Its high-torque design can lift over 6 kg of imaging equipment, while the included set of five motor couplers accommodates nearly any focuser shaft from 4mm to 8mm.

With a precise step size of 0.06 degrees, you can achieve critical focus that is essential for high-resolution planetary imaging or teasing out the finest details in faint deep-sky objects. The motor's gearbox generates enough torque to lift more than 6 kg, easily handling heavy image trains with large cameras, filter wheels, and off-axis guiders without slipping. The low-backlash design ensures that autofocus routines run accurately, with any minimal play easily managed by standard imaging software.\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 L-Bracket: Adapts to Nearly Any Focuser\u003c\/h3\u003e\n\u003cp\u003ePhysical compatibility is solved with a robust, black-anodized aluminum L-shaped bracket that resists flexure under load. The bracket features multiple slotted rails, allowing you to position the motor perfectly for alignment with your focuser's shaft. For low-profile focusers, such as those found on many Newtonian reflectors, the standard lower part of the bracket can be swapped for an included slimmer rail, ensuring a perfect fit without adding unnecessary height.\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\u003eProven Compatibility from Baader to Takahashi\u003c\/h3\u003e\n\u003cp\u003eThis kit has been successfully installed on an extensive list of the most popular focusers in the astronomy market, removing the guesswork from your setup. Confirmed compatibility includes, but is not limited to, focusers from Baader (Diamond Steeltrack), Explore Scientific, MoonLite, Skywatcher (Esprit Series), and Starlight Instruments (Feathertouch). It also fits a wide range of Takahashi focusers, including the FS-60, TSA-120, and FSQ series, as well as models from Stellarvue, Vixen, and William Optics, making it one of the most adaptable motor focus solutions available.\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 v2 vs. ZWO EAF: Torque and Universal Fit\u003c\/h3\u003e\n\u003cp\u003eCompared to other popular focusers like the ZWO EAF, the Pegasus Astro Motor Focus Kit v2 distinguishes itself with superior lifting capacity and broader, more adaptable mounting hardware. While the EAF is rated for around 5 kg, the Pegasus kit's ability to lift over 6 kg provides greater peace of mind for users with heavy, high-end imaging setups. Furthermore, the Pegasus L-bracket and included couplers are designed from the ground up for universal fitment across dozens of brands, whereas other systems may require more specific, model-dependent adapters.

Askar SQA55 Autofocus Kit is an engineered hardware solution for adding precise, automated focusing to your SQA55 astrograph. This comprehensive kit includes 4 different MXL synchronous belts, 2 MXL pulleys, and 2 L-shaped hollow adapter plates to ensure compatibility with virtually any electronic focuser. With all necessary M3 and M4 screws included, you can achieve a rigid, backlash-free connection for repeatable, accurate focusing across every 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\u003eA Tensioner Pulley System for 0-Backlash Focusing\u003c\/h3\u003e\n\u003cp\u003eStandard belt-drive systems for electronic focusers often suffer from unavoidable belt slack, which introduces backlash and compromises focusing accuracy. The Askar SQA55 AF Kit solves this directly with an integrated tensioner pulley, allowing you to adjust the synchronous belt to a perfectly tight state. This eliminates slippage and ensures that every step of the focuser motor translates into precise, repeatable focus adjustments.\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 Fit: 4 Belts and 2 Pulleys for Any EAF\u003c\/h3\u003e\n\u003cp\u003eUnlike single-brand solutions, the SQA55 AF Kit is designed for near-universal compatibility. The inclusion of 4 different length MXL synchronous belts and 2 different pulleys ensures you have the right components to match the hardware of almost any electronic focuser on the market. This flexibility means you are not locked into a single ecosystem and can easily upgrade or change your focuser brand in the future without needing a new mounting kit.\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\u003eFlexible M4 Mounting for Any Imaging Train\u003c\/h3\u003e\n\u003cp\u003eMany stock adapter plates for electronic focusers are excessively long, creating mechanical interference with cameras, filter wheels, or rotators. The SQA55 AF Kit features a compact adapter bracket and 2 versatile L-shaped hollow plates secured by M4 screws. This modular design can be disassembled and reconfigured in multiple positions on the SQA55 lens tube, reserving critical space for your imaging train and preventing collisions.\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 is the advantage of the Askar SQA55 Autofocus Kit over a standard EAF adapter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Askar SQA55 AF Kit offers three key advantages. First, its \u003cstrong\u003etensioner pulley\u003c\/strong\u003e eliminates belt backlash for higher focusing accuracy. Second, its \u003cstrong\u003ecompact adapter plates\u003c\/strong\u003e are specifically designed to avoid interference with cameras and other accessories. Finally, its modular design allows the entire assembly to be installed in different positions on the SQA55, freeing up space where you need it most.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is focusing backlash and how does the Askar SQA55 AF Kit prevent it?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003e\u003cstrong\u003eBacklash\u003c\/strong\u003e is a slight lag or \"slop\" in a mechanical system, often caused by a loose drive belt. In focusing, it means the focuser doesn't move immediately or precisely when the motor turns, leading to inaccurate results. The SQA55 AF Kit prevents this by using a dedicated tensioner pulley that keeps the belt tight, ensuring there is no slack and every motor movement translates directly into focuser travel.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the Askar SQA55 Autofocus Kit with a Pegasus Astro Cube or other large EAF?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. The kit is designed for broad compatibility with focusers that may have non-standard hole spacing. The L-shaped adapter plates have a hollow design. To adjust for a wider focuser body, you can loosen the M4x12mm fixing screws, flip the plates, adjust the spacing to the correct position, and retighten the screws to lock them in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eI use a full-frame camera and filter wheel on my Askar SQA55.
