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.
