iOptron CEM25EC Equatorial Mount w/ 1.5" Tripod & Hard Case

This center-balanced iOptron CEM25EC Mount is a smooth, lightweight equatorial mount that consumes up to 60 percent less GoTo power when compared with similar mounts.

This iOptron equatorial mount features a high precision optical encoder system with advanced control electronics. The CEM25EC will track a star at a periodic error less than 0.3 arc second.

This mount's "Z" design places the payload weight at the center of mass, providing better natural balance. At only 10.4 lb, the CEM25 is remarkably light given its 27 lb payload capacity. This comes in handy when having to set up at a remote location. Additional features include an adjustable counterweight bar to avoid interference with the tripod and polar alignment that is quick and available at all times since it's not impeded by the declination shaft.

The CEM25 is outfitted with the most advanced GoToNova Go-To technology, making it one of the top GoTo mounts on the market in terms of power and accuracy. Its database features more than 59,000 objects. With its large 4-line LCD screen, the GoToNova controller is a user-friendly tool that streamlines the process of setting telescopes and finding objects in the night sky.

Nice new mount

So far, so good. Needed two additional counterweights from an old mount. Mount rated to 27 pounds but needed more to get scope balanced.
