Beautiful set of the best mounting rings I have ever seen for either Tak FSQ or Traveler. Never used. They were $300.00 WITHOUT the Losmandy adapters. I am selling the Rings only (ie. Losmandy adapters are NOT included)
Description from RC optical Systems site:
Machined out of solid 6061 T6 aluminum, our telescope mounting rings are guaranteed not to flex! And since they are machined to fit, they will not damage or scratch your expensive telescope. Rings can be mounted to "Quick Connect" Losmandy DA's (optional) or bolted directly to the telescope (customer to specify) and are available in any size. We also make custom declination mounting plates for your telescope.
