Stars in the northwestern sky trailing as they set behind the mountain of the continental divide in Banff, behind Lower Waterfowl Lake and Mt. Cephren. The frames for this composite stack were shot as part of time-lapse sequence on August 11, 2014 using a Rokinon 14mm lens and Canon 5D MkII camera. Each frame was 15 seconds at f/2.8 and ISO 3200. Moonlight provide the illumination, from a Moon a day past full. Images were stacked with Advanced Stacker Plus actions out of Photoshop using Long Streaks effect. The foreground is from one frame.
