  • PrimaLuceLab ESATTO 3.5" LP Robotic Focuser

    The PrimaLuceLab ESATTO 3.5" LP Robotic Focuser is a low-profile solution for demanding astrographs, compatible with accessories like an M98 to M68 adapter or a 3" visual back, that integrates with the ARCO rotator and EAGLE computer for full remote control. Designed specifically for optical systems with minimal backfocus, it delivers high-precision, robotic focusing without compromising your imaging train.

    The ESATTO 3.5" LP: A Low-Profile Focuser for Astrographs

    Many astrographs and high-speed imaging systems have very little backfocus to spare, making it difficult to install a traditional motorized focuser. The ESATTO 3.5" LP solves this by providing a robust, large-aperture focusing mechanism in an exceptionally thin body, allowing you to achieve critical focus with heavy camera payloads without vignetting or mechanical flexure.

    • High Payload Capacity: Engineered to carry heavy imaging trains, including large cameras, filter wheels, and rotators, without slipping or losing focus.
    • Low-Profile Body: Its slim design preserves precious backfocus, making it possible to add a motorized focuser to optical tubes that previously could not accommodate one.
    • Large Free Aperture: The design ensures that the light cone from your telescope passes through unobstructed, preventing vignetting even with large-format sensors.

    M98 & 3" Adapters for Secure System Integration

    The ESATTO 3.5" LP features a large M98x1 female thread on the camera side, providing a secure, non-flexing connection point for your equipment. PrimaLuceLab offers a comprehensive system of optional adapters to connect virtually any camera or accessory, including a 3" visual back for eyepieces or accessories with a 3" nosepiece.

    A key feature of the adapter system is the stop ring, which allows you to rotate your camera to the perfect orientation for framing your target and then lock it down without losing coaxial alignment. This is critical for maintaining flat fields and achieving precise compositions.

    Remote Control with PLAY, ASCOM, WiFi, and USB-C

    This focuser is a fully robotic component, designed for complete remote operation. It includes a modern USB-C port for a reliable connection to an EAGLE control unit or any Windows computer, and also features built-in WiFi for wireless control from a smartphone or tablet via the ESATTO Virtual HandPad app.

    • ARCO Port: A dedicated port allows direct connection to the PrimaLuceLab ARCO rotator, creating an integrated rotating focuser that shares power and communication through a single cable, minimizing clutter.
    • PLAY Software Included: The ESATTO 3.5" LP comes with PLAY, PrimaLuceLab's own astrophotography software, for a seamless user experience.
    • ASCOM Compliant: A standard ASCOM driver ensures compatibility with third-party astrophotography software like N.I.N.A., SGP, and Maxim DL, allowing you to integrate it into your existing workflow.

  • What makes the ESATTO 3.5" LP ideal for an astrograph telescope?

    Astrographs often have very limited backfocus. The ESATTO 3.5" LP's primary advantage is its extremely low-profile design, which allows it to fit into optical trains where a thicker focuser would not. It also offers a high payload capacity and a large clear aperture, preventing flexure and vignetting with heavy, large-sensor camera setups.

    How can I control the ESATTO 3.5" LP focuser remotely?

    You have multiple options for controlling the ESATTO 3.5" LP:

    • USB-C: Connect it to an EAGLE computer or any Windows PC for control via ASCOM drivers or the included PLAY software.
    • WiFi: Use the built-in WiFi to connect to your smartphone or tablet and control focusing with the ESATTO Virtual HandPad app.
    • EAGLE Integration: When connected to an EAGLE, it becomes part of a fully integrated, remotely managed observatory system.

    Will the ESATTO 3.5" LP work with my Celestron EdgeHD 1100?

    Yes. PrimaLuceLab makes an optional adapter specifically for telescopes with the large 3.3" SC thread, such as the Celestron SCT (11" and 14") and EdgeHD (9.25", 1100, and 1400) models. This adapter allows you to securely mount the ESATTO 3.5" LP directly to your telescope's rear cell.

    What is the benefit of connecting the ARCO rotator to the ESATTO 3.5" LP?

    The ESATTO 3.5" LP features a dedicated ARCO port. This allows you to connect an ARCO rotator directly to the focuser with a single cable that provides both power and data. This creates a single, compact unit that acts as a rotating focuser, allowing you to frame your target perfectly without additional power or USB cables running to the rotator.

    What software is included with the ESATTO 3.5" LP focuser?

    The ESATTO 3.5" LP includes a license for PLAY, PrimaLuceLab's dedicated astrophotography software. It also comes with an ASCOM driver, ensuring it is compatible with most third-party astronomy software packages like N.I.N.A., Sequence Generator Pro (SGP), and others.

    How do I attach my camera to the ESATTO 3.5" LP?

    The focuser has a standard M98x1 female thread on the camera side. You will need an optional adapter to match your specific camera or accessory. PrimaLuceLab offers a wide range of adapters, such as M98 to M68, M98 to M57, and M98 to M48, many of which include a stop ring to lock the camera's rotation.

  • Optional Accessories Adapter from M98 to M68 with stop ring for ESATTO 3,5” LP; 3" visual back for ESATTO 3,5” LP
  • PrimaLuceLab 1-Year Warranty
