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.

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.

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.

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!
The clouds cleared to present a magical night under the Moon in the Badlands of southern Alberta.
At last, a break in the incessant clouds of November, to provide me with a fine night of photography at one of my favourite places, Dinosaur Provincial Park, declared a U.N. World Heritage Site for its deposits of late Cretaceous fossils.
I go there to shoot the night sky over the iconic hoodoos and bentonite clay hills.
November is a great time to capture the equally iconic constellation of Orion rising in the east in the early evening. The scene is even better if there’s a Moon to light the landscape.
November 27 presented the ideal combination of circumstances: clear skies (at least later at night), and a first quarter Moon to provide enough light without washing out the sky too much and positioned to the south and west away from the target of interest – Orion and the winter sky rising in the east.
Below is a slide show of some of the still images I shot, all with the Canon 6D MkII camera and fine Rokinon 14mm f/2.5 lens, used wide open. Most are 15-second exposures, untracked.
I kept another camera, the Nikon D750 and Sigma 24mm Art lens, busy all night shooting 1200 frames for a time-lapse of Orion rising, with clouds drifting through, then clearing.
Below is the resulting video, presented in two versions: first with the original but processed frames assembled into a movie, followed by a version where the movie frames show accumulating star trails to provide a better sense of sky motion.
To create the frames for this version I used the Photoshop actions Advanced Stacker Plus, from StarCircleAcademy. They can stack images then export a new set of frames each with the tapering trails, which you then assemble into a movie. I also used it to produce the lead image at top.
The techniques and steps are all outlined in my eBook, highlighted at top right.
The HD movie is just embedded here, and is not published on Vimeo or YouTube. Expand to fill your screen.
To help plan the shoot I used the astronomy software Starry Night, and the photo planning software The Photographer’s Ephemeris, or TPE. With it, you can place yourself at the exact spot to see how the Sun, Moon and stars will appear in sightlines to the horizon.
Here’s the example screen shot. The spheres across the sky represent the Milky Way.
Look east to see Orion now in the evening sky. Later this winter, Orion will be due south at nightfall.
It was a perfect night at a dark site in southern Alberta. The Milky Way shone to the south and aurora danced to the north.
I had scouted out this location in June and marked it on my calendar to return in the fall when the centre of the Milky Way would be well-placed to the southwest.
The site is Police Outpost Provincial Park, named for the North West Mounted Police fort that once occupied the site, guarding Canada’s sovereignty in the late 1800s.
One result from the night of shooting is the opening image, the first frame from a time-lapse taken while deep blue twilight still coloured the sky. The main peak is Chief Mountain in Montana.
To the north an aurora display kicked up over the lake. While it never got very bright, it still provided a photogenic show over the still waters.
The waters were calm on this windless night (rare for southern Alberta), and so reflected the stars and Northern Lights beautifully.
Here, the Big Dipper reflects in the lake as we look north to the Lights. The movie below compiles still images and two time-lapse sequences, of the Lights and Milky Way. The sounds are the natural sounds I recorded on site, as flocks of geese were getting ready to migrate and the owls hooted.
