  • Player One FHD-OAG MAX-2 Off-Axis Guider

    The Player One FHD-OAG MAX-2 is a direct response to user feedback, refining Player One's off-axis guider for large-sensor cooled cameras. Its redesigned focuser housing now has a maximum outer diameter of just 46mm, providing critical clearance in complex imaging trains. The large 8mm x 14mm prism gives a guide image free of vignetting on the Player One Xena-M, and the entire assembly adds a fixed 17.5mm to your optical path for straightforward back focus calculations.

    A Slimmer 46mm Focuser Housing

    The most significant update to the FHD-OAG MAX-2 is the redesigned guide port assembly. The maximum outer diameter of the 1.25" helical focuser housing has been reduced from 53mm to a much leaner 46mm. This gives more clearance in tight imaging trains and reduces the risk of mechanical interference between components. The internal geometry has also been reworked to minimize light leaks, which keeps stray light away from the guide camera, and the helical focuser now needs less rotation force, for a smoother action when making fine adjustments to your guide camera's focus.

    The 8mm x 14mm Prism

    At the core of the OAG is a large 8mm x 14mm rectangular prism that picks off light at the edge of the light path. Its shape is close to a 16:9 format and gives a result free of vignetting on the Player One Xena-M guide camera. Because the prism is only 8mm tall, it can sit closer to the center of the light path and accept more light.

    17.5mm Optical Length and Flexible Thread Adapters

    Integrating an OAG requires precise back focus management, and the FHD-OAG MAX-2 contributes a fixed 17.5mm of optical length. This makes it easy to factor into your calculations. The unit includes two interchangeable front pieces for connecting to your telescope: an M48x0.75 front piece comes pre-installed, and an M54x0.75 front piece is included in the box. For telescopes with M42 T-threads, a 0mm M48-to-M42 adapter is also supplied.

    • Telescope Side: Connects via M48 (installed), M54 (included), or M42 (with included adapter). An optional M68x1 front piece is sold separately for larger focusers.
    • Camera Side: Attaches directly to Player One accessories like the Filter Drawer MAX or Phoenix filter wheels using a secure 6 x M2.5 screw pattern.

    Designed for Player One Large-Format Cameras

    The FHD-OAG MAX-2 is engineered as a core component of the Player One imaging ecosystem. It is designed for Player One's large-format cooled cameras, including the Poseidon, Zeus, and Artemis series. It connects seamlessly with compatible Player One filter wheels—the Phoenix 7x36mm, 5x2", and 7x2" models—as well as the Filter Drawer MAX, creating a rigid and reliable imaging train for serious deep-sky astrophotography.

  • What's the difference between the Player One FHD-OAG MAX-2 and the original version?

    The MAX-2 is an updated version with three key improvements based on user feedback. First, the focuser housing's maximum diameter was reduced from 53mm to 46mm for better clearance. Second, the internal structure was redesigned to minimize stray light. Third, the helical focuser action was made smoother for easier adjustments.

    Which Player One cameras and filter wheels work with the FHD-OAG MAX-2?

    The FHD-OAG MAX-2 is designed for Player One's large-sensor cooled cameras, including the Poseidon series, Zeus series, and Artemis series. It connects directly to the Player One Filter Drawer MAX and the Phoenix 7x36mm, 5x2", and 7x2" filter wheels via a 6-bolt pattern.

    How much back focus does the Player One FHD-OAG MAX-2 use?

    The FHD-OAG MAX-2 adds exactly 17.5mm of optical length to your imaging train. This fixed distance must be accounted for when calculating your total back focus spacing from the flattener or corrector to the camera sensor.

    What is the best guide camera for the FHD-OAG MAX-2?

    The Player One Xena-M. Player One states that the OAG's 8mm x 14mm prism gives a result free of vignetting on the Xena-M's sensor.

    How do I connect the FHD-OAG MAX-2 to my telescope with an M42 T-thread?

    The package includes a dedicated M48M-M42F 0mm adapter. Simply thread this adapter onto the pre-installed M48 front piece of the OAG, and you can then connect the entire assembly to any standard M42x0.75 T-thread on your focuser or flattener.

    Can I use the Player One FHD-OAG MAX-2 with an M68 focuser?

    Yes, but it requires an additional accessory. Player One sells an optional M68x1 front piece (sold separately) that replaces the included M48 or M54 pieces, allowing for a direct, native connection to large M68 threaded focusers.
