Compatibility

Featuring identical OPTEC-4300 mechanical interfaces front and back, the Gemini can be easily fitted to most any large telescope OTA. Recessed oval point setscrews provide three-point direct contact with the heavy wall OPTEC-4300 dovetail mount. Gemini's clear aperture of 3.75" is maintained through each adapter, passing even large light cones through to the camera image plane without vignetting.

On the camera side, the Gemini package now includes our # 19830 OPTEC-4300 to DSI threaded adapter. This part converts the camera side to a receiver for any of our Optec-DSI 3.5 High Performance spacers configurable to 1/4" increments when additional back-focus spacing is needed.

Currently designed telescope adapters include support for the AG Optical iDK's, Celestron , Ceravolo Optical Systems Astrographs, Meade 16-inch class SCT, Plane Wave Secure-Fit, and Takahashi telescopes.

Additional adapters available through PreciseParts .
