By adding only 2mm to the optical path, it maintains a generous 50.9mm clear aperture, ensuring your system remains low-profile and free of vignetting on larger sensors.\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\u003eA 22mm Combined Profile with 50.9mm Clear Aperture\u003c\/h3\u003e\n\u003cp\u003eEngineered for a seamless fit, this adapter allows you to physically couple the ARCO 2\" rotator and ESATTO 2\" LP focuser into a single, electronically-controlled unit.

While the ARCO 2\" rotator has a native thickness of 20mm, this adapter contributes only 2mm, resulting in a combined stack of just 22mm. Crucially, the system's large 50.9mm clear aperture is preserved, making it an ideal solution for telescopes with limited backfocus that are paired with full-frame or large-format astronomy cameras.\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\"\u003eWhat is the primary purpose of the Adapter ESATTO 2\" LP for ARCO 2\"?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eIts sole purpose is to create a rigid, direct mechanical and electrical connection between a PrimaLuceLab \u003cstrong\u003eESATTO 2\" LP robotic focuser\u003c\/strong\u003e and a PrimaLuceLab \u003cstrong\u003eARCO 2\" rotator\u003c\/strong\u003e.
