Product description

The new compact next generation German mount from iOptron - the GEM28! Like its predecessors, the GEM28 was designed with mobility in mind. Weighing only 4.5 kg, it can carry up to 12.7 kg of payload.

Building on the legacy of previous GEM models, iOptron has added attractive features for greater convenience and functionality.

  • A gear engagement system with positive locking (easy to operate even with gloves on)--.
  • Integrated Wi-Fi, which provides unparalleled connectivity.
  • A storable permanent periodic error correction (PPEC) for repeating optimal PEC training sessions. This improves tracking accuracy for astrophotography.
  • Fast polar alignment through the optical polar scope AccuAlign
  • An electronic polar alignment method for those who do not have a clear view of Polaris.
  • CNC-machined and cast metal housing.
  • Large, easy-to-use quick-release couplings
  • Integrated ST-4 autoguiding connector
  • Built-in Wi-Fi
  • USB port for firmware upgrade and computer control
  • Deluxe LiteRoc tripod (7.5 kg)
  • Die-cast metal tripod spider with accessory tray
  • Optional 32-channel GPS (Global Positioning System)



The GEM28 is equipped with the latest advanced GOTONOVA® GOTO technology

This makes it one of the most powerful and accurate GOTO mounts on the market. The library of 212,000 entries ensures that you will never run out of objects to see or image. The Go2Nova® handheld controller is intuitive to use and its large 4-line LCD screen simplifies telescope setup and object finding.

Tripod Connection:

The mount is attached to the tripod from above with two M6 screws (see illustration). This allows an easy adaptation to own tripod constructions or also pier adapters.
