Celestron CPC1100 back focus distance.
Hi everyone. just after a bit of help. I'm trying to find the correct back focus distance from the outer edge of the baffle lock nut to the camera focal plane.
I know for the CPC1100 EdgeHD it's 146mm, but don't know if it's the same for the standard CPC1100 GPS.

Any help appreciated.
Cheers
