  • Baader Adapter for Baader Wide T-Ring - S52/M68

    The Baader Adapter for Baader Wide T-Ring - S52/M68 provides a robust, single-piece solution for connecting any Baader Wide T-Ring to an M68x1 threaded accessory. This expansion ring converts the native S52 dovetail thread directly to M68, creating a secure, fully threaded connection that maximizes the clear aperture for modern camera sensors.

    S52 to M68: A Secure Connection with Maximum Aperture

    For astrophotographers building an imaging train with M68 components, stepping down to smaller M48 or T2 threads introduces a bottleneck that can cause significant vignetting on full-frame and large APS-C sensors. This S52/M68 adapter eliminates that compromise by maintaining the largest possible light path from your corrector or focuser directly to your camera's Baader Wide T-Ring.

    The single-piece, all-metal construction ensures a rigid, flex-free connection. By screwing directly into your M68 accessory, it creates a more stable optical train than stacks of smaller adapters, preventing tilt that can compromise image sharpness and flat-field correction.

    • Vignetting Prevention: The wide M68 diameter maintains a large, unobstructed light cone, which is critical for evenly illuminating large camera sensors.
    • System Rigidity: A direct, threaded M68 connection eliminates a potential point of flexure compared to using smaller adapters, ensuring superior optical alignment.
    • Baader System Integration: Designed specifically to integrate Baader's Wide T-Ring system with their M68 components, ensuring correct spacing and a seamless fit.

  • What is the primary use for the Baader S52/M68 Adapter?

    The primary use of the Baader S52/M68 adapter is to connect any Baader Wide T-Ring (which uses an S52 dovetail thread) directly to a telescope focuser, off-axis guider, or field corrector that has a female M68x1 thread. It creates a wide, secure connection for imaging.

    I have a 3" focuser ending in an M68 female thread. How do I connect my full-frame DSLR using the Baader S52/M68 Adapter?

    You would thread this adapter's M68 male thread directly into your focuser. Then, you attach the appropriate Baader Wide T-Ring for your camera's bayonet mount (e.g., Canon EOS or Nikon) to the S52 side of the adapter. This provides a secure, wide-aperture connection for your DSLR.

    Why use the Baader S52/M68 adapter instead of just stepping down to M48?

    Stepping down from M68 to a smaller M48 thread creates a physical bottleneck in the light path. This can cause vignetting (darkened corners) on images taken with large sensors, such as those in full-frame DSLRs or dedicated astronomy cameras. The S52/M68 adapter maintains the maximum possible clear aperture to prevent this issue.

    Is the Baader S52/M68 adapter compatible with all Baader Wide T-Rings?

    Yes. This adapter is specifically designed to attach to any Baader Wide T-Ring that features the standard S52 dovetail attachment. It serves as the bridge between that camera-side system and the telescope-side M68 system.

    I'm building an imaging train with a Baader M68 Off-Axis Guider. Will this adapter help connect my camera?

    Yes, this adapter is a key component for that setup. If your camera is attached via a Baader Wide T-Ring, the S52/M68 adapter provides the correct interface to securely connect the T-ring to the M68 threads on the guider or other M68 accessories in your optical train.

    What are the thread types on the Baader S52/M68 Adapter?

    The adapter has two male threads:

    • Telescope Side: M68x1 Male Thread
    • Camera Side: S52 Male Dovetail Thread (for Baader Wide T-Rings)
  • Part Number S52/M68a
