The Northern Lights on February 18, 2015 as shot from the Churchill Northern Studies Centre, in Churchill, Manitoba, photographed with an 8mm fish-eye lens to capture most of the sky and multiple curtains of aurora from northeast (bottom) to west (at left). Note the faint aurora at top separated from the main bright curtains by a darker region, and with darker “holes” in this fainter background. This is a 15-second exposure at f/3.5 and ISO 4000 with the Canon 6D. It is one frame of a 500-frame time-lapse.
