Astro-Physics 65RING Mounting Rings
Mounting rings attach to the cradle plate of the mount and hold your tube assembly firmly in place.
The tops of the rings are also flat which allows you to support your guidescope, camera or other accessories. The rings feature a hinged assembly with thumbscrew closure. They are felt-lined to prevent marring of your tube. Please order the size that corresponds to the outside diameter of your tube assembly.
