The entire assembly, including the specialized bracket, weighs only 280g and operates reliably in temperatures from -40°C to +80°C. Its pulley-and-belt design ensures your motor doesn't collide with a focal reducer or filter wheel, making it an essential upgrade for remote astrophotography.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eZero-Backlash Focusing with a 1.8° Bipolar Stepper Motor\u003c\/h3\u003e\n\u003cp\u003eThe core of this kit is a high-torque bipolar stepper motor engineered for the fine focus adjustments required in astrophotography. With a 1.8° step angle, the motor can execute extremely small movements for critical focusing, while its 0.8Kg\/cm holding torque is more than sufficient to move the primary mirror of a Celestron SCT without slipping. The belt-driven system completely eliminates the backlash inherent in gear-based focus motors, meaning your autofocus routines run faster and more accurately without the need for software compensation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eUniversal \"Margarita\" Bracket for Celestron SCTs \u0026amp; RASAs\u003c\/h3\u003e\n\u003cp\u003eThe included black anodized aluminum bracket features a unique \"margarita\" design that provides broad compatibility across the Celestron lineup, including Classic SCT, EdgeHD, and RASA models from 6\" to 14\" apertures. This design positions the motor away from the rear cell of the telescope, creating critical clearance for accessories like focal reducers and large filter wheels. The rigid construction prevents flexure, ensuring the motor's precise movements are transferred directly to the focuser knob without any mechanical slop.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat motor controller do I need for this SCT Motor Focus Kit?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThis kit contains the motor and mechanical hardware only.

The kit includes all the necessary screws and hardware to attach the bracket to the telescope's rear cell and mount the motor.
