Please Note: Payloads must be balanced for any EQ mount to perform at its best. Payload according to specifications is 27 lbs (12.3kg). Overloading the mount is not recommended (the larger iOptron CEM/GEM models are recommended). Video is for illustration purposes only.

The next step up of CEM25 – Low Periodic Error CEM25P!
The CEM25P has all of the features of the CEM25 and now has a guaranteed low periodic error of ~+/- 10 Arc seconds or less. The improved tracking accuracy is a product of tighter production tolerances. It also features larger gear switches on both axes, making access and adjustment easier especially with light gloves on.
The Center-balanced Equatorial Mount (CEM), a mount whisper quiet and light weight, 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, 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 CEM25 mount equipped with an iOptron’s AccuAlignTM polar scope. You can do a fast and accurate polar axis alignment with iOptron’s Quick Polar Alignment procedure.
The CEM25P 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 150,000+ 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.
GOTONOVA® computerized control system The revolutionary GOTONOVA® computerized control system is by far the most technologically advanced automated goto and tracking system available on the market today. With its large celestial object database, including all of the well-known galaxies, nebulae, star clusters-- not to mention the planets, sun and moon-- you’ll be able to enjoy star gazing with the simple push of a button. Both axis motors are built into a small single unit with optical encoders that provide accurate GOTO and tracking. The control system also allows you to slew the telescope at different drive speeds, keeping the object within the telescope's viewfinder for as long as you wish.
The most easy to understand controller on the market The GoToNova hand controller is much easier to use than other similar products. The hand controller is more intuitive with menu categories better organized. It also has a larger LCD screen with more lines of content compared with the competition. Using the easy-to-use hand controller and its large LCD screen, you can easily set up your telescope and select where you want to go.
32-Channel GPS All CEM25 telescope mounts come standard with a built-in 32-channel GPS module for fully automated operation and alignment. Simply turn on the Go2Nova® Controller and the GPS module will automatically synchronize your telescope location and time with the Go2Nova® computerized control system. View celestial objects without having to manually punch in the date, time, latitude or longitude.
