  • Player One M48M-M48M Gender Changer Adapter - 2mm

    The Player One M48M-M48M Gender Changer Adapter connects two female M48 (48mm x 0.75mm) threaded accessories while adding a minimal 2mm of optical path length. This ultra-thin adapter is essential for achieving precise back focus when your imaging train components both terminate in female M48 threads.

    Precise 2mm Spacing with M48 Male-to-Male Threads

    This adapter solves a common problem in astrophotography: connecting two accessories that both feature female M48x0.75mm threads. By providing two male M48 threads, it allows you to directly couple components like flatteners, reducers, and filter wheels. Its key feature is the minimal 2mm thickness, making it an ideal "fine-tuning" spacer for hitting critical back focus distances without introducing significant length to your imaging train.

  • What is the Player One M48M-M48M Gender Changer Adapter used for?

    The Player One M48M-M48M adapter is used to connect two pieces of equipment that both have female M48x0.75mm threads, such as joining a specific filter wheel directly to a field flattener. It serves as a male-to-male bridge and adds exactly 2mm of spacing to the optical path.

    My flattener requires 55mm of back focus, but my setup is at 53mm. Will this Player One M48 adapter work?

    Yes, this is the perfect application for this adapter. If your final component has a female M48 thread, this 2mm adapter provides the precise spacing needed to extend your current 53mm distance to the target 55mm back focus required by your flattener.

    Can I use the Player One M48 adapter to connect my telescope's M48 port to a camera with M42 T-threads?

    No, this adapter is not a thread converter. It has M48 male threads on both sides. To connect an M48 component to an M42 component, you would need a dedicated M48-to-M42 step-down adapter, not this M48M-M48M gender changer.

    What does "M48M-M48M" mean for this Player One adapter?

    The "M48M-M48M" designation indicates that the adapter has an M48 Male thread on both sides. It's a "male-to-male" gender changer, specifically designed to join two female M48 ports together.

    Is this M48 adapter the same as a 2-inch filter thread?

    Yes, the M48x0.75mm thread pitch is the standard for 2-inch astronomy filters. This adapter can be used in any optical train that utilizes this common M48 thread standard for components like filter drawers, off-axis guiders, and flatteners.

    Will adding the Player One 2mm adapter cause any vignetting?

    For its intended purpose of joining two M48 components, it should not introduce any additional vignetting, as it maintains the standard 48mm clear aperture. However, the effect of any component on vignetting depends on the entire optical train and the size of your camera's sensor.
