completely new and just trying to assemble my setup for the first time.
I have a William optics redact 51 and a Celestron #93419 T-ring. The T-ring comes with an inner 42mm ring easily removed by loosening set screws.
With the T-ring on the camera the threads from the telescope aren't long enough to reach the threaded part of the adapter. What am I missing? Other than I should have sprung for the $32 WO version.
