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.
A developing auroral arc in the darkening twilight, September 8, 2018, at Tibbitt Lake near Yellowknife, NWT, at the end of the all-weather Ingraham Trail road. The Big Dipper and Arcturus are at left; Capella and the Pleiades are rising at centre; the Andromeda Galaxy is at top right. The aurora developed into a fantastic display later in the night after midnight. This is a panorama of 7 segments, each 30 seconds with the Sigma 14mm Art lens at f/2.2 and Nikon D750 at ISO 1600. Star glows are from the light cloud present. Stitched with Adobe Camera Raw.
The Big Dipper and Arcturus in the evening twilight at Tibbitt Lake on the Ingraham Trail near Yellowknife, NWT on September 8, 2018. This is a single exposure, not HDR, as the HDR produced double stars and odd artifacts on the star images do to their motion. This is 13 seconds at f/2.8 with the Sigma 14mm lens and Nikon D750 at ISO 400.
