The iOptron CEM70EC2W is one of the latest versions of the CEM70 equatorial mount, and this one comes with an upgraded high resolution optical encoder on both the RA and Declination drive. The CEM70EC2W includes all of the advanced features of the CEM70EC Center Balanced Mount as well as new features like USB3.0, WiFi, and as we mentioned, high res optical encoders on both axes instead of just one!
The mount is packed with advanced features, however the CEM70EC2W is the first of its type with dual axis high resolution encoders for increased tracking accuracy while streamlining the components resulting in a more portable imaging setup.
Retaining the inherent properties of the center balance design, these relatively compact medium payload mounts deliver what astronomers expect in an efficient accurate portable mount. With precise GOTO pointing and amazingly accurate tracking, the CEM70ECW is a solid performer for observers and imagers alike.
Innovative operational features such as the internal iPolar electronic polar scope, easy lock drive gear engagement (levers large enough to use with gloves), an advanced cable management system for the mount, iPolar, guider, and camera, and cumulatively assure users the CEM70EC2W designed with their needs in mind.
NOTE: This product is the mount head plus iPolar, one 20 pound Counterweight, plus a Hard Case. NOTE: NO tripod or pier is included with this Head.
