A star trail sequence shot at Patricia Lake in Jasper National Park, Alberta, showing two cameras at work shooting a time-lapse dolly motion control sequence (at left) and a static camera star trail sequence (at right). This is a stack of 100 frames out of 400 shot by the third camera, with one frame shot a couple of minutes after the sequence and layered in to add the blurry but point-like stars at the ends of the trails, including the Big Dipper. Each frame was 32 seconds at f/4.5 (stopped down too much by accident) with the 24mm lens at Canon 6D at ISO 800 in bright moonlight from the waxing gibbous Moon.
A circumpolar star trail composite, shot at the old Larson Ranch site in the Frenchman Valley at Grasslands National Park, Saskatchewan, August 27/28, 2014. The pioneer cabin was the home of the legendary western author and movie star Will James, born Ernest Dufault in Quebec. He lived in this cabin when he worked the ranches in the area. The aurora was excellent this night. This is a stack of 20 1-minute exposures at ISO 2500 with the 15mm full-frame fish-eye lens at f/3.2 and the Canon 6D. The foreground and point-like stars are from the first frame in the series.
The Milky Way over the old corral at the site of the 76 Ranch in the Frenchman Valley in Grasslands National Park, Saskatchewan. I shot this Aug 26 on a perfect night, with aurora beginning to kick up but still low in brightness when I shot this so the sky was dark. The foreground is lit by starlight, by the aurora brightening in the north, and by the occasional flashes of spotlights from naturalists down the valley spotting for nocturnal ferrets. The green bands in the sky are from natural airglow. This is a composite stack of 5 images: 4 tracking the sky on the Sky-Watcher Star Adventurer for the sky and 1 untracked shot with the motor off, which supplied the sharp ground. The blurred ground in the tracked shots was masked out in Photoshop. All images were 3 minutes at f/2.5 with the 24mm lens and Canon 5D MkII at ISO 1600.
