Celestron C6 users.

May I ask advice please. I once had a Nestar 6 SE orange tube C6. I removed the standard Celestron 1 1/4" visual back and fitted an S C T Baader Clicklock. This worked well. I am now buying a silver colouered C6 from a Nexstar Evoultion. I'm not sure that there is a Clicklock that will fit this visual back thread.

Can I ask other C6 users how you have upgraded the visual back on your C6 OTA please?

I would of thought they're all the same, it doesn't make sense to make each one different as it'll cost more to manufacture and stock different items. Mine is the black OTA, the standard VB is the 1.25. I have a 2 inch Celestron VB adaptor which replaces the 1.25 if I want to use my 2 inch diagonal, it's just a tube that the diagonal pushes into with lock screws to hold it in place.

I believe all Celestron SCTs from 5" to 10" use the same visual back size.  The C11 and C14 are larger, IIRC.

You may be right.

I had a silver 6” Nexstar evolution and the Baader SCT visual back securing thread was too narrow so it would not tighten up BUT that was the non clicklock version I think.
