DESCRIPTION

The GEM28 from iOptron is a compact next-generation German equatorial mount designed for portability and performance. Weighing only 4.5 kg, it can carry up to 12.7 kg, thanks to a mass-optimized design inspired by iOptron’s CEM mounts.

It features an easy-to-use positive lock gear system, integrated Wi-Fi, recordable permanent periodic error correction (PPEC), and the iPolar electronic polar scope which allows accurate alignment even when Polaris is not visible.

The Go2Nova system includes 212,000 objects and an intuitive 4-line LCD controller. Accurate pointing, reliable tracking, and full connectivity (ST-4, USB) make it ideal for advanced use. It ships with a rugged 1.5" stainless steel tripod. Two boxes included: mount head with tray and separate tripod.
