  • PrimaLuceLab Adapter for ESATTO 2" on GSO/Orion/TPO 6" & 8" RC Telescopes

    This PrimaLuceLab adapter provides the essential mechanical link for upgrading your GSO, Orion, or TPO 6" or 8" Ritchey-Chretien telescope with the high-precision ESATTO 2" robotic focuser. It is designed specifically for the popular 152mm f/9 and 203mm f/8 RC models, ensuring a direct and secure fit to the optical tube for serious astrophotography.

    Seamless ESATTO 2" Integration for GSO, Orion & TPO RC Telescopes

    Unlock the full imaging potential of your Ritchey-Chretien by replacing the stock focuser with the PrimaLuceLab ESATTO 2". This adapter creates a solid, stable connection directly to the telescope's rear threads, providing the rigid base needed for automated focusing. You can utilize the standard extension rings that came with your telescope to correctly position the focuser for your specific imaging train.

    Note that depending on your camera and any accessories like off-axis guiders or filter wheels, you may require additional M48 or other standard extenders to achieve focus. This adapter is the critical first step in building a powerful, remotely-controlled imaging setup around your RC telescope.

    Secure, Non-Marring Connection for Your Imaging Train

    PrimaLuceLab designed this adapter to not only provide a secure fit but also to protect your valuable equipment. An internal brass compression ring ensures that when you insert a 2" nosepiece from a camera or visual back, it is held firmly without the risk of scratches from steel set screws. Three locking screws, spaced at 120°, provide a perfectly centered and stable grip on your accessories, preventing any tilt in the optical path.

  • Which telescopes is this PrimaLuceLab ESATTO 2" adapter compatible with?

    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.

    Can I use this adapter to mount the ESATTO 2" on my Orion 8" RC Carbon Fiber for imaging the Andromeda Galaxy (M31)?

    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.

    Do I need extra parts to install the ESATTO 2" on my GSO RC6 using this adapter?

    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.

    How do I use my GSO RC8 for visual observation with this adapter and an ESATTO 2" focuser?

    To use your telescope visually after installing the ESATTO 2" with this adapter, you will need the 2" Visual Back for ESATTO 2" (PL3600215). This accessory threads into the M56 drawtube of the ESATTO focuser and allows you to insert standard 2" diagonals and eyepieces.

    Will this adapter securely hold my heavy imaging camera and the ESATTO 2" focuser?

    Yes. The adapter is machined to create a rigid, all-threaded 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.

    What is the purpose of the brass compression ring on this adapter?

    The internal brass compression ring is a premium feature that protects your equipment. When you tighten the three locking screws, the soft brass ring is what makes contact with your 2" nosepiece or accessory. This prevents the steel screws from directly digging into and scratching the barrel of your expensive cameras or diagonals.
