The autumn constellations of Perseus, Cassiopeia and Andromeda over Mount Kerkeslin at the Athabasca River Viewpoint on the Icefields Parkway, in Jasper National Park, Alberta. The Andromeda Galaxy is at upper right. The Pleiades are just clearing the mountain top at lower right. Thin clouds add the natural glows around the stars. Illumination is from starlight. This is a stack of 8 exposures, mean combined to smooth noise, for the ground and one exposure for the sky, all 25 seconds at f/2 with the Sigma 20mm lens and Nikon D750 at ISO 6400.
