  • Adapter ESATTO 2" LP and ARCO 2" for telescopes with SC thread

    This PrimaLuceLab adapter creates the essential mechanical link to connect the ESATTO 2" LP low-profile robotic focuser and the ARCO 2" rotator directly to the rear cell of any telescope with a standard Schmidt-Cassegrain (SC) thread. It facilitates a secure, rigid, all-threaded connection for your imaging train, eliminating potential flexure when using heavy cameras or other accessories on popular catadioptric telescopes.

    Integrate PrimaLuceLab Focusers and Rotators with SC Telescopes

    By threading directly onto your telescope's rear cell, this adapter provides a solid foundation for the ESATTO 2" LP focuser and ARCO 2" rotator. This direct-fit design ensures perfect optical alignment and mechanical rigidity, which is critical for maintaining sharp, consistent focus during long imaging sessions.

    • Direct SC Thread Connection: Provides a secure, non-slip attachment to the rear cell of Schmidt-Cassegrain, EdgeHD, and ACF telescopes, replacing less stable compression rings or nosepiece solutions.
    • Designed for ESATTO 2" LP & ARCO 2": Precisely machined to match the mounting pattern of PrimaLuceLab's low-profile focuser and rotator for a seamless, integrated fit.
    • Enables Robotic Imaging: Serves as the key component for building a fully remote-controlled focusing and field rotation system on your SC-threaded telescope.

  • What is the purpose of the PrimaLuceLab Adapter for ESATTO 2" LP and SC threads?

    This adapter allows you to securely attach PrimaLuceLab's ESATTO 2" LP robotic focuser and/or the ARCO 2" robotic rotator to any telescope that uses the standard Schmidt-Cassegrain (SC) rear cell thread. It creates a solid, all-threaded connection for astrophotography.

    Which telescopes is this PrimaLuceLab adapter compatible with?

    It is compatible with any telescope featuring a standard 2-inch SC-type male thread on its rear cell. This includes most Schmidt-Cassegrain (SCT), EdgeHD, and Advanced Coma-Free (ACF) telescopes from manufacturers like Celestron and Meade.

    Can I use this adapter to connect only the ESATTO 2" LP focuser to my Celestron EdgeHD 8?

    Yes. The adapter is designed to connect the ESATTO 2" LP focuser directly to your Celestron EdgeHD 8's SC thread. You can use it with the focuser alone or with both the focuser and the ARCO 2" rotator stacked together.

    Why is this threaded PrimaLuceLab adapter better than a 2-inch nosepiece for connecting the ESATTO to my Meade ACF?

    A threaded connection is significantly more rigid and secure than a slip-fit 2-inch nosepiece held by thumbscrews. For astrophotography, especially with heavier cameras, this adapter prevents any possibility of tilt or flexure in the imaging train, ensuring your optical components remain perfectly aligned with your Meade ACF's light path.

    Does this adapter work with the standard ESATTO 2" or only the ESATTO 2" LP model?

    This specific adapter is designed exclusively for the ESATTO 2" LP (Low Profile) focuser and the ARCO 2" rotator. It will not fit the standard, larger ESATTO 2" or other ESATTO models due to differences in the mechanical interface.

    Do I need this adapter if I'm attaching my PrimaLuceLab ESATTO 2" LP to a refractor?

    No, you typically would not use this adapter with a refractor. Refractors usually require different adapters, such as those for M68, M63, or M56 threads. This adapter is specifically for converting the ESATTO 2" LP's native connection to the SC thread found on catadioptric telescopes.
