Wanted, SCT diagonal. I recently purchased a VERY large Speers-WALER 12mm eyepiece and I am not convinced that the normal 1.25 inch Visual Back and 1.25 inch diagonal will offer enough support. But I do feel that a SCT diagonal that threads onto the rear cell will. If you have one you no longer need, or are selling one to "move up" to something else, please respond with description and price. Either a 2 inch SCT diagonal with 1.25 inch adapter, or a 1.25 inch SCT diagonal will do.
Thanks, Fred Hoefler
