  • Adapter 6x7 Flange to M68i – for TEC/AP Field Flattener

    This Baader Planetarium adapter creates the critical link between the large-format 6x7 flange found on premium Astro-Physics and TEC field flatteners and the versatile M68i thread system. It allows imagers to build a robust, fully threaded optical train that eliminates the potential for flexure inherent in slip-fit or compression-style connectors.

    Connect Your Astro-Physics/TEC 6x7 Flattener to the M68 System

    For owners of high-end Astro-Physics and Telescope Engineering Company (TEC) flatteners, this adapter unlocks the entire Baader M68 accessory ecosystem. By converting the proprietary 6x7 flange to a standard M68i female thread, you gain the ability to securely attach a wide range of imaging components.

    • System Versatility: Integrate essential tools like the Baader M68 Off-Axis Guider, filter changers, or camera rotators directly into your optical path.
    • Mechanical Rigidity: A fully threaded connection is paramount for modern imaging with heavy cameras and filter wheels. This adapter ensures your components are securely locked together, preventing tilt and maintaining perfect alignment through long exposures.
    • Precision Fit: Engineered specifically for the Astro-Physics and TEC 6x7 flange, this component guarantees a seamless and secure fit with your high-end flattener.

  • What is the purpose of the Baader 6x7 to M68i adapter?

    This adapter is designed to connect Astro-Physics and TEC field flatteners that use a 6x7 flange to the widely supported Baader M68 thread system. This allows you to build a secure, fully threaded imaging train with M68 accessories.

    Which flatteners are compatible with this Baader adapter?

    It is specifically designed for field flatteners from Astro-Physics and Telescope Engineering Company (TEC) that feature the 6x7 flange mount. It is not a universal adapter and should only be used with these compatible components.

    I have a TEC field flattener and want to use a Baader M68 Off-Axis Guider. Is this the right adapter?

    Yes, this adapter is made for exactly this scenario. It provides the M68i female thread needed to securely attach a Baader M68 OAG and other accessories directly to your TEC flattener's 6x7 flange.

    Will this adapter let me attach an M68 filter wheel to my Astro-Physics flattener for imaging the Andromeda Galaxy (M31)?

    Absolutely. This adapter creates the necessary M68i interface on your Astro-Physics flattener, allowing you to build a rigid, threaded train with M68 components like a filter wheel. This ensures a flexure-free setup for capturing deep-sky objects like the Andromeda Galaxy (M31).

    Does this adapter add flexure to the imaging train?

    No, its primary purpose is to prevent flexure. By creating a solid, threaded connection between your flattener and accessories, it provides a significantly more rigid link than slip-fit or compression ring adapters, which are common sources of tilt and flex.

    What accessories can I use once I install the 6x7 to M68i adapter?

    Installing this adapter opens up the entire Baader M68 accessory ecosystem. This includes, but is not limited to, off-axis guiders, filter wheels and drawers, camera rotators, and a wide variety of M68 extension tubes for achieving perfect back focus.
