Northern Circumpolar Constellations over Prairie Landscape (July 12, 2013).jpg
Looking north July 12, 2013 from the Log Cabin at Reesor Ranch, at 3 am as morning twilight was beginning to brighten and blue the northern sky. A faint aurora glows along the horizon. This is a stack of 5 x 2 minute tracked exposures with the foreground from one of the exposures to minimize blurring. With the Canon 5D MkII at ISO 1600 and 14mm Samyang 14mm lens at f/2.8.
