  • Optec 12.5mm 4300 Dovetail (Gemini) Extension

    The Optec 4300 circular Dovetail mount is meant to be used for certain OEM version TCF 3" focusers, and with the Gemini Focusing Rotator. One side presents the telescope specific Dovetail or thread, and the other presents the 4.3" diameter Optec Dovetail mount. This is a 12.5mm Extension for use with scope-focuser adapters, in cases where you need more space between the focuser and the scope, and the adapter is too small. With how huge the Gemini Focusing Rotator is, this is a suprisingly common issue! This one is specifically sized at 12.5mm. OP-19829
