Thanks for the comments Russell, Phil and Paul, yeah there are a few spots I have still on the hit list down the coast, at least I checked out these for when the next big aurora occurs. Focus in the 6D with a 14mm lens is tough but something I've been looking to improve.
Paul simply mounted on tripod, no tracking the exposure times are kept short enough to avoid star trailing, in fact you can make out the tripod in the 2nd shot. There was another shot with my shadow in frame as well but managed to set the 10 sec timer and move out of the way quick enough
