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!
This mount also has an integrated electronic polar finder scope known as the iPolar. This tool ensures the accurate alignment of a telescope, even when the pole star is obscured. There are large levers on the quick-lock drive engagement system; these large levers make it easy to snap the gears into place.
Innovative iOptron TechnologyMake 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 FeaturesThe 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.
With the included tripod, 10lbs. counterweight, and the mount's computerized technology, observers are just an OTA away from a spectacular viewing experience!FeaturesUnique design, Center-Balanced equatorial mount (CEM) for maximum payload and minimum mount weightIdea for both visual observation and astrophotographyMaximum payload of 40 lbs (18 kg) with the mount weight of only 15.8 lbs (7.2 kg)All metal, CNC machined with red/black anodizedEasy to use quick-lock gear clutchesIntegrated iPolarTM electronic polar finderLow periodic error (< ± 7 arc seconds)Permanent periodic error correction (PPEC)Precision stepper motor for precise GOTO and accurate trackingGo2Nova® 8407+ controller with Advanced GOTONOVA® GOTO Technology with built-in heaterIntegrated ST-4 autoguiding port32-channel Global Positioning System (GPS)USB communication portCable management systemNew, patent-pending iOptron universal saddleStandard 1.5 inch heavy-duty stainless steel tripod (5kg)Optional WiFi for mount control via SmartPhone/Tablet/Computer
I moved up to this from an EQ5 with AstroEQ motor drives. I had a couple of initial teething problems (tripod leg locks and calibrating the iPolar) but these were easily resolved and since then this mount has been a delight. I've been using it now for almost 4 months. It carries an RC6, guidescope, a main cam, guide cam and a motor focuser. Guiding performance is mainly affected by seeing (no surprise) but on the best nights the mount will track at around 0.5 arcsec RMS for extended periods. It is worth ensuring that the saddle clamps are adjusted laterally so your scope is perfectly balanced in all 3 axes. Balance is very easy to find accurately since with the locks off, the mount moves really smoothly and freely. Dec backlash is very low. Not needed to adjust belt tension or gear mesh, though instructions for both are online and look easy to follow.Mount is computer controlled via the iOptron commander software into ascom clients on a windows 10/64 machine, Everything just works, no problems. All in all a beautifully made, high performance piece of equipment. Not cheap but worth it.
