  • Description

    Introducing the iOptron ZEQ25 - An extraordinary new innovation in mount design.

    The new iOptron “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—a nice benefit when setting up at a remote site. Other features include an adjustable counterweight bar to prevent obstruction with the tripod. And polar aligning is quick and accessible all the time since the polar scope is not blocked by the declination shaft.

    The ZEQ25 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 59,000 objects—its Go2Nova® Hand Controller is intuitive to use and its large 4-line LCD screen simplifies the process of setting telescopes and locating objects. The ZEQ25 – a new category of viewing and astrophotography.
