In reply to Michael Hood:
One of my scopes has a 1.25" removable eyepiece so i can also use my astronomy eyepieces in it. It also means that the M4/3 T adapters I use with my refractor can be used to mate up a M4/3 camera with the little scope. Unfortunately even though they match up physically I can't find focus and would need to find the shortest tubed T adapter I could buy.
My best option is the same as that of Chris Craggs ( but a lot cheaper). A modern bridge camera can be bought for a couple of hundred quid, the zoom ranges are impressive because of the small sensor. The image quality can suffer because of this but unless you are exhibiting or selling, an A4 limit is good enough for private use, I think. The package is always ready, no changing lenses and worries about dust, more bells and whistles than I will ever learn to use, ( I usually leave it in the " i for idiot" mode).
The two main weaknesses in my particular camera , Lumix FZ82, are that at very long focal lengths the autofocus does seem to hunt around a lot, and there is no B function at all.
