  • Adapter ESATTO 2" LP for ARCO 2"

    This adapter directly connects the PrimaLuceLab ARCO 2" rotator to the ESATTO 2" LP focuser, creating a unified imaging train with a total thickness of just 22mm. By adding only 2mm to the optical path, it maintains a generous 50.9mm clear aperture, ensuring your system remains low-profile and free of vignetting on larger sensors.

    A 22mm Combined Profile with 50.9mm Clear Aperture

    Engineered for a seamless fit, this adapter allows you to physically couple the ARCO 2" rotator and ESATTO 2" LP focuser into a single, electronically-controlled unit. This direct connection is essential for leveraging PrimaLuceLab's integrated ecosystem, allowing the ESATTO to power and control the ARCO through its dedicated port, simplifying cable management.

    The design prioritizes minimizing backfocus consumption. While the ARCO 2" rotator has a native thickness of 20mm, this adapter contributes only 2mm, resulting in a combined stack of just 22mm. Crucially, the system's large 50.9mm clear aperture is preserved, making it an ideal solution for telescopes with limited backfocus that are paired with full-frame or large-format astronomy cameras.

  • What is the primary purpose of the Adapter ESATTO 2" LP for ARCO 2"?

    Its sole purpose is to create a rigid, direct mechanical and electrical connection between a PrimaLuceLab ESATTO 2" LP robotic focuser and a PrimaLuceLab ARCO 2" rotator. This allows them to function as a single, integrated unit controlled by the PLAY software.

    How much thickness does the Adapter ESATTO 2" LP for ARCO 2" add to the imaging train?

    The adapter itself adds only 2mm of optical path length. When attached to the 20mm-thick ARCO 2" rotator, the total thickness of the rotator and adapter becomes 22mm before it threads into the ESATTO 2" LP focuser.

    Does using the Adapter ESATTO 2" LP for ARCO 2" reduce the clear aperture?

    No, it is designed to maintain the system's full 50.9mm clear aperture. This ensures there is no additional vignetting introduced when connecting the ARCO 2" rotator to the ESATTO 2" LP focuser.

    If I connect my ARCO 2" to my ESATTO 2" LP with this adapter on my Celestron EdgeHD 8", will I have issues with backfocus?

    This setup is specifically designed for telescopes with tight backfocus requirements like the EdgeHD 8". The ESATTO 2" LP (Low Profile) focuser and this minimal adapter are engineered to consume as little backfocus as possible, leaving maximum room for your off-axis guider and camera.

    Do I need this specific adapter to control the ARCO 2" from the ESATTO 2" LP?

    Yes. This adapter provides the correct threading and spacing to align the components and allow the dedicated control port on the ESATTO to power and communicate with the ARCO rotator. A standard adapter will not provide this integrated functionality.

    I'm building an imaging train for a fast refractor with a full-frame camera. Is the 50.9mm clear aperture of the ESATTO 2" LP + ARCO 2" combination sufficient?

    Yes, a 50.9mm clear aperture is excellent for a 2-inch focuser and rotator system. It is large enough to fully illuminate a full-frame sensor (43mm diagonal) without causing vignetting from the focuser or rotator itself, making it a great choice for wide-field imaging.
