Hi Allan,
I attached the Mak to the telescope via a losmandy dovetail. the mak has one of those celestron dovetail thingos which i can't take off because the screws that hold it on have nuts on the inside of the tube.
So i have attached it via 2 losmandy camera mounts as it has holes for attaching a tripod. Normally I'd use tube rings but my losmandy rings are too small to fit over the scope and celestron dovetail.
in any case my dad has just bought a milling machine so i'll have a crack at making my own rings that are big enough to fit. Failing that I have asked moonlite to make me a custom focuser which will allow me to thread the camera directly to it. which is why i was asking about OAG's as i would make/buy adapters to thread each directly to minimize flexure
