If you want to use it as a guide scope and even if you can get one with bigger rings, this arrangement might give problems with flexure and balance. The ST80 OTA weighs 1kg, guide camera etc might add another 500g. You'll also have the camera attached to the scope focuser. That's a lot of weight sitting a long way up the tube. You would be much better off mounting it using a vixen style dovetail mount fixed closer to the tube cradle.

Thanks for the information. At the moment it's just theoretical anyway. I'm looking around, reading other people's ideas, and then wondering what I would need to do to make it happen.
Appreciate the help
