It was a very bright moonlit night and the Northern Lights were on and off. I wanted to get the full breadth of the mountains and lights in the scene so I set up in the middle of a small frozen lake and tried for a 3 frame composite panorama. Unfortunately the wind was gusting to 50 mph and the lights seemed to be in sync with the gusts. When the aurora lit up, the wind picked up. After 4 hours I was about to give up when the aurora came on during a lull in the wind. I grabbed three 10sec exposures. Stitching was done with Panorama Factory.
