A single image of an aurora at the zenith and to the south above the Churchill Northern Studies Centre in Churchill, Manitoba with a group from Road Scholar taking in the show. This was February 15, 2018. Orion and the winter stars are to the south.
Orion and the winter sky, at left, and a swirl of colourful aurora over the Churchill Northern Studies Centre, in a display on February 11, 2018. People from the first Learning Vacations group of the season are shooting the Lights. This is a single image with the 12mm Rokinon full-frame fish-eye lens and Nikon D750.
Orion and the winter stars, including Sirius and Procyon, on a clear winter night in downtown Calgary and shining over the pedestrian Peace Bridge over the Bow River. I shot this on January 20, 2018. This is a real scene, though the sky is a single longer exposure of 13 seconds, while the ground is a blend of 4 exposures from 2 to 8 seconds, all at ISO 100 and f/2.8 with the 14mm Sigma Art lens and Nikon D750. No light pollution reduction filter was used here, as none fit over the large lens of the 14. The ground images were blended with luminosity masks generated with ADP Pro v3, to prevent the lights on the bridge from blowing out too much. Star diffraction spikes added with Astronomy Tools actions.
