A 180° panorama of the display of Northern Lights on August 31/September 1, 2016, as seen from the rock “moraine” hill overlooking Moraine Lake, in Banff National Park, Alberta, but looking north to the Lights down Desolation Valley. The Tower of Babel cliff face is to the right. Note the faint curtains to the left and right – an isolated arc was visible overhead as part of these curtains in the east and west. This was New Moon night, as later this night (in Alberta time) there was an annular eclipse of the Sun seen from Africa. This is a stitch of 7 segments with the 20mm Sigma Art lens at f/2 and each for 10-second exposures with the Nikon D750 at ISO 3200. Stitched with PTGui — Camera Raw and Photoshop didn’t work well for this pan.
The arc of Northern Lights starting a show in the deep twilight over Prelude Lake on the Ingraham Trail near Yellowknife, NWT. This was September 9, 2019. Light from the waxing gibbous Moon behind the camera also illumimates the scene. The autumn colours make for a good contrast with the sky colours. This was from the lookout point above the lake and main parking area and boat launch. The Big Dipper is at left; Capella is at centre; the Pleiades and Hyades are rising at right of centre. This is a 5-segment panorama with the 15mm Laowa lens at f/2 and Sony a7III at ISO 800 and all at 25 seconds. Stitched with PTGui, as ACR and Photoshop refused to joint the left segments.
April 17/18, 2001 aurora, taken from home in Alberta. Looking straight up at zenith. 28mm wide-angle lens at f/2.8 Fujichrome Provia 100F slide film (ultra-fine grained, the finest on the market) exposure 40 seconds. Colors and contrast punched up but not excessively. Taken near the peak of substorm burst which started at midnight and lasted about 10 minutes. This aurora was the result of a major flare that let off on the Sun on Easter Sunday. Big Dipper at top, and zenith point below it
