PrimaLuceLab Adapter ESATTO 2" for GSO/Orion/TPO Ritchey-Chretien 6 and 8"

This adapter is specifically designed to connect the ESATTO 2" robotic focuser to GSO, Orion, and TPO Ritchey-Chretien telescopes. It is compatible with both the 6-inch (152mm f/9) and 8-inch (203mm f/8) models, including both aluminum and carbon fiber tube versions.

Yes, absolutely. This adapter is the correct component to mount your ESATTO 2" focuser onto an Orion 8" Ritchey-Chretien, carbon fiber or aluminum. This setup provides the precise, repeatable focusing required to capture sharp details in the dust lanes and core of the Andromeda Galaxy (M31) during a long imaging session.

This adapter provides the core connection to the telescope tube. You will reuse the threaded extension rings that came with your GSO RC6 to set the rough focus position. Depending on your specific camera's back focus and any other accessories in your imaging train (like a filter wheel or off-axis guider), you may need additional standard extenders to precisely reach focus.

To use your telescope visually after installing the ESATTO 2" with this adapter, you will need the 2" Visual Back for ESATTO 2" (PL8410001). This accessory threads into the M56 drawtube of the ESATTO focuser and allows you to insert standard 2" diagonals and eyepieces.

Yes. The adapter provides a rigid connection between the telescope and the ESATTO 2" focuser. The ESATTO 2" itself has a 5kg (11 lb) load capacity, and this adapter ensures that connection is robust enough to handle a typical cooled astronomy camera, filter wheel, and off-axis guider without flexure.
