Universal Astro Radian 79mm Tube Ring Pair
Manufacturer Part # UA79RINGS
These split and hinged UA 79mm i.d. optical tube mounting rings are made of solid aluminum, anodized black for long life. They are felt-lined and have a lock lever to lock them on your optical tube. The rings have a 79mm internal diameter designed to fit the Radian 61mm refractor, but will also fit any refractor with a 79mm OD tube. Now some tubes will need a little extra felt, like the Astro-Tech 60ED. Its tube is 76mm, so a quick run to the hobby store and you should be good to go with a nice set of rings. The rings only weigh 5 oz. each.
There are three threaded mounting holes on each side of the rings for mounting on most equatorial mount dovetail plates. The center hole is 1/4"-20 thread, while the outer holes are M6-1.0. The rings also have notches routed out that provide some very nice cable managment options for heaters and such.
