Beginner needs some advice

First, I'm very impressed with the shots I've found on these pages. I'm part way through buying stuff I need to take some shots of my own. I already have a Canon Digital Rebel, a few lenses, remote shutter release and a big tripod. Will soon be buying a scope, probably a TV85. (Too big, maybe, but my buddy has a Swarovski we can use when my rig is too much.) Here's the question - what should I start out with to mate the scope with the camera? There seems to be lots of different ways to go. I'll figure out what I like eventually, but what would be a good starting point? I don't want to buy a lot of stuff that doesn't really work.
