The Big Dipper and Arcturus (at left) over the peaks of Waterton Lakes National Park, Aug 30, 2013. Taken with the 24mm lens at f/2.5 and Canon 5D MkII at ISO 3200 for 30 seconds. A faint aurora adds colour at right, and airglow adds the greenish tint to the sky.
A panorama of the night sky and Milky Way, from Waterton Lakes National Park, on the Red Rock Canyon Road. The light at left is from the Prince of Wales Hotel and the glow from the townsite. The Big Dipper is at far right. The green at left is from airglow, while the yellow and magenta at right is from light pollution from Pincher Creek and Crowsnest Pass, and perhaps low-level aurora. This is a 7-section pan with the 24mm lens and Canon 5D MkII each for 30 seconds at f/2.2 and ISO 1600. Stitched in Photoshop.
An Iridium satellite flare over Castle Mountain, Banff, Aug 24, 2013, above the Big Dipper. The scene is lit by light from the waning gibbous Moon. Part of a 150-frame time-lapse sequece.
