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.
