Northern Lights, Aurora Borealis

Norhtern Lights, aurora borealis - A very colourful auroral arc at the start of a fine display on September 2, 2016, with purple curtains to the west, at left, still being illuminated by sunlight, and red upper curtains to the east, at right, in darkness. The classic auroral oval shape to the curtains is obvious, especially to the curtains farthest north and lowest in the sky. The Big Dipper is at upper right. Perseus is above centre. The bright star at centre and reflected is Capella. Andromeda is at right. The location is a pond near home in southern Alberta.

This is a 150∞ panorama of 6 segments, each 2.5 second exposures at f/2 with the Sigma 20mm lens and Nikon D750 at ISO 3200. Stitched with PTGui software.
