  • PrimaLuceLab Adapter ESATTO 2" for Sky-Watcher/Orion ED80, ED100 and ED120

    This adapter provides the critical mechanical link to upgrade your Sky-Watcher or Orion ED80, ED100, or ED120 refractor with the PrimaLuceLab ESATTO 2" robotic focuser, engineered to replace the stock focuser for a solid, precise astrophotography connection.

    Enabling Precision Autofocus on Sky-Watcher ED Apochromats

    The legendary Sky-Watcher ED doublet refractors are excellent optical platforms for astrophotography, but achieving critical focus is paramount. This adapter allows you to replace the standard focuser with the ESATTO 2" robotic focuser, unlocking the ability to perform automated, repeatable, and thermally-compensated focusing routines for perfectly sharp stars, image after image.

    Engineered for a Seamless Mechanical Fit

    This component is machined specifically to match the tube assembly of the Sky-Watcher and Orion ED80, ED100, and ED120 refractors. The adapter ensures the ESATTO 2" focuser bolts on securely, maintaining collimation and mechanical alignment of your imaging train.

    • Maintains Optical Path Length: The adapter is designed so the ESATTO 2" focuser combination matches the thickness of the original stock focuser, simplifying the process of reaching focus.
    • Imaging Train Consideration: Depending on your specific camera and accessories (like filter wheels or off-axis guiders), you may need to add optional extension tubes to achieve the correct back focus.

  • What is the purpose of this PrimaLuceLab Adapter for ESATTO 2"?

    This adapter is a required mechanical interface that allows you to remove the stock focuser from a Sky-Watcher or Orion ED80, ED100, or ED120 refractor and securely install a PrimaLuceLab ESATTO 2" robotic focuser in its place. It is essential for upgrading these specific telescopes to a high-precision, automated focusing system for astrophotography.

    Will I need other parts to use my camera with the ESATTO 2" and this adapter on my Orion ED100?

    Possibly. While this adapter ensures the focuser fits the telescope tube, the final focus position depends on your entire imaging train. Based on your camera's sensor depth, and any accessories like filter wheels or off-axis guiders, you may need to add M56 or M68 extension tubes to push the camera out to the focal plane.

    Is this adapter necessary to mount an ESATTO 2" on my Sky-Watcher ED80?

    Yes, absolutely. The ESATTO 2" focuser's native mounting flange is not directly compatible with the optical tube of the Sky-Watcher ED80, ED100, or ED120. This adapter provides the correct bolt pattern and mechanical interface for a secure, stable connection.

    How does this adapter help with astrophotography on my ED120 while imaging the Andromeda Galaxy (M31)?

    By enabling the use of an ESATTO 2" focuser on your ED120, this adapter is the first step to perfect focus on demanding targets like M31. It allows your control software (like PrimaLuceLab's PLAY) to run autofocus routines, compensating for temperature drops during the night that would otherwise cause your stars to bloat and lose detail in the galaxy's faint dust lanes.

    Does this adapter work with any focuser other than the PrimaLuceLab ESATTO 2"?

    No. This adapter is specifically designed and threaded for the PrimaLuceLab ESATTO 2" robotic focuser only. It will not work with focusers from other manufacturers.

    Is the installation of this adapter on my Sky-Watcher ED100 reversible?

    Yes. The adapter uses the existing mounting points on the telescope tube. No permanent modification to your telescope is required. You can remove the adapter and the ESATTO focuser and reinstall the original stock focuser at any time.
