Excellent mick, you're hooked already
Agree with the others, for lunar/planetary, the ToUcam is the best choice. For deepspace, a DSLR is usually the preferred option, unless you can afford a dedicated commercial astro CCD camera. A cheaper option than the DSLR is to get a long-exposure modified ToUcam, or even a DSI for $500.
Good luck!
btw here's a quick reprocess..
You should try a faster shutter speed on your moon shots, to avoid over-exposing the light areas like you see on the RHS. It's very addictive!
