About this product

Model:  iop_cem25p_7100p
Part Number:  7100P

Ultra portable mount with a low periodic error of +/- 10 arc seconds!

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 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.
