A panorama of the arc of Northern Lights seen August 26, 2019 about 11:30 CST from Grasslands National Park, Saskatchewan, from the Two Trees Road. This is looking northeast. The Big Dipper is at far left. Capella is the bright star above the arc, while Perseus is at upper right. The Pleiades are rising at right, above the silhouette of 70 Mile Butte. This was a diffuse grey arc to the eye but the camera picks up the green and red colours from the oxygen emission lines. This is a 5-segment panorama with the 24mm Sigma Art lens at f/2 and Nikon D750 at ISO 3200 for 20 seconds each. Stitched with Photoshop.
