I'm going to be in Hawaii in a few weeks, and I've always wanted to go see the observatory at Mauna Kea...I don't know if they let the public look through the telescopes there or not, but it will be epic regardless I'm sure. I'm going to be taking my DSLR with me, but I'm a total n00b and take all my pics on auto Any tips on taking night shots of the sky? I will have a tripod with me.
