Product information

The successor to the CEM25 - The New 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 using special select R.A. gears manufactured with tighter tolerances.
It also features improved larger gear switches on both axes’ making access and adjustment easier especially with light gloves on.
The Center-balanced Equatorial Mount design is whisper-quiet and light weight! The 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 and the use of two bearings to improve tracking accuracy. Given its payload capacity, this means the "Z" designed mount is unusually light. A great benefit when setting up at a remote site. Other features include an adjustable counterweight bar to prevent obstruction with the tripod. What's more, 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 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.

Do not be concerned if the box appears to have been opened. All mounts are removed from their boxes, and checked. We then apply a unique one-off, anti-tamper serial number to every product supported under our warranty. An image of the serial number is shown below. Legitimate iOptron products purchased from Offical EU Distributor Altair Astro UK and our official European partners all have this unique serial number either on the mount as shown, or inside the battery compartment. This entitles you to two years of warranty support from date of purchase, provided you can produce the original sales invoice with that serial number on it and the serial number on the product isn't showing signs of tampering.
