  • Baader Conversion Ring - M68x1(M)/M68x1(M)

    The Baader M68x1(M)/M68x1(M) Conversion Ring is a specialized male-to-male adapter that solves a critical connection problem in modular imaging trains. This ring converts any component with a female M68x1 internal thread (M68i) into a male M68x1 external thread (M68e), enabling rigid, direct-threaded connections where they would otherwise be impossible.

    Convert Female M68 Ports with a 1mm Pitch Adapter

    This adapter's primary role is to function as a thread gender changer for the M68 system. If you need to connect two components that both terminate in female M68x1 threads—such as certain focusers, off-axis guiders, or filter wheels—this conversion ring bridges the gap by creating a secure male-to-male threaded link.

    By using a direct-threaded connection, you maintain perfect optical alignment and rigidity, eliminating the potential for tilt or flex that can occur with slip-fit adapters. The M68 format itself is designed for large-format sensors, and this ring ensures the full, wide clear aperture is preserved, preventing vignetting on your imaging sensor.

  • What is the primary function of the Baader M68x1(M)/M68x1(M) Conversion Ring?

    Its main purpose is to act as a "gender changer" for threads. It takes a component that has a female M68 internal thread and converts that port into a male M68 external thread, allowing you to connect another component that also has a female M68 port.

    When would I need to convert an M68 female thread to a male thread in my imaging train?

    A common scenario is when connecting two major components that were not originally designed to mate directly. For example, you might have a high-end focuser and an off-axis guider that both have female M68 threads for connection. This ring allows you to join them securely without needing a custom adapter.

    Is the thread pitch on this Baader M68 Conversion Ring standard?

    Yes. The "x1" in M68x1 designates a thread pitch of 1mm. This is the standard pitch used across the Baader Planetarium M68 system and is compatible with M68x1 accessories from other manufacturers.

    Can I use this Baader M68 ring to connect a Baader M68 Off-Axis Guider to a focuser that also has a female M68 port?

    Absolutely. This is a perfect use case for the Baader M68 Conversion Ring. It provides a solid, threaded connection between the two components, ensuring no flexure or misalignment affects your guiding or primary imaging camera.

    Does this Baader M68 Conversion Ring add significant length to the optical path?

    While any adapter adds some length, this conversion ring is designed to be as thin as possible to minimize its impact on back focus. Its purpose is to enable a connection, not to function as an extension tube. For critical back focus calculations, you should always measure your assembled imaging train.

    Why should I use a threaded Baader M68 connection instead of a 2" nosepiece?

    A threaded M68 connection offers superior stability and alignment compared to a 2" nosepiece held by thumbscrews. For heavy imaging payloads with large cameras and filter wheels, a fully threaded train prevents tilt and sag, which is critical for achieving sharp stars across a large, flat field.
