I never dared to hope that northern lights would be that active in the infrared – and that beautiful. Taking photos in the surprisingly rough sea of the Atlantic was a special kind of challenge in of itself, but I came prepared. Every image is a composite of 8-16 0.3s frames, which were then aligned and averaged. Rejecting outliers per pixel before averaging means that I could even use a few blurred imaged in order to reduce noise in the background.
