Like their predecessors, the GEM28 mounts were designed with portability in mind, weighing in at only 10 lb. But, it can support up to a 28 lb payload; an incredible 2.8 mount weight-to-payload ratio. The key to providing such an impressive ratio was the engineering skills used to reduce the mount weight. The German Equatorial design mount was created and offered for those astronomers who want the traditional German mount. Other features include a mount design which can function at latitudes over 60°, as well as accurate pointing and tracking.
In addition, iOptron has added features for convenience and functionality. A positive lock gear engagement system (easy to use even when wearing gloves), built-in Wi-Fi, enabling unparalleled connectivity, and recordable permanent periodic error correction (PPEC) to repeat optimal PEC training sessions. The GEM28, Model G28BC German Equatorial Mount from iOptron delivers precise pointing and accurate tracking. The GEM28, Model G28BC sets a new standard for compact GoTo equatorial mounts.
The iOptron GEM28, Model G28BC Equatorial Mount is equipped with the latest advanced GOTONova GO-TO technology, which means it is now one of the most powerful and accurate GO-TO mounts available. Its database includes over 212,000+ objects! The Go2Nova Hand Controller is intuitive and very easy to use. Its large 4-line LCD screen simplifies the process of setting telescope parameters and locating objects, to make the astronomer's task even easier. This GEM28, Model G28BC German Equatorial mount from iOptron will be a delight to use for all of your astronomical observations, including for doing astro-imaging.
This GEM28, Model G28BC mount has an AccuAlign Optical Polar Scope installed for quick and easy polar alignment. It also includes a 1.5" heavy duty stainless steel tripod and a Hard Case for storage and transportation.
