This internal version connects via USB 2.0 to a Windows 7\/8.1\/10\/11 PC, using the iPolar software to guide you to a perfect alignment in minutes, without ever needing to kneel behind the mount.\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 Precision via iPolar Software\u003c\/h3\u003e\n\u003cp\u003eThe core of the iPolar system is its ability to deliver repeatable, high-precision polar alignment essential for long-exposure astrophotography.

After connecting the iPolar to your Windows PC via USB 2.0, the software displays a live view from the camera, identifies the pole star, and shows its correct position on a digital reticle. You simply adjust the mount until the star is centered on the target—no complex reticle interpretation or uncomfortable viewing positions required.\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\u003eSeamless Internal Design for HEM15, HEM27 \u0026amp; HEM44 Mounts\u003c\/h3\u003e\n\u003cp\u003eThis version of the iPolar is engineered specifically for internal installation within iOptron's HEM15, HEM27, and HEM44 series mounts.
