Like their predecessors, the GEM28 is designed with portability in mind, weighing in at only 10 lbs it can support up to a 28lb payload an incredible 2.8 mount weight to payload ratio. We achieved this using design methods developed to reduce mount mass in our CEM family of mounts. The German EQ versions were created to satisfy consumer that prefer a more traditional mount and to function at higher latitudes.
Building on the legacy of earlier GEM models we have added features for convenience and functionality. A positive lock gear engagement system (easy to use even when wearing gloves), Built-in Wi-Fi enabling unparallel connectivity and recordable permanent periodic error correction (PPEC) to repeat optimal PEC training sessions. Regarding functionality the GEM28 delivers precise pointing and accurate tracking. The GEM28 sets the new standard for compact German equatorial goto mounts.
The GEM28 is equipped with the latest advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. The 212,000 object library ensures you’ll never run out of targets to see or image. The Go2Nova® Hand Controller is intuitive to use and its large 4-line LCD screen simplifies the process of setting telescopes and locating objects.

Our expert comment:
The iPolar is built in a way that the virtual pole on your screen will move towards the left / right direction, while the adjustment of the Azimuth screws is being done during polar alignment. This does not affect accuracy at all.

The thumb turns on the side of the GEM28’s top plate/prism clamp are designed not to stick out much so that, on some models of this mount, the turn may become stuck in or scrape against the casing for the declination axis. Here, 1-2 hard plastic or metal washers can be used to fix this issue. The washers increase the distance between the thumb turn and the casing.
