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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eIntegrated Focus and Rotation: A Single-Cable Solution\u003c\/h3\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe ESATTO 3,5\" LP: Robotic Low-Profile Focusing\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eARCO 3\" Rotator: Precision Framing and De-Rotation\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eUnified Control with PLAY and ASCOM\u003c\/h3\u003e\n\u003cp\u003eYou 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow do the ESATTO 3,5\" LP and ARCO 3\" connect to my computer?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe system is designed for minimal cabling.

A short, included link cable then connects the ESATTO to the \u003cstrong\u003eARCO 3\" rotator\u003c\/strong\u003e, providing both power and data.

Second, when used with an alt-azimuth mount, it acts as a \u003cstrong\u003efield de-rotator\u003c\/strong\u003e, correcting for the apparent rotation of the sky during long exposures to keep stars pinpoint.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs this ESATTO 3,5\" LP and ARCO 3\" bundle suitable for a remote observatory?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eAbsolutely.

The \u003cstrong\u003eARCO 3\" rotator\u003c\/strong\u003e, 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIf I'm framing the Veil Nebula (NGC 6960) with my SCT, how does the ESATTO and ARCO 3\" bundle make it easier?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Veil Nebula is a large, elongated target.
