Jennifer's point is a good one as well Tom in that you need to consider the type of object that you want to image. If it is only planetary work then a web cam or dedicated planetary camera would be the way to go (do a search on DMK cameras). Conversely though, planetary imaging requires long focal length, high magnification work which means that you are working with a narrow field of view. This will require close attention to issues such as mount stability and guiding/tracking accuracy. Registax is a software package that a lot of planetary imagers use.
