The connection enables the ARCO rotator to be controlled directly through the dedicated port on the ESATTO, eliminating the need for separate power and data cables running to your control computer or hub. This integration simplifies your setup and allows for synchronized control of both focusing and field rotation from within the PrimaLuceLab PLAY astrophotography suite or other ASCOM-compatible software.\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\u003eMaintain a Rigid, High-Aperture Optical Path\u003c\/h3\u003e\n\u003cp\u003eFor observatory-class instruments and heavy imaging payloads, mechanical rigidity is critical to prevent flexure.
