Cold night under northern lights in northern Iceland

Walking in a snowy mountain under northern lights in northern Iceland on a Saturday night is my idea of a quality time. No moonlight but clear sky and bright stars all around. For some reason light pollution is the main problem when photographing stars. By walking up the mountain I got rid of most of the light pollution and had a great time taking few frames on the Nikon D3 with both 16-35, 14-24 and 24-70 lenses. Most of the photos are taken on 3200-6400 iso at 15-30 seconds. (Gallery)
