iOptron CEM25 EC with 2" tripod and hard case

A Mount with PE Less Than 0.3 arcsec rms  - The New CEM25EC!

Centre-balanced Equatorial Mount, a mount whisper quiet and light weight! The mount uses up to 60% less GOTO power consumption than other mounts in category.

With high precision optical encoder system and advanced control technology, the CEM25EC will track a star at a periodic error less than 0.3 arc second, the only mount under $2000!

The "Z" design mount puts the weight of the payload at the centre 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 mount comes standard with 2" heavy duty stainless steel tripod and a hard carrying case.

Features
  • A new design Centre-Balanced equatorial mount for maximum payload and minimum mount weight
  • Specialized astrophotography mount ideal for entry-level and intermediate Astro-photographers
  • High precision optical encoder system and advance control technology for accurate tracking
  • PE<0.3 arc second RMS
  • Payload of 27 lbs (12.3 kg) with the mount-only weight of 10.4 lbs (4.7 kg)
  • Spring loaded gear system with customer adjustable loading force
  • Gear switches on both R.A. and DEC axes for easy balancing when disengaged
  • Adjustable counterweight shaft for 0º latitude operation
  • Stepper motor with low power consumption
  • New electronics and control adapted from CEM60
  • iOptron AccuAlignTM calibrated polar scope with dark-field illumination and easy polar alignment procedure, allowing for fast and accurate polar alignment
  • Polar alignment routine for those who can’t see the Pole Star
  • Go2Nova® 8408 controller with Advanced GOTONOVA® GOTO Technology
  • Integrated ST-4 autoguiding port
  • Built-in 32-channel Global Positioning System (GPS)
