Introducing iOptron iPolar- a high precision, easy to use electronics polar scope (e-PS). What makes iPolar unique? Can be easily installed inside the RA shaft on all iOptron equatorial mounts (except SmartEQ Pro). Can be used on any mounts with adapters either internally or externally. USB plug and play (no driver needed) Works globally, no need to set northern and southern hemispheres. No visible Polaris (north) or Sigma Octantis (south) is necessary. No need to rotate the mount during polar align. iPolar is a smart electronic polar scope for everyone. Features Fast and easy to use High precision (30 arcsec) No need to see the Pole Star No need to rotate the mount during alignment Unique imaging enhancement technique Smart plate solving On screen instruction during alignment Capable under poor sky visibility condition Compatible to most equatorial mount with a proper adapter Currently Supported Mounts: Please select the correct mount from pull-down manual when ordering.
