I have an 8” f5 newt as well , what adapters , extension rings etc did you require between the camera and the 2” focuser barrel to allow you to focus ?
Also I use a Baader MCCP Mk 111 coma corrector with my DSLR and will use it for the proposer cooled OSC as well. The coma corrector would have a bearing on what adapters and extension rings I would need to achieve focus ?

Appreciate any advice on back focus with the cooled OSC

Thanks in advance
