Northern Nights

So...first entry - had to start with a corker. This was the first time I used the new camera to shoot the northern lights - came out a bit grainy..ISO too high maybe? Also I think a 20s exposure was a little over the top (especially considering in some shots you can see the lights from the airport 40km away!). But all in all, not a bad first attempt...and there'll be alot of chances to improve this winter.
