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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Slimmer 46mm Focuser Housing\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe 8mm x 14mm Prism\u003c\/h3\u003e\n\u003cp\u003eAt 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e17.5mm Optical Length and Flexible Thread Adapters\u003c\/h3\u003e\n\u003cp\u003eIntegrating 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.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTelescope Side:\u003c\/strong\u003e Connects via M48 (installed), M54 (included), or M42 (with included adapter).
