Hi all, I'm going to Norway in a weeks time to see the Northern Lights. I have a Nikon D3100 which I shall be taking with me. I've had the camera for a while but I'm still very new (novice) to photography so could anyone help me with the best and desired settings in order for me to get some decent pictures? I also have a tripod which I believe is essential to keep the camera still and also recently got a remote shutter which is cabled as batteries will most likely freeze on a wireless one. Would I need another lens as I only have the one it came with? Thanks in advance.
