An aurora and the autymn Milky Way over the Badlands of Dinosaur Provincial Park, Alberta, on September 11, 2015. The stars, constellations and Milky Way of the autumn and early winter sky are rising in the northeast, including the objects: the Andromeda Galaxy at top, and the Pleiades at bottom. This is one frame from a 200-frame time-lapse sequence, though in this image the ground comes from a Mean Combine stack of 7 images to smooth noise but the sky is from one image, each 30 seconds at f/2.8 with the Rokinon 14mm lens and Canon 5D MkII at ISO 3200 on a dark moonless night.
