Thread on the back of a 1980 dynamax 8 SCT
I recently acquired an 8” criterion dynamax SCT and would like to know the thread type on the rear of the telescope so I can get an adapter to attach a
celestron or Meade 1.25” visual back. The visual back I have is showing it’s age.
Optically it’s fairly good and I’ve heard all the problems associated with this scope.
Grateful for any advice , regards philip
