Designed for internal installation on iOptron CEM26, GEM28, and SkyGuider Pro mounts, it connects to your Windows 7, 8, 8.1, or 10 PC via a Mini-USB 2.0 interface, drawing 5 VDC power directly from the connection.\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\u003e30 Arcsecond Plate-Solving Polar Alignment\u003c\/h3\u003e\n\u003cp\u003eThe iPolar uses a sensitive camera and intelligent software to plate-solve the sky, achieving an alignment precision of 30 arcseconds. Unlike optical scopes that rely on your ability to see Polaris, the iPolar identifies star patterns within its 13° field of view. This means you can get a precise alignment even if the pole is completely obscured by trees, buildings, or clouds—a task impossible for any traditional polar scope.\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\u003eInternal Design for CEM26, GEM28 \u0026amp; SkyGuider Pro\u003c\/h3\u003e\n\u003cp\u003eThis version of the iPolar is engineered to fit directly inside the Right Ascension (RA) axis of iOptron's CEM26, GEM28, and SkyGuider Pro mounts.
