Night Sky Photos

I bought a tripod off Dan the other week and I've been carrying it places since then hoping that I'll be able to take some interesting photos from it. The other night the sky was looking nice with the moon at first quarter and a few clouds about to make things interesting so I got out my camera and had a play. Things were pretty dark so I needed exposures of 30 seconds to a minute to get enough light. Some of the photos were good straight off the camera. Some others weren't but lead to some curious effects after a bit of tinkering. There are a dozen or so pictures here
