Center-balanced Equatorial Mount, a mount whisper quiet and light weight! The mount uses up to 60% less GOTO power consumption then 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 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.

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.

What if, your equatorial mount could carry a pay load over 2.5 times its own weight.  Track celestial objects with a periodic error less than 0.3 arc seconds RMS.  GOTO slew using 60% of the power consumed by other drive systems in its category, while remaining ultra quiet during operation.  Our CEM25EC achieves all of this and more.
 
Our design engineers were presented with a challenge; build a compact, light weight, extremely accurate, stable, equatorial mount, that retails for under $2000.00 dollars.
 
We started out by applying lessons learned in the creation of our revolutionary ZEQ25 and CEM60 mounts. The "center balance" approach, shifting the pay load center of gravity directly over the tripod allowing for greater natural stability, a characteristic that would accommodate reducing the mounts weight.  Using our own power consumption reduction technology we were able to replace the ZEQ25's servo motors, with more accurate and reliable steppers , maintaining relatively low power consumption.  We knew encoders were needed to achieve a PE of less than 0.3 arc seconds RMS, at the time, most commercially available encoder solutions were priced too high to feasibly achieve a $2000.00 retail price.  So, we designed our own.  Next to make a mount capable of carrying a pay load 2.5 time its own weight.  Our team looked at every component in the assembly, ounce by ounce shaving excess "fat" while leaving "muscle" behind where needed.
 
This 10.4 pound engineering marvel with its herculean capabilities in its compact light weight package exceeds the expectations of the on the go observer.  The CEM25EC opens up the door to performance not previously attainable by those not willing or not able to transport the inefficient and heavy equatorial mounts of the past.
