Does anyone know where I can pick up a quality hybrid diagonal so that I can use my 1.25" eyepieces in a old classic scope that has a .965 focuser? I ordered one from Orion but the housing is made of plastic and the .965 barrel end is too loose of a fit in my focuser so that it's having collimation issues. The original .965 prism diagonal is actually pretty usable and is better than the Orion but I can't find any decent .965 eyepieces either. I sent e-mails to Hands On Optics and Apogee both who have the hybrid listed on their web sites to find out if their version was also made of plastic or perhaps is even the same exact diagonal that Orion sells but have not received a reply from either one. Also what is preferred for this application, a mirror or prism diagonal? Any help is much appreciated.
