Between the focuser of the William Optics Megrez80 and my Audine CCD camera there is a William Optics extender tube with a male T-mount thread at one end (that screws into the front of the Audine) and the usual stepped arrangement at the other end that slides into the focuser and is held by the nifty WO clamp. This tube adds about two inches to the light path, and it is too much. What I need is an similarl extender which is two inches shorter. William Optics don't make one, but I saw, once, exactly what I wanted somewhere from Real Technology. I haven't been able to find it since. Does anyone know of it? I can't find it on the Real Technology site.
