Hey, in the end of February I am going to Tromsø, Norway for a couple of days. On that occasion I would like to try to snap a couple of pictures of northern lights (weather permitting). Since I have next to non experience with night sky photography (even haven't seen a northern light personally, yet), I am looking for a good tutorial or tips. I already googled and found some. Various pages, however, have contradicting information on them (high vs. low f-stop, using higher ISO vs. lowest, ...). Does any of you can recommend a good tutorial? I know, it is a bit much to ask, but I give it a shot anyway: Has anyone of you been to the Tromsø area and can give tips for nice spots to see and photograph the northern lights (I will have a car)?
