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.

The grand sweep of the aurora borelis across the northern and northeastern sky, from Tibbitt Lake near Yellowknife, NWT, on September 8, 2018. The Big Dipper and Polaris are at left; Auriga and Taurus are rising at right, with Capella, Aldebaran and the Pleiades coming up in the east. Cassiopeia and Perseus are at top in the Milky Way. There’s a meteor streaking down at top as well! This is a mean-combined stack of 8 exposures for the ground to smooth noise, and one exposure for the sky, all 15 seconds at f/2.8 with the 12mm Rokinon full-frame fish-eye lens, and Nikon D750 at ISO 6400. This was part of a time-lapse, taken before the arc swept overhead while it was still across the north and east.
