Its wide 13° field of view camera and dedicated software for Windows 7, 8, 8.1, and 10 PCs allow for precise alignment in minutes, even when clouds or light pollution obscure your view of the pole star.\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\u003eDigital Polar Alignment: 30 Arcsecond Precision Without Polaris\u003c\/h3\u003e\n\u003cp\u003eThe core of the iPolar is a digital camera that captures a wide 13° field of the sky, paired with intelligent software that plate-solves the star patterns. This system calculates the true celestial pole's position and guides you through alignment with on-screen instructions, achieving a precision of 30 arcseconds without you ever needing to see Polaris or Sigma Octantis directly. This makes accurate setup possible from light-polluted backyards, balconies with obstructed views, or during nights with passing clouds.\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 CEM120 Design with USB 2.0 PC Control\u003c\/h3\u003e\n\u003cp\u003eThis version of the iPolar is engineered specifically to fit inside the Right Ascension (RA) axis of the iOptron CEM120 mount. This internal mounting keeps the device protected and ensures there are no external components to snag cables or interfere with your imaging equipment. A single Mini-USB 2.0 connection to your Windows PC provides both power and data, with plug-and-play operation that requires no special driver installation to get started.\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\u003eiPolar vs. Optical Scopes: A 13° Digital View for Any Sky\u003c\/h3\u003e\n\u003cp\u003eUnlike a traditional optical polar scope, which requires you to kneel behind the mount and squint through a small eyepiece, the iPolar displays its wide 13° field of view on your computer screen. This eliminates physical discomfort and the challenge of interpreting reticle markings in the dark. The software-driven process is faster and more intuitive, removing the guesswork and delivering repeatable, high-precision alignment for demanding astrophotography sessions.\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\"\u003eHow does the iOptron iPolar for CEM120 achieve a 30 arcsecond alignment?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe iPolar uses a sensitive digital camera and software to take a picture of the sky near the pole.

This is a primary advantage of the iPolar. As long as the camera can see a portion of the sky around the celestial pole, the software can plate-solve the visible stars to find the pole's location.
