The iOptron® CEM40 mount is the next generation of center-balanced equatorial mounts. This mount is incredibly eye-pleasing, and its beauty is found in more than its appearance. The functionality of the mount is superb. Weighing in at only 15.8lbs., this mount can support a payload of up to 40lbs.! That's incredible!

Innovative iOptron Technology
Make way for an innovative mount! This iOptron CEM40 mount uses iOptron's patent-pending Universal Self-Centering Saddle (USCS). This saddle accommodates Losmandy and Vixen-style dovetail plates. The CEM40 also uses iOptron's ultra-quiet, low-power consumption stepper motor drive system, aiding the mount in providing precise tracking.

Computerized Mount Features
The iOptron CEM40 mount uses the Go2Nova® 8407 hand controller to navigate the night sky. This incredible technology helps observers find celestial objects with the aid of the mount's 212,000+ object database! For those looking for a telescope that has the capability of tracking and finding beautiful night sky objects, this mount is a must have tool.

If you choose iOptron electronics polar scope, iPolarTM, it ensures the accurate alignment of the mount, even when the pole star is obscured. You may also choose iOptron AccuAlignTM optical polar scope. There are large levers on the quick-lock drive engagement system; these large levers make it easy to snap the gears into place.

Polar scope, tripod and counterweight are not included.

Excellent hardware and maturing software works well
Monday, 17 February 2020  | 

I was one if the first to get the CEM40 in the UK and after about 9M use I am really pleased with it. I was attracted to it by the good payload to weight ratio and the integrated ipolar polar alignment tool.

Ipolar was a bit clunky at first, with odd gremlins in the Windows only application. This software has now matured significantly, and I am writing this now based on Windows V2.1 and MacOS version 1.1, which have a common newer version of the plate solving engine. I am getting good calibrations with both versions. They work almost identically. It would be great if iOptron could sort out a version to use with a phone, even if wired, as that would make ipolar-enabled mounts still more usable for people who do not want to take a laptop out. But it takes me only a few minutes, sometimes just two, to secure polar alignment, followed by a solid 3 star goto alignment.

The mount hardware has dealt with everything from a small lens plus camera to a 107mm refractor and a loaded 6in SCT, though Iím sure it could take more. Iíve got the 2in tripod which is solid. I added a smaller
Counterweight for balancing lighter loads.

Having the polar alignment camera along the axis of rotation and usable with the mount fully loaded means I can recheck alignment whenever I need to. If it has slipped on rough or wet ground, or Iíve kicked it in the dark, it only takes a couple of minutes to adjust.

The GPS module captures location quickly and the hand controller behaves fine, with a large database of catalogues of objects. The whole system runs fine of a Tracer battery.

Iíd give it 5 stars if there was an iPhone version of the ipolar app. IOptron said it was on the way back in mid 1019! I canít comment on the EC version as mine is non EC, but adding a guide camera is the next step.
