I thought it would be overcast tonight but when I was going to sleep I took a look out of a window and could see that the sky were almost clear and the northern lights could been seen. It wasn't hard decision to go out instead of going to bed. The lights were beautiful in spite of the clouds. Camera: Canon EOS 5D Mark II. Lens: Canon 14mm f/2.8L II USM.ISO 1600, 9s exposure.
