Have a Discovery 6" reflector with standard 6X30 straight-thru finder. Looking for either (1) a 90 degree adapter for that finder or (2) a right angle finder that'll fit the mount. Tired of back aches. I'll give the old finder to my 11 yr old and deduct from her allowance (juuuust kidding). Anybody got a 90 degree around you want to unload? Thanks for looking - Dave.
