Optec's 4.3-inch circular dovetail adapters are made to the OPTEC-4300 dovetail standard.  These telescope-side adapters will connect most telescopes to the Gemini Focusing Rotator or the TCF-Lynx3 focuser. One side has a telescope-specific thread or dovetail and the other side presents the 4.3-inch diameter Optec dovetail mount. If your scope or accessory is not listed, do not hesitate to call.  We are constantly adding new adapters to our catalog.

If you cannot find the exact stock adapter to fit between your telescope and imaging train components, visit PreciseParts.  The Build-An-Adapter application allows you to select two devices to connect and choose an appropriate length to maintain any back-focus considerations.  Orders are usually filled within a week or so and each adapter is guaranteed to fit.
