Aurora and Twilight at the Old Barn Panorama (June 30, 2019).jpg

Add to Cart Add to Lightbox Download
A 150° panorama of an arc of diffuse aurora to the northeast, and above the glow of solstice twilight to the north at centre, while the urban sky glow from Calgary lights the sky at left to the west, as well as an odd band of cloud that persisted all evening across the north.

This was at the Old Barn site near home.

The aurora has the characteristic green band but with a magenta glow above from high altitude oxygen glowing.

Capella is embedded in the auroral arc, just right of the road which is aimed due north. The W of Cassiopeia is at right, with the Andromeda Galaxy rising below in the northeast, along with the stars of Perseus and Pegasus. Arcturus is at far left over the barn in the west.

This is a crop from an 8-segment panorama with the 24mm Sigma lens and Nikon D750, all segments 30 secconds at f/2 and ISO 800. Stitched with Photoshop Photomerge. ACR refused to stitch the left segments.
