    iOptron CEM40EC Center Balance Equatorial Mount and 1.25" Tripod

    The CEM40 is an equatorial mount that is sure to wow and delight astrophotographers and visual observers. The mount is a medium-sized, GoTo equatorial mount with a weight capacity of 40lb. The kicker? This mount only weighs 15.8lb! The impressive accuracy of the high-resolution RA encoder is <0.25 arc-seconds. It also includes the iPolar which is an integrated electronic polar finder that will make alignment super easy, a Universal Self-Centering Saddle that accepts both Losmandy and Vixen-style dovetail plates, GPS, an internal cable management system, and much more!

    Traditional equatorial mounts are wonderful when it comes to both visual astronomy and astrophotography, but sometimes users have had to deal with the fact that the design causes torque that effects the mount's overall stability. The iOptron CEM, or Center Balance Equatorial Mount, places the mount's balance point directly over the tripod, resulting in greater stability and allowing for a better weight capacity to mount weight ratio. This iOptron mount design is one of the reasons why the CEM40EC mount head can weigh just 15.8 pounds but carry up to 40 pounds!
