Sorry it took me a while to reply, a Mod moved my post from another thread and I only just spotted it.
So should I assume the Celestron mounts take Vixen Dovetails, as IIRC my C5 has screws designed to attach to one of those... see bottom left in image.
The Celestron support person I've been talking to said it should attach to a Nexstar 6/8 SE mount and, if I understand correctly, via a Vixen bar, but I wasn't sure if the mount had a Dovetail or it screwed in place:
Oh and I can't see any sign of the mounts being sold stand-alone in the U.K., so worth asking how well they are thought of as sending one back to the U.S. would be expensive and claiming back Import Duty and Tax very tricky?
Also is there another quite small/light computerised mount that would play nice with it? I have bigger mounts, but want something to take to City Centre Star Parties where finding stuff can be quite a chore (as the City is London and sometimes you can see one star in 1/4 of the Sky) and quite a bit of walking/carrying is involved.
