One pair of Vixen cast aluminum guide scope rings in excellent condition, to be used with any 60mm refractor as a guide. These fit on top of any tube ring that has a 1/4" thread bolts on top (such as Vixen tube rings do). Orion carried these for $50.00 new. I'll sell mine for $37.00 shipped to the lower 48 states. I also have an Orion 60mm OTA f/11 available if interested. We can work out a package.
