On my C9.25 mirror shift is quite small and unobjectionable. None the less, I have fitted a motorized Crayford Focuser (JMI model) so that once I have got good focus with the Celestron focus knob; I then use the JMI for fine focusing.

My C9.25 back can accept 1 ¼” and 2” fittings with the correct adapters. I think that the C9.25 opening is around 45mm plus, as I believe that the SCT thread is a 2” (50mm) thread?

My C9.25 has the full length CGE dovetail which is the Losmandy style dovetail, although it also comes with the (narrower) Vixen style full length dovetail.

Cheers

Dennis
