Product Description

The iOptron CEM60, has a maximum payload of 27kg (60 lbs) and a mount-only weight of 12.3 kg (27lbs). Not only does the CEM60 have an amazing weight to payload capacity, it also outperforms similar size mounts costing several times the price in accuracy, with all the advanced imaging-friendly features you could wish for. The recommended imaging weight depends on your optical tube length and shape, focal length and of course the focal ratio and pixel size of your camera. Refractors and telescopes with long optical tubes produce more torque on the mount (increased moment-arm and leverage) therefore it is difficult to give an exact maximum rating for imaging because dampening time may be longer with a lengthy tube than say, with a compact Ritchey Chretien. Always talk to your dealer for advice.
 
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 payload with a payload-to-weight ratio of 2.2. That's why the CEM60 is a good choice for both portable field setup, AND 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.

Mounting options summary:
- Optional iOptron 2" Stainless Steel tripod (8kg) - recommended for use with a light OTA up to 800mm focal length.
- Optional iOptron Portable Field Pier (10kg) - recommended for medium weight OTAs up to 1200mm focal length.
- Altair Starwave Field Pier / Tripod (17.5kg) - the ultimate for image-sharpness with any OTA the mount can support.
- Optional SkyShed Altair 8" Steel Observatory Pier System (40kg) - as above, for semi-permanent outtdoor installation on a patio or decking, or permanent observatory use.

For the ultimate in stability, consider the ultra-stable Altair Starbase Field Pier / Tripod, which sets a new standard for freedom from flex, strength and stability. For permanent mounting, consider the Altair/SkyShed 8" Steel Observatory Pier, with a unique design, making it the easiest-to-install pier on the market. (See thumbnail images and ordering options).
