  • ESATTO 3,5" LP Focuser with ARCO 3" Rotator

    The PrimaLuceLab ESATTO 3,5" LP focuser and ARCO 3" rotator bundle provides integrated, remote control over both critical imaging axes in a single, compact unit. This package combines the low-profile ESATTO 3,5" robotic focuser with the versatile ARCO 3" rotator, simplifying cable management down to a single USB connection for both devices.

    Integrated Focus and Rotation: A Single-Cable Solution

    This bundle is engineered for seamless integration. The ESATTO focuser and ARCO rotator connect to each other with a short power and data cable, meaning you only need to run a single USB cable from your control computer to the ESATTO. This design drastically reduces cable drag and potential snags—a critical factor for reliable, automated imaging sessions.

    The ESATTO 3,5" LP: Robotic Low-Profile Focusing

    The ESATTO 3,5" LP is a robotic focuser designed for demanding astrophotography where backfocus is limited. Its low-profile body allows you to add precise, repeatable focusing to complex imaging trains that include off-axis guiders, filter wheels, and large-format cameras. The all-digital operation ensures you can achieve and maintain critical focus remotely without touching the telescope.

    ARCO 3" Rotator: Precision Framing and De-Rotation

    The ARCO 3" rotator serves two essential roles for the advanced imager. As a camera rotator, it allows you to precisely frame your target without physically loosening your camera. For users with alt-azimuth mounts, it functions as a field de-rotator, actively counteracting the field rotation that occurs during long exposures, enabling you to capture sharp, round stars.

    Unified Control with PLAY and ASCOM

    You can control the ESATTO 3,5" LP and ARCO 3" bundle through two powerful software pathways. PrimaLuceLab's PLAY software offers a native, all-in-one environment for controlling all your PLL devices. For universal compatibility, the included ASCOM drivers allow you to integrate the focuser and rotator into any Windows-based astrophotography workflow, including popular software like N.I.N.A. or Sequence Generator Pro.

  • How do the ESATTO 3,5" LP and ARCO 3" connect to my computer?

    The system is designed for minimal cabling. You connect a single USB cable from your computer to the ESATTO 3,5" LP focuser. A short, included link cable then connects the ESATTO to the ARCO 3" rotator, providing both power and data. This eliminates the need for multiple USB and power cables running to your telescope.

    Can I use the ESATTO 3,5" LP and ARCO 3" bundle with software other than PLAY?

    Yes. Both the ESATTO focuser and ARCO rotator come with ASCOM drivers. This allows you to control them using any ASCOM-compliant astrophotography software on a Windows computer, ensuring compatibility with most popular automation and capture programs.

    What is the main benefit of using the ARCO 3" rotator in this ESATTO bundle?

    The ARCO 3" rotator provides two key functions. First, it allows for precise framing of celestial objects without having to manually rotate your camera. Second, when used with an alt-azimuth mount, it acts as a field de-rotator, correcting for the apparent rotation of the sky during long exposures to keep stars pinpoint.

    Is this ESATTO 3,5" LP and ARCO 3" bundle suitable for a remote observatory?

    Absolutely. The bundle's robust, all-digital design, remote control capabilities via ASCOM or PLAY, and simplified single-cable connection make it an ideal choice for unattended, remote imaging setups where reliability and precise automation are essential.

    I use a Celestron CPC fork mount. How does the ARCO 3" rotator in this ESATTO bundle help with long exposures?

    On an alt-azimuth mount like the Celestron CPC, stars will appear to rotate around the center of the field during long exposures. The ARCO 3" rotator, when used in de-rotator mode with compatible software, will slowly turn your camera to match this rotation. This allows you to take multi-minute exposures without star trails, which would otherwise be impossible without an equatorial wedge.

    If I'm framing the Veil Nebula (NGC 6960) with my SCT, how does the ESATTO and ARCO 3" bundle make it easier?

    The Veil Nebula is a large, elongated target. The ARCO 3" rotator lets you remotely adjust the camera's orientation in fine increments to perfectly align the nebula's structure with your sensor's long axis. Once framed, the ESATTO 3,5" LP focuser allows you to achieve critical focus on the faint filaments without physically touching the telescope, preventing any shifts in your carefully set composition.
