  • UFC Telescope-Adapter S70a to M57a

    The Baader UFC Telescope-Adapter S70a to M57a creates a secure, low-profile connection between the Baader Universal Filter Changer (UFC) system and telescopes using the M57x0.75 thread standard. This adapter attaches to the telescope side of the UFC base, converting the S70 dovetail receiver into a male M57 thread for direct integration into your imaging train. Specifically designed for Borg telescopes, its minimal physical height ensures that critical back focus is conserved.

    Connecting the Baader UFC to M57 Threads

    This adapter is a fundamental component for integrating the modular UFC system with a wide range of focusers and optical accessories. It allows you to mount the entire UFC assembly, containing your chosen filter slider, onto any female M57x0.75 threaded port. The result is a rigid, tilt-free connection essential for high-resolution imaging.

    A Minimal-Profile Adapter for Borg OTAs

    While compatible with any M57 system, this UFC adapter is engineered with Borg telescopes in mind. These instruments often have precise back focus requirements, and this adapter's ultra-thin design consumes a negligible amount of optical path length. This makes it possible to achieve focus with complex setups that include reducers, correctors, and off-axis guiders.

    • UFC System Integration: Connects any UFC Base (telescope-side) to an M57 threaded focuser, rotator, or extension tube.
    • Borg Telescope Compatibility: Provides a direct, secure fit for Borg refractors and other telescopes that utilize the M57x0.75 thread standard.
    • Back Focus Conservation: The extremely low-profile design is critical for maintaining focus position in imaging trains where every millimeter counts.
  • What is the primary purpose of the Baader UFC S70a to M57a adapter?

    Its primary purpose is to connect the telescope-side S70 dovetail of a Baader Universal Filter Changer (UFC) base to a telescope or focuser that has a female M57x0.75 thread. It allows the UFC system to be integrated into specific imaging trains.

    How does the UFC S70a to M57a adapter help manage back focus when imaging the Andromeda Galaxy (M31) with a Borg refractor?

    When imaging large targets like the Andromeda Galaxy (M31) with a Borg refractor and a reducer, back focus is often very limited. The UFC S70a to M57a adapter has an extremely thin profile, adding almost no length to the optical path. This ensures you can fit the UFC filter changer into the imaging train and still reach focus with your camera.

    Which side of the UFC system does the S70a to M57a adapter attach to?

    This is a telescope-sided adapter. It attaches to the side of the UFC base that faces the telescope objective, converting the S70 dovetail into an M57 male thread that connects to your focuser or other upstream accessories.

    Is the UFC S70a to M57a adapter compatible with telescopes other than Borg?

    Yes. While it is specifically highlighted for Borg telescopes, this adapter will work with any telescope, focuser, or accessory that presents a female M57x0.75 thread for connection.

    If I'm using a Borg 71FL refractor, will the UFC S70a to M57a adapter allow me to connect the Baader UFC?

    Yes, provided your Borg 71FL focuser or an adapter on it terminates in a female M57x0.75 thread. This UFC adapter provides the correct male M57 thread to physically mount the UFC base onto your telescope's optical train.

    Can I use the UFC S70a to M57a adapter to attach a camera to the UFC?

    No, this is a telescope-side adapter. To attach a camera, you need a separate camera-side UFC adapter that matches your camera's specific thread or flange, such as M54 or M48.
