Player One FHD-OAG MAX — new OAG-MAX-2 version

Player One FHD-OAG MAX — new OAG-MAX-2 version

The FHD-OAG MAX is an optical splitter designed for autoguiding through the same instrument as the main camera. Its prism splits off a portion of the beam for the guide camera. This new version retains the 8 × 14 mm rectangular prism and the 17.5 mm extension length, while upgrading the focusing mechanism.

Improvements Compared to the Previous Version

• Narrower focus housing: 46 mm instead of 53 mm. This reduction in the maximum outer diameter applies to the housing of the guide eyepiece holder, not to the diameter of the optical path. It frees up space around the accessories and reduces the risk of mechanical collisions in tight setups.
• Better protection against light leakage. Player One has redesigned the internal geometry to limit the amount of stray light that could interfere with the guidance camera’s signal. This is an improvement announced by the manufacturer, not a guarantee of absolute light tightness.
• Smoother helical focus adjustment. The force required to rotate the device has been reduced to make it easier to adjust the focus on the guide star.

Technical specifications

Mounting and compatibility

Final compatibility depends on the connectors, the wheel or filter drawer, and the focus travel required by your corrector. The 17.5 mm refers to the OAG's extension length, not the total focus travel of the entire imaging train. Check your setup before installation.

The 8 × 14 mm prism is designed to illuminate a compatible guidance sensor. The absence of vignetting claimed by Player One applies specifically to the Xena-M camera; it is not a universal guarantee for all sensors or setups.

The photograph shows the new version of the optical splitter. The guide camera, main camera, and other accessories in the imaging system are not included.
