Product Overview
Introducing iOptron’s new compact next-generation center-balance equatorial mounts the CEM26!
Like their predecessors, the CEM26 is designed with portability in mind, weighing in at only 10 lbs it can support up to a 26lb payload an incredible 2.6 mount weight to payload ratio. The key to enable such ratios is the CEM design focuses the mount and payload weight directly on the center of the tripod rendering “natural stability”.
Building on the legacy of earlier CEM models we have added features for convenience and functionality. A positive lock gear engagement system (easy to use even when wearing gloves), Built-in Wi-Fi enabling unparallel connectivity and recordable permanent periodic error correction (PPEC) to repeat optimal PEC training sessions. Regarding functionality the CEM26 delivers precise pointing and accurate tracking. The CEM26 sets the new standard for compact equatorial mounts.
The center-balanced design mount puts the weight of the payload at the center of gravity allowing for greater natural stability. 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 CEM26 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 212,000+ 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.
The CEM26B mount has an AccuAlignTM optical polar scope installed for quick and easy polar alignment. It comes with a LiteRoc heavy duty stainless steel tripod.
