  • PrimaLuceLab Adapter ESATTO 3" for GSO/Orion/TPO Ritchey-Chretien 10, 12, 14 and 16"

    This PrimaLuceLab adapter creates the essential mechanical link for attaching the high-precision ESATTO 3" robotic focuser to large-aperture GSO, Orion, or TPO Ritchey-Chretien telescopes—including 10", 12", 14", and 16" models—providing a rigid, secure connection for automated astrophotography.

    A Secure Threaded Connection for 10" to 16" RC Telescopes

    Designed specifically for the rear cell thread of GSO, Orion, and TPO Ritchey-Chretien telescopes from 10" to 16" in aperture, this adapter ensures a solid, flex-free connection for the ESATTO 3" focuser. This rigidity is critical when supporting heavy imaging trains that include large cameras, filter wheels, and off-axis guiders.

    By replacing the telescope's stock focuser with this dedicated adapter and the ESATTO 3", you establish a professional-grade imaging platform. The direct threaded attachment eliminates the potential for tilt or sag that can occur with generic adapters or compression fittings.

    Integrating the ESATTO 3" into Your RC Optical Train

    Installing the ESATTO 3" focuser with this adapter is the first step in optimizing your RC telescope for imaging. To achieve the correct focal plane position, you will utilize the original extension rings that were supplied with your Ritchey-Chretien telescope, placing them between the rear cell and this adapter.

    Depending on your specific camera and accessories, you may need additional M81 extension tubes or other adapters on the camera-side of the ESATTO 3" to precisely reach focus. This adapter correctly positions the focuser, allowing you to build out the rest of your imaging train to meet your back focus requirements.

  • Which telescopes is the PrimaLuceLab ESATTO 3" adapter compatible with?

    This adapter is specifically designed to connect the ESATTO 3" focuser to GSO, Orion, and TPO Ritchey-Chretien telescopes with 10", 12", 14", and 16" apertures, for both aluminum and carbon fiber tube versions.

    Why do I need this specific adapter for my GSO 12" RC and ESATTO 3" focuser?

    Your GSO 12" RC has a specific thread size on its rear cell. This adapter is machined with the corresponding thread to provide a direct, secure, and perfectly aligned connection for the ESATTO 3" focuser, preventing tilt and flex that would compromise your images.

    Will I need other parts to connect my camera after installing the ESATTO 3" with this adapter?

    Yes. This adapter connects the focuser to the telescope. You will still need the appropriate camera-side adapters (e.g., M81 to M48) to connect your specific camera to the ESATTO 3" drawtube. You may also need extension tubes to achieve the correct back focus.

    Can I use this PrimaLuceLab adapter with the smaller ESATTO 2" focuser?

    No, this adapter is engineered exclusively for the bolt pattern and body of the larger ESATTO 3" focuser. A different adapter is required for the ESATTO 2".

    How does this adapter affect the back focus of my 16" TPO Ritchey-Chretien?

    The adapter itself has a specific optical thickness that contributes to the overall back focus of your imaging train. You will need to use the extension rings that came with your telescope to position the ESATTO 3" focuser correctly, and then add or remove camera-side spacers to place your sensor at the focal plane.

    Is this PrimaLuceLab adapter suitable for visual use with my Orion 10" RC?

    Yes, indirectly. The adapter's primary purpose is to mount the ESATTO 3" focuser for imaging. Once the focuser is installed, you can attach a 2" visual back to the ESATTO's drawtube, allowing you to use 2" eyepieces and accessories for high-precision visual observing.
