  • Player One M54M-M68F Adapter - 17.5mm

    The Player One M54M-M68F Adapter provides a secure, rigid connection between accessories with M54 male threads and components requiring a female M68 thread. This adapter adds a precise 17.5mm of optical path length, essential for building an exact imaging train and achieving correct back focus.

    Bridging M54 and M68 Thread Standards

    This adapter creates a critical mechanical link between two common, but incompatible, thread sizes in astrophotography. It allows you to connect accessories with an M54 male thread, such as those on many Player One cameras and filter wheels, to focusers, rotators, or field correctors that utilize the larger M68 female thread standard.

    By providing a fixed, non-adjustable 17.5mm extension, it helps achieve the specific back focus distance required by your optical system. Its rigid, all-metal construction prevents flexure, maintaining perfect optical alignment even with heavier cameras or accessories.

  • What is the primary use for the Player One M54M-M68F Adapter?

    This adapter is designed to connect two different thread standards, allowing you to attach an accessory with M54 male threads to a telescope, rotator, or corrector that has M68 female threads. It also adds a fixed 17.5mm of length to the optical path.

    Which direction does the Player One M54M-M68F Adapter convert?

    It features an M54 male thread on one side and an M68 female thread on the other. This configuration adapts smaller M54-based components to larger M68-threaded accessories.

    Is the Player One M54M-M68F Adapter suitable for heavy imaging trains?

    Yes. It is machined from metal to provide a rigid, secure connection that minimizes flexure, making it suitable for supporting typical astrophotography camera and filter wheel combinations without compromising alignment.

    How does the Player One M54M-M68F Adapter affect back focus?

    This adapter adds a fixed 17.5mm of length to your optical path. You must include this distance in your total back focus calculation to ensure your field flattener or reducer performs correctly.

    My Player One camera has M54 threads but my new rotator uses M68. Will the M54M-M68F Adapter work?

    Yes, this is a perfect use case for this adapter. It will allow you to securely attach your M54-threaded camera to the M68-threaded rotator, creating a stable connection while adding 17.5mm to the spacing.

    How would I use the Player One M54M-M68F adapter with a large refractor's field flattener?

    Many large-format field flatteners for refractors terminate in an M68 thread to prevent vignetting. This adapter allows you to connect a camera or filter wheel with a smaller M54 thread to that flattener, forming part of a rigid, threaded imaging train.
