A 210° panorama from southwest to northeast taking in the full sweep of the auroral arcs this night, January 29, 2017 at the Churchill Northern Studies Centre, on the shore of Hudson Bay in Churchill, Manitoba. Orion is at far left. The Pleiades is over CNSC. Arcturus is at right amid a bit of an isolated arc to the east. This is a stitch of 9 segments, each 15 seconds at f/2 with the Sigma 20mm Art lens and Nikon D750 at ISO 3200. Stitched with Adobe Camera Raw.
The autumn stars of the watery constellations of Capricornus, Aquarius, Piscis Austrinus, and Cetus over the Athabasca River and the peaks of the Continental Divide, from the Athabasca River Viewpoint (the “Goats and Glaciers” viewpoint) on the Icefields Parkway, Jasper National Park, Alberta. Illumination is from starlight. Thin cloud provides the natural glows around the stars. This is a stack of 8 exposures for the ground, mean combined to smooth noise, and one exposure for the sky, all 25 seconds at f/2 with the Sigma 20mm Art lens, and Nikon D750 at ISO 6400.
A fairly mild dispay of aurora over the lake at Police Outpost Provincial Park, in southern Alberta, on September 26, 2016, with the stars of Auriga and Taurus rising, including the Pleiades at upper right. The Hyades in Taurus are the most prominent stellar reflections at lower right, in the still water this evening. Capella is the bright star above centre; Aldebaran is at right. This is a stack of 4 x 20 second exposures for the dark ground to smooth noise and one 20-second exposure for the sky and water, all with the 25mm Canon lens at f/2.2 and Canon 6D at ISO 3200. Taken with dark frame LENR on.
