It supports a 5kg imaging payload through a generous 50.9mm clear aperture, all while weighing only 730g. With 10mm of precise travel and a resolution of 0.03 microns per step, you can achieve critical focus remotely for sharp, high-resolution images.\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\u003eUltra-Slim 32mm Profile for Back-Focus Critical Telescopes\u003c\/h3\u003e\n\u003cp\u003eMany modern telescopes, particularly Schmidt-Cassegrains with reducers like the Celestron EdgeHD 8\", have very little back-focus to accommodate a full imaging train. The ESATTO 2\" LP directly solves this problem with its minimal 32mm optical thickness, allowing you to fit a filter wheel and off-axis guider where a standard focuser would be too long. Despite its slim design, the focuser provides a large 50.9mm clear aperture, ensuring no vignetting even with full-frame 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\u003e0.03 Micron Resolution with WiFi and USB-C Control\u003c\/h3\u003e\n\u003cp\u003eAchieving perfect focus on a high-resolution sensor requires incredibly fine adjustments. The ESATTO 2\" LP's motor provides a repeatable step resolution of just 0.03 microns, eliminating backlash and ensuring you can dial in the sharpest possible stars. You control the focuser remotely via a modern USB-C port or built-in WiFi, connecting directly to PrimaLuceLab's PLAY astrophotography software or standard ASCOM-compliant applications. The short 10mm travel range is a direct trade-off for the compact design, optimized for fine-tuning rather than coarse adjustment.\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\u003e5kg Payload Capacity and ARCO Rotator Compatibility\u003c\/h3\u003e\n\u003cp\u003eEngineered to prevent tilt and flexure, the ESATTO 2\" LP supports a robust 5kg imaging payload. This is more than enough capacity to handle a cooled astronomy camera, a filter wheel, and an off-axis guider without compromising mechanical stability. For a fully automated imaging rig, the focuser integrates seamlessly with the PrimaLuceLab ARCO robotic rotator, creating a rigid, remotely controlled system for both focusing and field framing.\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 makes the ESATTO 2\" LP essential for a Celestron EdgeHD 8\" telescope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Celestron EdgeHD 8\", especially with its 0.7x reducer, has a very strict back-focus requirement.
