The Milky Way over the Milk River


The summer Milky Way with a meteor streaking at centre as a bonus. An aurora to the north off frame is lighting the foreground with a green glow. Haze and forest fire smoke obscure the horizon. I shot this at the Battle Scene viewpoint at Writing-on-Stone Provincial Park, in southern Alberta. Sagittarius and the galactic centre is on the horizon at left of centre. Capricornus is amid the haze at left of centre. On the horizon are the Sweetgrass Hills in Montana. The Milk River winds below amid the sandstone formations that are home to historic First Nations petroglyphs.  This is a single 30-second exposure with the Nikon D750 at ISO 3200 and Sigma 24mm Art lens at f/2, taken as part of a time-lapse sequence.

The summer Milky Way shines over the Milk River and the sandstone formations of Writing-on-Stone Provincial Park.

Earlier this week I spent two nights shooting at a favourite site in southern Alberta, near the U.S. border. Here, the Milk River winds through a small canyon and coulees lined with eroded sandstone formations called hoodoos. Carved on those hoodoos are ancient graffiti – petroglyphs dating back hundreds of years recording life on the plains. Thus the name: Writing-on-Stone.

It’s a beautiful place, especially so at night. I was there to shoot video scenes for an upcoming “How to Photograph the Milky Way” tutorial. And to collect images for the tutorial.

Above is a shot that is one frame from a time-lapse sequence, one that captures a meteor and the Milky Way over the Milk River, with the Sweetgrass Hills of Montana in the distance.

The summer Milky Way over the Milk River Valley and sandstone formations of Writing-on-Stone Provincial park, in southern Alberta. On the horizon are the volcanic Sweetgrass Hills in Montana. The red tint at top is from an aurora active that night and the ground is partly illuminated by green auroral light from the north. The Summer Triangle stars are at top left. Sagittarius is on the horizon sinking into the low clouds at botton right which are illuminated by lights from Sweetgrass, Montana. Clouds and smoke from forest fires to the west cut down the transparency and clarity of the sky this night, especially toward the horizon.  This is a stack of 4 x 3-minute tracked exposures for the sky, and 4 x 5-minute untracked exposures for the ground, all with the 15mm Canon full-frame fish-eye and Canon 6D at ISO 1000, on the iOptron Sky-Tracker unit.

This image is from a set of exposures I took with the camera and ultra-wide 15mm lens tracking the turning sky, to prevent the stars from trailing in long exposures. A set of images with the tracker motor turned off supplied the sharp ground.

It shows the sweep of the summer Milky Way, with some clouds and forest fire smoke intruding to the south.

In both images the ground is green because, in part, it is being lit by an aurora display going on behind the camera to the north.

An aurora display to the northeast over the Milk River Valley and Writing-on-Stone Provincial Park in southern Alberta, night of July 22/23, 2015. The ground is lit by aurora light. The view is looking east to the rising autumn constellations of Cassiopeia and Perseus at left, and Andromeda and Pegasus at centre. The Milky Way runs from left to top centre. I shot this with the 15mm full-frame fisheye and Canon 6D. The sky is from one image, but the ground is from a stack of 4 images, mean combined, to smooth noise.

Here’s the view looking east, with a green aurora fringed with red lighting the northern sky.

The arc of the auroral oval as seen from southern Alberta, July 22/23, 2015, from Writing on Stone Provincial Park, looking north over the flat prairie. The Big Dipper is at left. This is a 4-segment panorama with the Canon 60Da and 16-35mm lens at 16mm, stitched in Photoshop.

The display on the night of July 22/23 formed a classic arc across the north. This was my panoramic view of the vast auroral oval that was wrapping around the planet at far northern latitudes. Here, I was at 49° north, almost on the Canada-U.S. border, and well south of the main oval.

In all, it was a magical two nights at a scenic and sacred site.

The Milky Way over Milk River


Milky Way over Writing-on-Stone Park #2 (Sept 1, 2013)

The summer Milky Way sets over the Milk River on the last weekend of the summer.

This was the view last night, Sunday, September 1, from the Visitor Centre hill overlooking the spectacular Milk River valley and the sandstone formations of Writing-on-Stone Provincial Park, Alberta.

The Milk River winds around the park’s campsite, filled on a beautiful long weekend with campers enjoying the clear skies and temperatures in the 30s by day. At night, conditions were perfect. Warm, dry, no bugs, no wind. The best.

I set up two cameras: one for a day-to-night time lapse and one for a time-lapse panning the scene as the Milky Way moved to the west. These two images are frames from the latter.

Above is a shot from later in the evening when the sky was dark …

Milky Way over Writing-on-Stone Park (Sept 1, 2013)

… while this image is from earlier in the shoot, when the last of the blue twilight still lit the sky and the camera was aimed a little more to the east.

On the horizon at left in the image above lie the Sweetgrass Hills of Montana, a prominent landmark in southern Alberta. The yellow sky glows are from towns in northern Montana.

Lights from the campground and car headlights illuminate the landscape and the eroded hoodoo formations.

Writing-on-Stone Park preserves ancient rock petroglyphs that record scenes from before and after contact with Europeans. It is a sacred site to First Nations people and is a marvellous place for stargazing.
