An extraordinary innovation in mount design... Now with a new payload!




This past year we introduced a new design concept -- the center-balanced equatorial mount (or CEM) called the ZEQ25. Now, we're proud to introduce the CEM60! -- with an increased payload of 60 lbs! The CEM60 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--a nice benefit when setting up at a remote site. Other features include an adjustable counterweight bar to prevent obstruction with the tripod or pier. And polar aligning is quick and accessible all the time since the polar scope is not blocked by the declination shaft.

The CEM60 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. The Go2Nova® Hand Controller is intuitive to use and its large 8-line LCD screen simplifies the process of setting telescopes and locating objects. The CEM60- a new category (and payload capacity) of for viewing and astrophotography.
