Stars setting in trails over the Athabasca Glacier and Columbia Icefields, Sept 14, 2014. The Milky Way is trailed at right. This is a stack of 100 exposures, composited with Advanced Stacker Plus actions in Photoshop, with the ground coming from a subset stack of 8 images to reduce noise. Each exposure, taken as part of a time-lapse sequence, was 45 seconds at f/2.8 with the 16-35mm lens at 23mm and Canon 6D at ISO 4000.
The stars setting into the west over the Columbia Icefields and Athasbasca (left) and Stutfield (right) glaciers, and Snowdome peak. I shot this Sept 6 under very clear skies and a bright waxing gibbous Moon off frame at left. I shot this from the moraine at the upper parking lot. This is a stack of 100 frames, each 20 seconds at f/2.8 with the 16-35mm lens at 22mm and Canon 5D MkII at ISO 1000. One frame was selected for the foreground, to ensure sharp shadows. Two other frames supply the point-like stars at the beginning and end of the trails. Stacked with Advanced Stacker Plus actions in Photoshop.
Star trails over Patricia Lake and Pyramid Mountain in Jasper National Park. Moonlight provides the illumination and a faint aurora is at lower right in the northeast. The Big Dipper is the main pattern right of centre. This is a stack of about 100 frames to create the star trails using Advanced Stacker Plus actions in Photoshop with the Long Comet streaks effect. Two additional single frames are layered in, one for the ground from one of the frames and another for the sky to create the point-like stars after a gap at the ends of the trails. This frame came from a minute or so after the last trail frame was taken. Each exposure was 20 seconds at ISO 1600 with the Canon 60Da and Rokinon 14mm lens at f/2.8. The frames had to be cropped to cut out car lights from a road off frame at right.
