Re: OTA upgrade advice wanted
I had a standard C11 and went to a C14HD. noticeable difference in flat field performance. The C14 has some issues with focus and mirror flop so I would recommend using an OAG. I'm not sure if others

Re: C11 Edge HD and SBIG STT-8300M
The SBIG is a standard 17mm spacer so the camera shouldn't matter. All Celestron Edge telescopes require specific spacing to you camera. If you are running at native focal ration, you will need to get

Re: Hello
I have no issues finding a 3.25" adapter I just thought the focuser would be an issue with the limited back focus but after looking at the one your using I think I may be fine as it looks a lot longer
