The Aurora Borealis are so amazing, on a dark night in Alberta they totally light up the sky. Away from the city lights they produce a sight that just can't be replicated by man. I'm fortunate that have been out a lot lately and I have the opportunity to photograph them. Nikon D800, Nikon 14-24 2.8 lens, f/2.8, ISO 800, 15 second exposure. Sherry Christensen
