I have an 18" classic and not the UC.? I used the Telrad by itself for about 13 years until I got tired of trying to center planets on an imaging chip with a Telrad - it is just not precise enough at a long focal length.? I put on a 13x80 RACI Stellarvue finder that I got from Dave K, and it has really increased by enjoyment of observing with the scope, why did I wait so long to get it?? The 13x80 is a big finderscope, easy to mount on a Classic but might be more problematic with the UC which is probably less forgiving than a Classic balance-wise.
