  • PrimaLuceLab ARCO 2" Robotic Rotator

    The PrimaLuceLab ARCO 2" Robotic Rotator is engineered to deliver precise, automated camera rotation and field de-rotation for advanced astrophotography. Designed for seamless integration, it allows you to frame targets perfectly without touching the telescope and enables long-exposure imaging with alt-azimuth mounts. ARCO draws all power and data through a single cable connected to your ESATTO focuser or SESTO SENSO 2/3 motor, eliminating cable clutter while providing control from your EAGLE, a Windows PC, or a mobile device via WiFi.

    Arc-Second Precision and Field De-Rotation

    ARCO's primary function is to provide incredibly fine control over your camera's orientation. With a resolution of one arcsecond per step, it allows for meticulous framing of celestial objects. For imagers using an equatorial mount, this means you can adjust your camera's angle remotely to compose the perfect shot. For those with an alt-azimuth mount, ARCO acts as a field de-rotator, actively counteracting field rotation to enable long-exposure deep-sky astrophotography—a capability previously difficult to achieve without an equatorial wedge.

    Single-Cable Connection to ESATTO and SESTO SENSO

    The ARCO 2" rotator is not a standalone device; it is a dedicated component of the PrimaLuceLab ecosystem. It connects directly to the special port on any ESATTO robotic focuser or a SESTO SENSO 2/3 focusing motor using the included cable. This single connection provides both power and data, creating a clean, integrated system without the need for separate 12V power inputs or extra USB cables running from the rotator.

    • ESATTO Integration: Connects to ESATTO 2", 3", or 4" focusers using the appropriate optional adapter (PL3600412, PL3600416, or PL3600423).
    • SESTO SENSO 2/3 Integration: Attaches to your existing focuser using an optional 2" nosepiece (PL3600413) or M48 adapter (PL3600424) and is controlled via the connected SESTO SENSO unit.

    Operation via PLAY, EAGLE, and ASCOM

    Control over the ARCO rotator is centralized through PrimaLuceLab's software suite. The included PLAY astrophotography software provides a simple interface to manage camera rotation alongside focusing with ESATTO or SESTO SENSO. When used with an EAGLE computer, PLAY unlocks more advanced features automatically. As it is ASCOM-compliant, you can also integrate ARCO into third-party sequencing software on any Windows computer, giving you the flexibility to use it with your preferred imaging workflow.

    Low-Profile, Zero-Snag Chassis

    Engineered with a focus on minimizing backfocus and preventing cable snags, the ARCO 2" rotator features a slim, self-contained chassis. All mechanical and electronic components are housed within the full aluminum body, leaving no protruding parts that could interfere with your camera, filter wheel, or the telescope itself. This thoughtful design ensures reliable operation and a secure fit within your imaging train.

  • Can I use the PrimaLuceLab ARCO 2" rotator by itself?

    No, the ARCO 2" is not a standalone unit. It is designed to be an integrated part of the PrimaLuceLab ecosystem and requires either an ESATTO robotic focuser or a SESTO SENSO 2/3 robotic focusing motor for power and control. It connects via a special port on those devices.

    How does the ARCO 2" rotator help with my alt-azimuth mount like a Celestron CPC Deluxe?

    Alt-azimuth mounts cause the field of view to rotate during long exposures, resulting in trailed stars. The ARCO 2", when used with compatible software, functions as a field de-rotator. It precisely counter-rotates your camera at the correct rate to keep stars pinpoint, allowing you to capture deep-sky objects like the Orion Nebula (M42) with long exposures.

    Do I need a separate power cable for the ARCO 2" rotator?

    No. The ARCO 2" rotator draws all necessary power and receives data commands through a single cable that connects it to your ESATTO or SESTO SENSO 2/3. This design simplifies cable management and reduces potential points of failure.

    What software do I use to control the ARCO 2" rotator?

    You can control the ARCO 2" rotator using PrimaLuceLab's proprietary PLAY software, which is included. It is also controllable from any Windows computer via its ASCOM driver, allowing integration with popular astrophotography software like N.I.N.A. or Sequence Generator Pro. If you use an EAGLE, control is seamlessly integrated.

    How do I connect the ARCO 2" to my ESATTO 2" focuser?

    To connect the ARCO 2" rotator to an ESATTO 2" focuser, you will need the optional Adapter ESATTO 2" for ARCO 2" (PL3600412). This adapter ensures a secure, threaded connection between the two devices, maintaining optical alignment.

    Will the ARCO 2" rotator work with my existing non-PrimaLuceLab focuser?

    Yes, provided you also have a SESTO SENSO 2 or SESTO SENSO 3 robotic focusing motor installed on that focuser. The ARCO connects to the SESTO SENSO, which in turn controls your focuser. You would typically attach the ARCO using the optional 2" nosepiece (PL3600413) or M48 adapter (PL3600424).
