A 360° panorama of the entire sky over the historic and pioneer Larson Ranch site in the Frenchman River Valley in Grasslands National Park, Saskatchewan, Canada. Grasslands in a Dark Sky Preserve and from most of the Park no lights at all can be seen and none light the sky. This is the natural sky, complete with colourful sky glows. The clouds here look dark, silhouettted against at sky lit only by natural sources: the stars, the Milky Way, the aurora at right, and a general airglow tinting the sky green to the north at right, with some red bands of airglow at left to the south. All ground illumination here is from these natural night light sources. The Milky Way was arching overhead when I shot this, so in this “equirectangular” projection it stretches up from the south at left of centre and spreads out across the top of the frame then descends to the northeast at right. The Pleiades is rising at lower right and at upper right is the Andromeda Galaxy. The Big Dipper is just right of centre low on the northern horizon. From this latitude of 49° N the Big Dipper is circumpolar. This is a stitch of 32 panels, shot with the iOptron iPano motorized panning mount, each panel being 40 seconds at with the Sigma 24mm lens and Nikon D750 at ISO 6400. Overlap was 35%. Stitched with PTGui.
