I purchased the above telescope, a Voyager mount, and a box of misc. rings and dovetail plates at an estate auction recently. I have been using a set of guide scope rings to mount the telescope on the mount but I want to get a set of hinged rings that are easier to set-up and take-down. The OD of the tube is 90mm. I've been looking at different options and I'm wondering if anyone has any opinions? The ring sets i have seen vary from $40 to $140+. I bought a Telrad finder to mount once I get a set of rings. Thanks for any help offered.
