Product Overview
Introducing iOptron CEM70-NUC equatorial mount!
Need more versatility of an equatorial mount without cable tangling? Tired of connection error with some third party control interface? iOptron NUC-ready mounts are coming! A CEM70-NUC is ready to mate with Intel® NUC minicomputer (thickness=38mm) at the front of dovetail saddle seamlessly with the cable management system.
Retaining the inherent properties of the centre balanced design, these relatively compact medium payload mounts deliver what astronomers expect in an efficient accurate portable mount. Precise GOTO point and accurate tracking indicatd the CEM70 is a solid performer for observers and imagers alike.
Innovative features such as the internal iPolar electronic polar scope, easy lock drive gear engagement, that can be used with gloves, and advanced cable management system, iPolar, guider camera. assure users the CEM70 and 70G are designed with their needs in mind. On top of the built-in guiding system, the CEM70G also comes standard with WiFi, and USB 3.0 support. (CEM70 is USB2.0 only and optional wifi) A hard case is included with each mount.
