  • EvoGuide 50 Clamshell Ring and Mounting Bracket for ZWO EAF

    This EvoGuide 50 Clamshell Ring and Mounting Bracket transforms your guidescope into a fully automated, compact imaging platform by seamlessly integrating a ZWO EAF motor. The kit includes two distinct motor pulleys with 4mm and 5mm bores to ensure compatibility with both new and old EAF versions. With two included 1/4-20 screws for secure dovetail mounting, the entire assembly creates a rigid, grab-and-go solution for wide-field astrophotography.

    A Unified Platform for the EvoGuide 50 & ZWO EAF

    Designed specifically for the Sky-Watcher EvoGuide 50, this system provides a robust, all-in-one mounting solution. The 3D-printed PETG clamshell ring securely holds the optical tube, while the adjoining bracket provides dedicated placement for a ZWO EAF motor and other essential accessories, such as a ZWO ASIAIR or a mini guide camera. This integration eliminates flexure and clutter, resulting in a clean, stable, and highly portable imaging rig.

    Automating the EvoGuide 50's Helical Focuser

    This kit enables precise, repeatable autofocus on the EvoGuide 50's manual helical focuser. A custom-designed pulley attaches to the focuser's green ring using non-marring nylon set screws, preserving your equipment's finish. The included timing belt connects this pulley to the ZWO EAF motor, translating the motor's fine movements into exact focus adjustments for perfectly sharp stars in every sub-exposure.

    Integrated Mounting for Accessories and Dovetails

    The clamshell ring is engineered for broad compatibility, featuring brass threaded inserts that work with the stock green dovetail supplied with the EvoGuide 50, as well as dovetail clamps from Losmandy and ADM. The bracket also incorporates a finderscope-style foot, allowing you to mount additional accessories with ease. All necessary hardware is included, from the two 1/4-20 dovetail mounting screws to the four thumbscrews for securing your gear.

  • What else do I need to use the EvoGuide 50 Clamshell Ring and Bracket?

    This is a mounting kit. To create a full imaging setup, you will need to provide your own Sky-Watcher EvoGuide 50 OTA, a ZWO EAF motor, an imaging camera, and a tracking mount. For optimal results, a field flattener like the Starizona EvoFF is also recommended.

    Will this bracket work with my ZWO EAF?

    Yes, it is designed for compatibility with ZWO EAF motors. The kit includes two different motor pulleys: one with a 4mm bore and one with a 5mm bore. This ensures it will fit the motor shaft on both older and newer versions of the ZWO EAF.

    How does the EvoGuide 50 bracket attach to the focuser without damaging it?

    The 3D-printed pulley that fits over the helical focuser's ring uses non-marring nylon set screws. Unlike metal screws, these will not scratch or dent the finish on your EvoGuide 50, ensuring a secure grip without cosmetic damage.

    What material is the EvoGuide 50 Clamshell Ring made from?

    All printed parts, including the clamshell ring and accessory bracket, are made from durable PETG filament. This material is known for its strength, temperature resistance, and rigidity, making it an excellent choice for astronomical accessories.

    How do I mount the EvoGuide 50 Clamshell Ring to my Losmandy-style dovetail bar?

    The clamshell ring features brass threaded inserts compatible with standard 1/4-20 screws. You can attach it directly to a Losmandy or Vixen-style dovetail clamp. The kit is confirmed to be compatible with clamps from both Losmandy and ADM, providing a secure connection to your primary mounting plate.

    Can I use this bracket to create a portable setup for imaging large targets like the North American Nebula (NGC 7000)?

    Absolutely. Combining the EvoGuide 50, this EAF bracket, a field flattener, and a modern CMOS camera creates an ideal wide-field imaging system. The automation provided by the EAF makes it perfect for capturing large, faint targets like the North American Nebula (NGC 7000) or the Andromeda Galaxy (M31) from a portable star tracker or equatorial mount.
