It is rated to lift a 6 kg payload straight up without slipping.

The bearing system uses unbreakable instrument-grade roller bearings instead of simpler ball bearings, with no Teflon pads anywhere, running on ultra-hard subzero-coated bearing races that are precision milled and much harder than anodizing or stainless steel.\u003c\/p\u003e\n\u003cp\u003eBy factory default the pressure screw, which sets the contact pressure between the diamond-coated axis and the steel plate, holds up to 6 kg of lifting force; Baader chose this setting for photographic use. You can tighten it further, but the focuser will then run less smoothly, or loosen it for visual use to make it run even more smoothly. Baader adds that the focusers are rigid and slip-proof without a locking screw pressing on the tube or drive plate, so motor focusers can be used at any time without tipping the image plane, and the zero-shift locking knob stops any movement without affecting the optical axis adjustment.\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\u003e40 mm Travel, 1:10 Fine Focus and Rotation\u003c\/h3\u003e\n\u003cp\u003eThe BDS-NT has 40 mm of focus travel and an engraved index scale from 0 to 40 mm in 1 mm steps.

The detachable drive block is reversible for right- or left-hand fine-focus operation: remove the four marked screws with a 2.5 mm Allen wrench, rotate the block by 180°, refit the screws carefully, then check the alignment and that the focuser runs as smoothly as before.\u003c\/p\u003e\n\u003cp\u003eThe focuser can be removed from or rotated on the VersaBase by loosening the eight M3 hex screws (two on each side), which need a 1.5 mm Allen wrench (not included).\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\u003eTelescope Connection: S88 Dovetail and VersaBase\u003c\/h3\u003e\n\u003cp\u003eThe BDS-NT ships with the Baader VersaBase, which fits most tube diameters of 200 mm and larger.

micro-geared diamond drive, 80 mm of focus travel, a 1:10 fine focus and an oversized 55 mm clear inner diameter. It is rated to lift a 6 kg payload straight up without slipping.

The bearing system uses unbreakable instrument-grade roller bearings instead of simpler ball bearings, with no Teflon pads anywhere, running on ultra-hard subzero-coated bearing races that are precision milled and much harder than anodizing or stainless steel.\u003c\/p\u003e\n\u003cp\u003eThe 1:10 stainless-steel fine-focus mechanism moves the drawtube about 2 mm per turn of the fine knob, against about 22 mm per turn of the coarse knob. The detachable drive block is reversible for right- or left-hand fine-focus operation: remove the four marked screws with a 2.5 mm Allen wrench, rotate the block by 180°, refit the screws carefully, then check the alignment and that the focuser runs as smoothly as before.\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\u003e80 mm Travel, Load Setting and Drawtube\u003c\/h3\u003e\n\u003cp\u003eThe BDS-RT provides a generous 80 mm of focus travel, marked by an engraved 1 mm index scale for repeatable measurements. The focuser is rotatable. By factory default the pressure screw, which sets the contact pressure between the diamond-coated axis and the steel plate, holds up to 6 kg of lifting force; this setting was chosen for photographic use. You can tighten it further, but the focuser will then run less smoothly, or loosen it for visual use to make it run even more smoothly. The focusers are also rigid and slip-proof without a locking screw pressing on the tube or drive plate, so motor focusers can be used at any time without tipping the image plane, and the zero-shift locking knob stops any movement without affecting the optical axis adjustment.\u003c\/p\u003e\n\u003cp\u003eThe drawtube itself is built for rigidity. Each of its roller bearings is individually adjustable for precise alignment of the mechanical and optical axes, and they run on ultra-hard subzero-coated bearing races. The oversized 55 mm tube has anti-reflection knife-edge baffles to prevent vignetting.

Every BDS is aligned at the factory to be square to its mounting base, and most users will find this sufficient with most commercially produced telescopes, particularly visual observers, for whom the procedure is not recommended. The adjustment works through bearing adjustment screws around a pivot point on the bearing block; read the instructions completely first, make only small adjustments, and attach no heavy accessories during the first attempt, since the drawtube is loose and could slip.\u003c\/p\u003e\n\u003cp\u003eUse a \u003ca href=\"\/collections\/collimation-tools\"\u003elaser collimator\u003c\/a\u003e such as the Baader Mark III LaserColli (#2450343) to monitor the adjustment, and metric hex keys of 2, 2.5 and 4 mm.

Because it uses a direct belt drive with no reduction gearbox, there is zero backlash, a critical factor for autofocusing routines that rely on consistent mechanical response. Pegasus notes that with no gearbox the speed suits moving the primary mirror in or out at very fast rates, and that it makes nearly perfect V-curves easy to achieve. A V-curve is what your autofocus routine draws as it moves from outside focus, through focus and out the other side; clean, symmetrical curves give the software a precise best-focus point.\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\u003eChoosing Your FocusCube Zero: C8, C11, or C14?\u003c\/h3\u003e\n\u003cp\u003ePegasus offers different versions of the FocusCube Zero to match the specific mechanics of various Celestron telescopes.

While the FocusCube Zero bracket is officially designed for Celestron SCTs, Pegasus notes that it has been successfully installed on some Meade SCT telescopes that feature a round focus knob similar to the Celestron design.

SCT14\u003c\/h2\u003e\n\u003cp\u003eThis 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.\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 0.8Kg\/cm Torque\u003c\/h3\u003e\n\u003cp\u003eAt 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.\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\u003eCollision-Free Integration for Celestron 14\" SCTs\u003c\/h3\u003e\n\u003cp\u003eThe 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.\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\u003eMotor Focus Kit Zero: A Necessary Upgrade for SCT Imaging\u003c\/h3\u003e\n\u003cp\u003eThis 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.
