As stated on the Scopestuff website
This compression ring visual back replaces the visual back on
Synta refractors that have 2" draw tubes, like the Orion 80 ED and
102, Vixen ED80SF, Skywatcher SW120ED and Black Diamond 120ED,
125 and 150mm refractors from Orion, Celestron, Skywatcher, TAL,
Antares and others. Fits drawtubes with male threads measuring 2.2"
outside dimension.
Instead of thumbscrews that scratch your diagonal, this unit uses
a brass compression ring to firmly grip the barrel. Lowest possible
profile for the most in-focus possible. Precision CNC machined for
square and centered alignment. Aluminum, black anodized, brass
compression band, nylon thumbscrews. Brass thumbscrews also
available.
Please measure your drawtube male threads to verify they are 2.2"!
