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.
A display of Northern Lights starting up in the twilight, over the river leading out of Tibbitt Lake, at the end of the Ingraham Trail near Yellowknife NWT, on September 8, 2018. This was the start of a fabulous display this night. Capella and Auriga are at left; the Pleiades is rising left of centre; the Andromeda Galaxy is at top. This is a mean-combined stack of 7 exposures for the ground to smooth noise and one exposure for the sky and partially for the reflection, all 25 seconds at f/2.5 with the 14mm Sigma Art lens and Nikon D750 at ISO 1600.
A 360° panorama of the Northern Lights on a partly cloudy night from a site west of Yellowknife on Highway 3. A short-lived arc appears at centre south of the main auroral arc that looks very much like a classic STEVE arc. It appeared for a while in the east then brightened overhead then into the west at left, but was present for no more than about 10 minutes. Whether this was STEVE is unknown. However, Steve is in the picture as friend Stephen Bedingfield is taking images at right. To the left of Steve the person is Mars the planet just on the horizon (but as high as would get from this latitude of 62° N) and the Milky Way. The Big Dipper is at left. This is a stitch of 12 segments, each 25 seconds at f/1.8 with the Sigma 14mm Art lens and Nikon D750 at ISO 3200. Stitched with PTGui — ACR did a good job but did not allow adjusting the framing.
