If I do go for an HEQ5 mount, am I able to put a 10" scope on it? Or am I better off with an 8" anyway? (I've forgotten all I learned about focal length, speed etc, so should probably do a little homework!)
Also, would the camera Russel mentioned work for deep space as well?
Thanks again guys.

No worries Andrew
I don't think you will get a 10" on a HEQ5, (happy to be proven wrong by someone who would know better) you would on an NEQ6, i have even seen 12" on NEQ6 but these were perfectly balanced in no wind.
i think it is possible to do deep sky imaging with that camera but probably not ideal its really meant for planetary - and it excels at it. you could have the specialist planetary camera then perhaps grab an old second hand canon for a couple hundred. if you wanted a two in one, i'd suggest the canon 550d its got good video capabilities and can be used for deep sky.
another thing to consider if you're not really doing too much deep sky you can still nab the brighter objects on the goto dob for example here is the eagle neb i took on my 12 goto

i think they were from 20 sec subs at iso 3200.
of course it is tough to get the big aperture planetary scope and deep sky combo on a budget due to the mount constraints. so as you say maybe get a small rigg for deep sky and go for a separate large dob later.
