For photography with a telescope, I'd recommend a digital SLR for the simple fact that the camera's exposure meter may not work and you need to make the exposures in manual mode. With a digital SLR you can make as many test exposures as you like and delete the bad ones.

Having said that, some digital cameras limit the maximum length of exposure you can make (or will run out of battery power during a really long exposure in the cold). For maximum flexibility you could go to the opposite extreme and try an old fashioned completely manual film camera. You can prop open a manual shutter for as long as you like.

By the way, although we're talking about coupling up a camera to a telescope, you may very well get the best photographs by attaching the camera to the side of a telescope (with a "piggy back" mount) and just using its drive mechanism to track the stars.
