A curtain of aurora sweeps over the houseboats moored on Yellowknife Bay in Yellowknife, NWT, on September 11, 2018. The Pleiades and Hyades star clusters in Taurus are rising at left. This is a mean-combined stack of 8 images to smooth noise for the ground and water, and a single exposure for the sky and houseboats themselves (as they were moving slightly from exposure to exposure). Each was 13 seconds at f/2 with the Venus Optics 15mm lens and Sony a7III at ISO 3200.
A bright arc of aurora over the still waters of Tibbitt Lake, at the end of the Ingraham Trail all-weather road east of Yellowknife, NWT. This was the night of September 8/9, 2018 during a very fine display. Vega and Altair and the Milky Way are at left. The Big Dipper and Polaris are at right. This is a single exposure for the sky, and a mean-stacked blend of 5 exposures for the ground and water to smooth noise. All are 6 seconds at f/2.8 with the Rokinon 12mm full-frame fish-eye lens on the Nikon D750 at ISO 6400.
A 180° panorama of a developing aurora display near Yellowknife, NWT, at Tibbit Lake. This was September 8, 2018. The Kp Index was officially only 2! Yet the display developed into one of the best I have seen. This was early, as the arcs began to come overhead. The Big Dipper is left of centre to the northwest. Arcturus is reflected in the water. Capella is at centre amid the lower curtain, rising in the northeast. Vega is at upper left. The horizon glow at far left is Yellowknife about 70km away. This is a stitch of 8 segments, each 25 seconds with the 14mm Sigma Art lens at f/2.2, mounted portrait, and on the Nikon D750 at ISO 3200. Stitched with Adobe Camera Raw.
