Andrew, you are doing what im going to do. Mount the 10" ontop of a eq6 or something that has a load capacity of 20kg + slip a small fast refractor on the side to guide with and a sensitive mono guide cam and your away. to start off imaging with something cheap, you can go the cannon eos 350D, and get it modded, or there are a heap of decent CCD's out there.
Remember that although the ED 80 is quite good for a starter scope 8cm Vs 25.4 cm the light grab is just so much more, this means that you lower your capture times or increase your faint fuzzy capabilitys. and unless your looking at the 100 - 120 mm apo refractors and the like, the 10 is a good cost effective option.
Just make sure its collminated perfectly for your astro photos hence invest in some good stuff like Cats eye collmination (there are others just look for the threads in the forum)
