Seven precise stand-off spacers maintain the 2.2\" separation of these plates.  The rotating drawtube is moved linearly with 1\/2\" of total travel using a premium timing belt driven by a high torque stepper motor.  The entire package is accented with a beautiful carbon fiber wrap.  Dual RJ45 connectors provide connection to the Gemini Control hub.  The independent rotating drawtube is supported by a custom X-cage bearing system supported by large, 6mm chrome ball bearings. \u003c\/p\u003e\u003ch3\u003eSpecifications for Gemini and Controller:\u003c\/h3\u003e\u003ch5\u003eFocusing Rotator Physical Specifications:\u003c\/h5\u003e\u003cul class=\"text-left\"\u003e\n\u003cli\u003eClear Aperture: 3.75\" (95mm)\u003c\/li\u003e\n\u003cli\u003eBack-Focus Usage: 2.2\" to 2.7\" (55.9 to 68.6mm)\u003c\/li\u003e\n\u003cli\u003eFocuser Travel: 0.5\" (12.7mm)\u003c\/li\u003e\n\u003cli\u003eFocuser Resolution: 0.11 microns per step\u003c\/li\u003e\n\u003cli\u003eRotator Resolution: 600 steps per degree\u003c\/li\u003e\n\u003cli\u003eMinimum Overall Thickness: 2.2\" (55.9mm) [Full IN position]\u003c\/li\u003e\n\u003cli\u003eDimensions: 9.4\" x 7.4\" (239mm x 187mm)\u003c\/li\u003e\n\u003cli\u003eWeight: 6 lb. 6 oz.
