Brand new Stellarvue 102 hinged tube rings, 4.125" nominal ID. Brand new in original box, never used. They also fit Meade ETX 90 tube as is, but better with one layer of added felt. Black with 1/4-20 thread top and bottom. New cost was $19 each plus shipping. My price $33 for the pair, firm shipped CONUS. Prefer payment by Money Order. Sorry I don't do PayPal. Please note my Astromart rating. Thanks for looking.
