Went out tonight to take some photos of the northern lights. Had to fight an ice fog that muted the brightness of the lights but I managed to get a couple of nice shots. I think the red is a reflection of the hamlet lights that are behind a hill and 2 km away. The red wasn't noticeable when we were there and I was using exposures of 60 seconds that probably picked up the hamlet reflection.
I finally got a photo with the Aura Borealis across the Orion constellation.
