1. 50 - 60 mm Low Profile Finder Scope Rings

First, I want to say that Stellarvue has the best customer service that I have ever encountered, bar none, excellent. Secondly, the R050AT finder rings and mount are very well made and finished, and allow plenty of adjustment to align the finder scope with the telescope. Please note that if you will be using this mount on a larger diameter telescope tube, you will need to use shims between the mount and the telescope tube in order to avoid bending the mount when it is tightened down firmly. For my 6" telescope tube I used 3 thin flat washers on each of the two screws. My 10x50mm finder scope is also from Stellarvue, and also of exceptional quality. I highly recommend their products.
