Orion and Canis Major over Lake Annette, in Jasper National Park, with Sirius and other stars reflected in the waters. Orion appears over Whistler peak, illuminated in part by lights from the Jasper townsite. I shot this on the morning of October 25, 2015, as the sky was brightening with dawn twilight. The exposure was 25 seconds at f/2.8 with the 24mm lens and at ISO 3200 with the Canon 6D. The camera was untracked, on a fixed tripod. No filter was employed - the fuzzy star glows come from high haze in the sky that morning.
An aurora display appears to the right of Pyramid Mountain and over Pyramid Lake, in Jasper National Park, Alberta on Oct 24/25, 2015. This is one frame from a 600-frame time-lapse sequence. Exposure was 15 seconds at f/4 and ISO 800 in the bright moonlight, with the Nikon D750 and 24mm Sigma lens.
The Big Dipper over Pyramid Mountain at Pyramid Lake, Jasper National Park, Alberta, on Oct 24, 2015. Illumination is from a waxing gibbous Moon. This is a stack of 4 exposures, mean combined, for the ground to smooth noise with one of the exposures adding the sky, to prevent trailing. Each was 15 seconds at f/4 and ISO 800 with the Nikon D750 and Sigma 24mm lens.
