The SCT is one of the hardest to image with for long exposures. You just about have to have an Off Axis Guider and even then the long focal length makes it tough. Plus you have to have a camera with the right size pixels for it to work well, which may not be the camera you have or want.
I would suggest a fast telescope, such as a 3-4" f/6 or f/7 refractor and a GEM mount.
