The other option is adapters that allow you to connect your SLR directly into the eye-piece holder of the telescope...this involves long exposures and very accurate tracking of the astronomical objects movement through the sky. I think these adapters require removing the SLR lens? But if you are getting such nice results with hand-holding, I bet you could rig something up with PVC pipe to hold your digital in place. Always wanted to try something like this, but too much light pollution in Chicago to make it worthwhile.
