  • Pegasus Astro SCT Bracket, Pulley, Belt, Bolts Kit for SCT14

    This SCT Bracket Kit provides the core mechanical components to achieve automated, zero-backlash focusing on your Celestron 14" telescope. The system's bipolar stepper motor delivers 0.8Kg/cm of holding torque to precisely move the primary mirror without slipping, and the entire assembly, including the rigid bracket, weighs only 280g. This kit includes the specific 22mm bore pulley required for Celestron's 11" and 14" optical tubes, ensuring a perfect fit for large-aperture instruments.

    Zero-Backlash Focusing with 0.8Kg/cm Torque

    At the heart of this kit is a powerful bipolar stepper motor engineered for zero backlash, a critical requirement for astrophotography. This eliminates focus slop, ensuring that your autofocus routines land on the exact same point every time, regardless of direction. With a holding torque of 0.8Kg/cm, the motor has more than enough strength to overcome the inertia and resistance of a large SCT primary mirror, providing crisp, repeatable focus adjustments all night long.

    Collision-Free Integration for Celestron 14" SCTs

    The system's intelligent design uses a pulley and belt to offset the motor from the rear cell of the telescope. This seemingly simple choice is a critical feature for imagers using focal reducers and large filter wheels, as it creates valuable clearance and prevents mechanical collisions. The included black-anodized aluminum "Margarita" bracket is engineered for maximum rigidity to prevent flexure, and this specific kit provides the 22mm bore pulley and correct length belt for a secure fit on Celestron 14" SCT, EdgeHD, and RASA models.

    Motor Focus Kit Zero: A Necessary Upgrade for SCT Imaging

    This kit is a component of the Motor Focus Kit Zero system, which replaces older, slower motor designs. The upgrade to a zero-backlash stepper motor is not just an incremental improvement; it's a fundamental change that enables modern imaging techniques. Unlike previous models, the Zero motor is fast enough for rapid autofocus runs and precise enough for the fine-scale adjustments demanded by high-resolution planetary imaging or deep-sky astrophotography. Please note that this kit requires a compatible Pegasus Astro motor controller, such as the Dual Motor Focus Controller or Ultimate Powerbox v2, to operate.

  • What controller do I need for the SCT Bracket, Pulley, Belt, Bolts Kit for SCT14?

    This kit contains the mechanical components and motor but requires an external controller for power and logic. You will need a compatible Pegasus Astro controller, such as the Dual Motor Focus Controller, eXternal Motor Controller, or an Ultimate Powerbox v2 (or newer).

    Will this SCT Bracket Kit fit my older Celestron 14" SCT?

    The "Margarita" style bracket is designed for modern Celestron SCT, EdgeHD, and RASA telescopes. While it fits a wide range of models, some very old Celestron scopes may have a different focuser knob assembly. If you are uncertain, it is best to compare your telescope's focuser to the product images or contact us for confirmation.

    Why use a belt and pulley system for the SCT14 focuser?

    The belt-driven design intentionally places the motor to the side of the focuser shaft. This creates crucial clearance space at the rear of the telescope, preventing the motor from colliding with other equipment in your imaging train, such as a large filter wheel, off-axis guider, or focal reducer.

    Can I use this SCT Bracket Kit on my Meade 14" LX200?

    While designed and tested for Celestron telescopes, the bracket has been found to fit some Meade SCT models that use a similar round focuser knob. Compatibility is not guaranteed. Please carefully check the product photos against your Meade's focuser assembly before purchasing.

    How does the zero-backlash motor in this SCT kit improve my images of Jupiter?

    When imaging Jupiter at high magnification, achieving perfect focus is critical and changes constantly due to atmospheric seeing. A zero-backlash motor allows your software to make tiny, precise, and repeatable adjustments to the focus. This means you spend less time fighting mechanical slop and more time capturing sharp data during moments of steady air.

    Is the 0.8Kg/cm motor strong enough to move the mirror on a Celestron 14" EdgeHD?

    Yes. The 0.8Kg/cm of holding torque is ample for moving the large primary mirror of a C14 or EdgeHD 1400. This ensures that focus adjustments are direct and immediate, without motor stalls or slippage, even when moving the heavy mirror against gravity.
