This is from a Aurora hunt early February. My last two Aurora images are from the same session.
On a unusually quiet Aurora season this was a really good night. The night was really cold with temperatures somewhere between -15 and -20°C. Adjusting the camera and gear was hard and batteries drained quickly. The back of the camera was covered with ice after my breath froze there while looking through the viewfinder.
The difficult shooting conditions made me shoot this shot slighly out of focus, as adjusting the manual focus in the dark with a fogged up viewfinder was tricky. I tried to minimize the effect by some unsharp mask gymnastics.
