interval of one second.
The real-time video clips were with the Nikon – set to ISO 25600 – and the Sigma wide open at f/1.4. While these clips are prone to digital noise, they do record the fast movement and subtle colour of the aurora much as the eye saw it. See my earlier music video with real-time clips shot February 12 for more examples of these.
The all-sky sequences were processed through LRTimelapse v4 software, to handle the huge range in brightness of the Lights. Real-time video clips were processed in Photoshop with the Camera Raw filter.
Temperatures ranged from a bitter -35° C to just (!) -15° C on most nights.
I kept the long-duration, all-sky, time-lapse camera going by placing it in a Camera Parka (www.atfrostedlens.com) and inserting disposable hand warmer packs inside the insulated parka. It worked very well, making it possible to shoot for up to 3 hours. Without it, the battery died after an hour.
My 10-minute video captures the Northern Lights in real-time video – no time-lapses here!
I hadn’t tried this before but the display of February 12, 2016 from Churchill, Manitoba was so active it was worth trying to shoot it with actual video, not time-lapse still frames.
I used very high ISO speeds resulting in very noisy frames. But I think the motion and colours of the curtains as they ripple and swirl more than overpower the technical limitations. And there’s live commentary!
Select HD and Enter Full Screen for the best quality.
Scenes have been edited for length, and I did not use all the scenes I shot in the final edit. So the scenes you see in the 10-minute video actually took place over about 20 minutes. But each scene is real-time. They show the incredibly rapid motion and fine structure in the auroral curtains, detail blurred in long multi-second exposures.
I used a Nikon D750 camera at ISO speeds from 12,800 to 51,200. While it is certainly very capable of shooting low-light video, the D750 is not optimized for it. A Sony a7s, with its larger pixels and lower noise, would have been a better camera. Next time!
The lens, however, was key. I used the new Sigma 20mm Art lens which, at f/1.4, is the fastest lens in its focal length class. And optical quality, even wide open, is superb.
The temperature was about -30 degrees C, with a windchill factor of about -45 C. It was cold! But no one in the aurora tour group of 22 people I was instructing was complaining. Everyone was outside, bundled up, and enjoying the show.
It was what they had traveled north to see, to fulfill a life-long desire to stand under the Northern Lights. Everyone could well and truly check seeing the aurora off their personal bucket lists this night.

The New Year’s sky was filled with Northern Lights, a panorama of stars, and a comet at dawn.
It was a busy night for stargazing as 2015 turned to 2016. A fine display of Northern Lights kicked off the celebrations, as curtains danced in the east as Orion rose (below).
Toward midnight the Lights kicked up again, now with Jupiter (on the horizon) and Leo rising in the east (below).
I shot hundreds of frames for time-lapse sequences, and assembled them into a short music video. Click on the buttons to enlarge it to HD.
Just before midnight, while the second time-lapse was going and the aurora was still active, but before the Last Quarter Moon rose to light the sky, I shot a set of tracked images taking in the entire winter sky from horizon to well past the zenith.
That image is at top. It takes in the winter sky and northern winter Milky Way, from Canis Major just above the horizon, up past Orion, then on up to Perseus and Cassiopeia at top right.
It shows how Orion and Sirius, the night sky’s brightest star, stand nearly due south at midnight on New Year’s Eve.
The final show of the night, now before dawn on New Year’s Day 2016, was Comet Catalina sitting right next to the bright spring star Arcturus. The comet was visible in the moonlight as a fuzzy object next to brilliant Arcturus, but the photo begins to show its faint tails, just standing out in the moonlit sky.
The comet will become more visible later this month once the waning Moon exits the dawn sky, as Catalina is expected to remain a nice binocular comet for most of the month as it heads high into northern sky.
