Hi Jeanette...
I guess my ultimate aim is to attach my camera to the scope and combine my love of photography with my love of astronomy. So the ability to track is a definite requirement.
Since posting my post, I have noticed some very nice images produced with the use of refractor scopes with motorised mounts. I am now down to 60% sure of what I want and this is likely to drop dramatically the longer I learn what is available.
