  • PrimaLuceLab ESATTO 2" Robotic microFocuser

    The PrimaLuceLab ESATTO 2" Robotic microFocuser is an all-in-one focusing solution, integrating a powerful motor and advanced electronics directly into a compact focuser body. It provides the high-precision, repeatable focus adjustments required for modern astrophotography, supporting heavy camera payloads without introducing image shift. Control is managed directly from a Windows computer or EAGLE via a USB-C connection, or wirelessly from a smartphone or tablet using its built-in WiFi and the Virtual HandPad app.

    Robotic Micro-Focusing for Heavy Imaging Payloads

    Designed specifically for astrophotography, the ESATTO replaces stock focusers that often suffer from flexure and imprecision. Its special Crayford mechanism, supported by numerous internal ball bearings, ensures exceptionally smooth draw tube movement, allowing it to handle the weight of cooled cameras, filter wheels, and other accessories with a high payload capacity. This rigidity is critical for automated focusing routines, enabling software to achieve sharp, repeatable focus without mechanical slop or backlash.

    Integrated Control via USB-C, WiFi, and ASCOM

    The ESATTO eliminates the need for external motor controllers and cumbersome hand pads. For full-session remote control, connect it to any Windows computer or PrimaLuceLab EAGLE unit with the included USB-C cable to use the PLAY astrophotography software or the provided ASCOM driver. For visual use or quick adjustments at the telescope, the built-in WiFi allows you to connect wirelessly from any smartphone or tablet and use the Virtual HandPad app, giving you complete control without being tethered to a computer.

    Low-Profile Design with Seamless ARCO Rotator Connection

    With its compact, low-profile body, the ESATTO is an ideal upgrade for telescopes where backfocus is limited, such as Schmidt-Cassegrains and EdgeHD systems. This design minimizes the focuser's depth, leaving more room for your imaging train. The ESATTO also features a dedicated port for the ARCO robotic camera rotator, allowing the two devices to connect directly with a single cable for both power and data. This integration simplifies cable management and unifies control of both focusing and field rotation within the PrimaLuceLab ecosystem.

  • What makes the PrimaLuceLab ESATTO 2" focuser "robotic"?

    The "robotic" designation means the motor, controller, and all electronics are built directly into the focuser body. This all-in-one design eliminates the need for external control boxes or separate motors, simplifying your setup and cable management. You can control it remotely from a computer, smartphone, or tablet.

    Is the ESATTO 2" a good focuser for a Celestron EdgeHD 800 or SCT?

    Yes, it's an excellent choice. Its low-profile design is critical for SCT and EdgeHD telescopes that have limited backfocus. By using an external focuser like the ESATTO, you can achieve much finer focus adjustments and completely avoid the "mirror flop" or "image shift" common with the stock internal focusing mechanism.

    How do I connect the ARCO rotator to the ESATTO 2" microFocuser?

    The ESATTO 2" features a dedicated ARCO port specifically for this purpose. You connect the ARCO rotator directly to the ESATTO with a single, short cable. This one cable provides both power and data to the rotator, so you don't need to run additional power or USB cables from your main computer or power supply to the ARCO.

    Can I use the PrimaLuceLab ESATTO 2" for visual observing?

    Absolutely. While designed for astrophotography, the ESATTO is also great for visual use. You can connect to its built-in WiFi network with your smartphone or tablet and use the Virtual HandPad app. This lets you make fine focus adjustments electronically without touching the telescope, which is especially useful at high magnifications to prevent vibrations.

    What software is compatible with the ESATTO 2" focuser?

    The ESATTO 2" works with PrimaLuceLab's own PLAY software for an integrated experience. It also comes with an ASCOM driver, making it compatible with most third-party astrophotography software, such as N.I.N.A., Sequence Generator Pro (SGP), and others that support the ASCOM standard.

    How is the ESATTO 2" powered?

    The ESATTO 2" can be powered and controlled through its USB-C port when connected to a computer port capable of supplying sufficient current. For setups where the USB port power is insufficient, or for standalone WiFi operation, it can be powered via a standard 12V DC input (power adapter not included).
