iOptron GEM28 German Equatorial Mount
with AccuAlign & 1.5" Tripod

The iOptron GEM28 is a perfect mount for users who are looking of a compact and portable mounting system that operates at higher latitudes. The mount only weighs 10 lb., yet it can support up to 28 lb.! That is an incredible 2.8 mount weight to payload ratio. It achieves this amazing feat by utilizing a similar design to that of the iOptron CEM mounts. In addition to the portable design, the GEM28 has many great features that are sure to wow observers and astrophotographers.

The mount is equipped with a positive lock gear engagement system that is easy to use with when users have gloves on. The body of the mount is all metal, CNC machined and it has a protective, black powder coating. When it comes to communication, the CEM26 mount comes with built-in WiFi that is unparalleled and an ST-4 auto-guiding port.

The GEM28 from iOptron utilizes a precision stepper motor for precise GoTo and accurate tracking. The GEM28's periodic error correction works to repeat optimal PEC training sessions. The included GoTo hand controller is the Go2Nova 8409 controller with advanced GoToNova GoTo technology. This GoTo technology comes complete with a 212,000 object library.

About the 1.5" Tripod

The included iOptron tripod has stable 1.5" diameter stainless steel legs. This is a solid tripod despite its light weight and easy portability that compliments the portability of the GEM28. Additional features include a die-cast aluminum top and ABS three prong spreader for reliable support.
