  • SESTO SENSO 3 Robotic Focusing Motor

    The PrimaLuceLab SESTO SENSO 3 is our most advanced robotic focusing motor, engineered to deliver exceptional precision for external focusers. It introduces an integrated position encoder that permits manual focuser adjustments without losing calibration, a Self Centering Clamp 2 (SCC2) for rapid installation without external brackets, and both USB-C and WiFi connectivity for complete control. You can operate the SESTO SENSO 3 from a computer via its ASCOM driver or PLAY software, or wirelessly from a smartphone using the Virtual HandPad.

    Integrated Encoder: Manual Focusing Without Losing Calibration

    The standout feature of the SESTO SENSO 3 is its integrated position encoder. This system precisely tracks the focuser shaft's movement, allowing you to make manual adjustments with the original focuser knob at any time without the motor losing its calibrated position. This is ideal for observers who switch between visual use and astrophotography.

    For added security, the Automatic Position Recovery function can be enabled. If the focuser is accidentally moved, this feature automatically returns it to the previous position after a user-defined delay, protecting your focus during public outreach events or unattended remote sessions.

    Flexible Control: USB-C, WiFi, and Virtual HandPad

    The SESTO SENSO 3 offers modern, reliable connectivity options for any workflow. A reversible USB-C port ensures a secure connection to any Windows computer or PrimaLuceLab EAGLE, minimizing the risk of accidental disconnection in the dark.

    For ultimate freedom, the built-in WiFi creates its own network, allowing you to connect directly with a smartphone or tablet. The browser-based Virtual HandPad gives you full control over focuser movement and presets, effectively turning your mobile device into a smart hand controller—no computer or cables required at the telescope.

    Seamless Integration: SCC2 Clamp, ARCO Port, and PLAY Software

    Installation is simplified with the new Self Centering Clamp 2 (SCC2), which attaches the SESTO SENSO 3 directly to a wide range of focusers without needing external brackets. The compact, all-in-one chassis houses all electronics and features dimmable LEDs that can be fully extinguished using DARK mode to eliminate stray light.

    • ARCO Ready: A dedicated port provides single-cable power and data for the optional ARCO robotic rotator, enabling a clean, fully integrated imaging train.
    • Broad Software Support: The included ASCOM driver ensures compatibility with popular third-party software like NINA, Sequence Generator Pro, and MaxIm DL.
    • PLAY Software: Unlock advanced features like automated focusing routines and temperature compensation (with optional probe) using PrimaLuceLab's dedicated PLAY astrophotography suite.

    SESTO SENSO 3 vs. Predecessors: What's New?

    The SESTO SENSO 3 represents a significant evolution in robotic focusing, moving beyond the capabilities of previous models. While older focus motors would lose their position if touched manually, the SESTO SENSO 3's integrated encoder solves this problem completely.

    Key upgrades include the move to a bracketless mounting system with the SCC2 clamp and the introduction of modern USB-C and WiFi control. These features create a more robust, flexible, and user-friendly system for both remote imagers and hands-on visual observers.

  • What is the main advantage of the SESTO SENSO 3's integrated encoder?

    The integrated encoder allows you to manually turn the focuser knob at any time without the SESTO SENSO 3 losing its electronic position. This is a major advantage for users who switch between visual observing and imaging, as you can make coarse adjustments by hand and then switch to fine electronic control without needing to recalibrate.

    Can I control the SESTO SENSO 3 without a computer at the telescope?

    Yes. The SESTO SENSO 3 has built-in WiFi that creates its own wireless network. You can connect to it with any smartphone or tablet and use the web-based Virtual HandPad to move the focuser, save positions, and make precise adjustments without needing a connected PC.

    How does the SESTO SENSO 3 attach to my Crayford focuser?

    The SESTO SENSO 3 uses the included Self Centering Clamp 2 (SCC2) system. This allows it to connect directly to the focuser shaft of many popular Crayford and rack-and-pinion focusers without requiring any external, custom-made brackets, which simplifies installation significantly.

    I use NINA for imaging. Is the SESTO SENSO 3 compatible?

    Absolutely. The SESTO SENSO 3 includes a dedicated ASCOM driver. This ensures full compatibility with a wide range of third-party astrophotography software, including NINA, Sequence Generator Pro (SGP), MaxIm DL, and others that support the ASCOM standard.

    My observatory has public viewing nights. How does the SESTO SENSO 3 handle accidental bumps to the focuser knob?

    This is a perfect use case for the Automatic Position Recovery feature. When enabled, if the SESTO SENSO 3 detects that the focuser has been moved manually (either intentionally or accidentally), it will automatically move the focuser back to its last commanded position, ensuring your target remains perfectly focused for the next person.

    I want to build a fully remote imaging rig with a rotator. How does the SESTO SENSO 3 fit into this system?

    The SESTO SENSO 3 is designed for this scenario. It features a dedicated ARCO port that allows you to connect a PrimaLuceLab ARCO rotator with a single cable for both power and data. This creates a clean, compact, and fully integrated system for focusing and framing that can be controlled remotely through the EAGLE or another computer running PLAY or ASCOM-compatible software.
