  • Adapter ESATTO 2” LP for telescopes with large 3.3" SC thread

    This adapter provides the essential mechanical link to connect your PrimaLuceLab ESATTO 2" LP robotic focuser to large-aperture Celestron SCT and EdgeHD telescopes. It replaces the standard visual back, creating a secure, all-threaded connection from the telescope's large 3.3-inch rear port to the ESATTO focuser, eliminating any potential for flexure or misalignment in your imaging train.

    Native Integration for Celestron 11" and 14" Telescopes

    If you own a Celestron SCT 11", SCT 14", EdgeHD 925, EdgeHD 1100, or EdgeHD 1400, the standard SCT thread is replaced by a larger, more robust 3.3" thread. This adapter is specifically machined to match that thread, allowing you to mount the ESATTO 2" LP low-profile focuser and the ARCO 2" rotator directly to the telescope's rear cell for precise, automated control.

    Preserve Critical Backfocus with EdgeHD Reducers

    The adapter features a minimal optical thickness, a critical design choice for preserving the limited backfocus available on Schmidt-Cassegrain systems. This low-profile construction ensures you have sufficient space for your camera and accessories, even when using the Celestron EdgeHD 0.7x focal reducer on the 925, 1100, and 1400 models. You can build a complete, rigid imaging train without sacrificing the reducer's performance.

  • Which Celestron telescopes is this ESATTO 2” LP adapter compatible with?

    This adapter is designed for Celestron telescopes that use the large 3.3" rear thread. This includes the Celestron SCT 11" and 14" models, as well as the EdgeHD 925, 1100, and 1400 models.

    Can I use this adapter with my Celestron EdgeHD 1100 and the .7x focal reducer?

    Yes. The adapter is specifically designed with a minimal profile to preserve as much backfocus as possible, making it fully compatible with the Celestron 0.7x focal reducers for the EdgeHD 925, 1100, and 1400 models.

    Does this ESATTO 2” LP adapter connect any other PrimaLuceLab accessories?

    Yes, this adapter creates the correct threaded connection for the ESATTO 2" LP focuser, which then allows you to attach other accessories in the PrimaLuceLab ecosystem, such as the ARCO 2" robotic rotator, for a fully automated imaging setup.

    Why do I need a special adapter for the ESATTO 2” LP on these larger SCTs?

    Unlike smaller SCTs that use a 2" thread, larger Celestron models (11" and up) feature a wider 3.3" rear port for better stability and to prevent vignetting with large sensors. This adapter securely steps down from that large 3.3" thread to the input thread of the ESATTO 2" LP focuser.

    How does this adapter affect imaging the Andromeda Galaxy (M31) with my C14 and reducer?

    The adapter's primary role is to ensure a rigid, flex-free connection for your focuser and camera. Its thin profile is crucial for maintaining the precise spacing required by the focal reducer to achieve a flat field, ensuring stars are sharp across the entire frame when capturing large targets like the Andromeda Galaxy (M31).

    Will this adapter work with the standard ESATTO 2" or ESATTO 3" focuser?

    No, this adapter is specifically designed to connect to the ESATTO 2" LP (Low Profile) robotic focuser. It is not compatible with the standard ESATTO 2" or larger models, which have different threading and body designs.
