iOptron iAFS3 telescope adapter GSO RC10/12/14/16 and other M117X1

This iOptron iAFS3 telescope adapter is designed to allow secure and precise attachment of the iOptron iAFS3 3-inch Inline Automatic Focuser to telescopes that use the M117×1 threaded interface. It is commonly used with GSO Ritchey-Chrétien telescopes, including the RC10, RC12, RC14, and RC16 models, as well as any optical tube that features the same M117×1 rear thread. The adapter provides a rigid, accurately machined connection, ensuring proper alignment between the focuser and the optical tube assembly. This is especially important for astrophotography, where maintaining stability and minimizing flexure are essential for sharp, consistent imaging.
