  • Description

    The iOptron CEM60 is an innovative type of German equatorial mount that puts the weight of the payload at the center of gravity, allowing for greater natural stability. This makes the mount extremely light compared to its payload capacity of 60 pounds—a nice benefit when setting up at a remote site. And polar aligning is quick and accessible all the time since the polar scope is not blocked by the declination shaft.

    The iOptron CEM60 Equatorial Mount is equipped with the most advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. Its database includes over 300,000 objects. Other features include an adjustable counterweight bar, magnetically loaded gear system, gear switches on both R.A. and DEC axes, screw/worm type latitude adjuster and built-in or customized cable management system.
