A center-balanced equatorial mount, lightweight and whisper quiet


This CEM25 mount uses up to 60% less GOTO power consumption than other mounts in category.

The "Z" design mount puts the weight of the payload at the center of gravity allowing for greater natural stability. Given its payload capacity, this means the "Z" designed mount is unusually light making it very portable. A nice benefit when setting up at a remote site. Other features include an adjustable counterweight bar to prevent obstruction with the tripod. For polar alighment in the Southern Hemisphere we recommend adding the the iPolar Electroninc Polar Scope. The mount does not include a polar scope. It comes in a aluminimum hard case with an NZ compliant power supply.

The CEM25 is equipped with the latest advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. Its database includes over 59,000 objects. The Go2Nova® Hand Controller is intuitive to use and its large 4-line LCD screen simplifies the process of setting telescopes and locating objects.
