Astro-Physics Tube ringes with 4.7“ and 5.5“ (120mm, 140mm) diameter

Astro-Physics Tube rings with 4,7“and 5,5“(120mm, 140m) diameter

Astro-Physics tube rings attach to the mounting plate and hold your tube assembly firmly in place. The tops of the rings are 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.

Bottom of rings: Drilled and tapped for 1/4-20 screws for connection to Astro Physics mounting plates. Detailed schematic of the Ring Hole Pattern. There are also internal threads on the top of the rings for attaching accessories.

Please order the size that corresponds to the outside diameter of your tube assembly.
