Orion and the winter stars rising behind the old Pioneer Grain Co elevators at Mossleigh, Alberta, on December 28, 2016, in a two-panel panorama. A “vintage filter” from the Luminar plug-in was applied to the ground to add more of a sepia tone, though the ground was lit by yellow sodium vapour yard lights. Taken with 24mm lens and Nikon D750 for 13 seconds each, at f/2.8 and ISO 1000. Star diffraction spikes added with Astronomy Tools action.
The Northern Lights over the Athabasca River in Jasper National Park, Alberta, Canada, on October 22/23 at about 1:30 am. I shot this from an access point to the Athabasca River by the bridge on Highway 93 on the Icefields Parkway. Pyramid Mountain is at left near the town of Jasper. Vega is the bright star at left; the Big Dipper is at right. The image is a stack of 10 exposures for the ground, mean combined to smooth noise and to smooth the water, and one exposure for the sky and aurora. All 15 seconds at ISO 1600 at f2 with the Sigma 20mm lens and Nikon D750.
The Pleiades star cluster and the other stars of Taurus rising above Mount Kerkeslin at Athabasca Falls, in Jasper National Park, Alberta, October 22, 2016. The sky is brightening with the rising waning Moon off frame at left. Some cloud adds star glows and hazy patches to the sky. This is a stack of 15 exposures, mean combined to smooth noise, for the ground and one exposure for the sky. All are 25 seconds at f/2 with the Sigma 20mm Art lens and Nikon D750 at ISO 6400. A master dark frame of 12 darks was also stacked in with Difference mode to remove some discolouration.
