The first image contains the mount and the variant option iOptron Tri-Pier.

The CEM60 puts the weight of the payload at the center of gravity allowing for greater natural stability. This makes the mount extremely light compared to its maximum payload with a payload-to-weight ratio of 2.2. That's why the CEM60 is a good choice for both portable field setup, or permanent observatory use.
The CEM60 redefines the concept of the equatorial mount for viewing and astrophotography by placing the load between two precision engineering main bearings. This improves tracking accuracy compared to conventional mounts where the bearings are placed comparatively far away from the load.

Two versions of the CEM60 are available. The CEM60 which is the "Standard" model with Programmable Periodic Error Correction (PPEC) and the CEM60 "Advanced" model with optional Real-Time PEC for incredibly high tracking accuracy, intended for customers with longer focal length instruments, or those who want the very best tracking performance available. Either mount still offers simply amazing performance in it's class.

The iOptron CEM60 mount features a large dual 1.75" / 3" dovetail clamp for convenient use of most telescopes on the market. Other features include an adjustable counterweight bar to prevent obstruction with the tripod or pier. Polar alignment is quick and easy with the AccuAligningTM polar scope, which can be viewed-through regardless of where the mount is pointing, because it isn't blocked by the declination shaft.

The CEM60 is equipped with the most advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. The CEM database includes over 300,000 objects. The Go2Nova® Hand Controller is intuitive to use and its large 8-line LCD screen simplifies the process of setting telescopes and locating objects. 

Another feature is through-cabling to reduce the number of cables around your telescope and imaging accessories. 2x 12v power-out ports and 4x USB ports are conveniently placed just below the dovetail clamp on the mount's RA axis.

CEM60 Features:

  • A new design, center-balanced equatorial mount (CEM) for maximum payload and minimum mount weight
  • Specialized astrophotography mount ideal for entry-level and intermediate Astro-photographers
