Thank you all for the votes!!! I was not sure I was going to be able to get this shot as I stitched 5 images (each 30sec exposures) together and during that time the Aurora was dancing above Lake Scotty in Trapper Creek Alaska... I was very pleased with the result. Camera Settings:
Canon 5D MarkIII/Canon 16-35 2.8 L @ 18mm/ISO 800/30's exp/f 2.8 and mirror lock up enabled
