iOptron Mount GEM28 GoTo iPolar LiteRoc (69717)

The iOptron GEM28 is a lightweight German equatorial mount designed for portability and performance, weighing only 4.5 kg (10 lbs) while supporting a payload of up to 12.7 kg (28 lbs). With an impressive 2.8 mount weight-to-payload ratio, the GEM28 is ideal for both mobile setups and astrophotography. Its design incorporates advanced engineering methods from the CEM family to reduce mass while maintaining stability. The GEM28 is particularly suited for use at higher latitudes, with a latitude range of 10° to 70°.

Building on the legacy of earlier GEM models, the GEM28 introduces enhanced features for convenience and functionality. It includes a positive lock gear engagement system that is easy to operate even with gloves, built-in Wi-Fi for seamless connectivity, and recordable permanent periodic error correction (PPEC) for optimal tracking performance. The mount delivers precise pointing and accurate tracking, setting a new standard for compact German equatorial GoTo mounts.
