Weighing only 280g including its bracket, this system operates reliably in a wide temperature range from -40 °C to +80 °C, ensuring precise focus adjustments through any imaging session.\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 0.8 Kg\/cm of Torque\u003c\/h3\u003e\n\u003cp\u003eAt the heart of this kit is a powerful bipolar stepper motor engineered for the demands of automated focusing. The zero-backlash design eliminates mechanical play, ensuring that every command from your controller results in exact, repeatable focuser movement, a critical requirement for sharp stars. With a holding torque of 0.8 Kg\/cm, the motor has ample strength to move the primary mirror of a Celestron 11\" SCT without slipping, even when the telescope is pointed near the zenith.\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\u003eSCT Margarita Bracket for Collision-Free Imaging\u003c\/h3\u003e\n\u003cp\u003eThe included black anodized aluminum \"Margarita\" style bracket is specifically designed for Celestron SCTs, providing a rigid, flex-free mounting platform. The pulley-and-belt drive system is a key design feature that positions the motor away from the rear cell of the telescope. This creates essential clearance for filter wheels and other accessories, preventing collisions that can occur with direct-drive focus motors, especially when using a focal reducer.\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\u003eSystem Integration: Required Pegasus Astro Motor Controllers\u003c\/h3\u003e\n\u003cp\u003eThis kit contains the mechanical motor and bracket assembly required for automating your SCT's focuser. To operate it, you must connect it to a compatible Pegasus Astro motor controller (sold separately).

The primary advantage of the Zero design is its combination of speed and precision. The motor is significantly faster than previous generations, allowing your autofocus routine to complete more quickly, and the zero-backlash mechanics provide a higher degree of accuracy for critical focusing on planetary and deep-sky targets.\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\"\u003eDoes this SCT Motor Focus Kit work with my Celestron EdgeHD 11\"?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, this kit is fully compatible with both the classic Celestron 11\" SCT and the EdgeHD 11\" models.

By offsetting the motor from the focuser knob, it creates significant clearance at the rear of the telescope.
