The iOptron GEM28 is a compact German equatorial GoTo mount designed for both visual observation and astrophotography with small to medium-sized telescopes. Weighing just 10 pounds while supporting payloads up to 28 pounds, it delivers an exceptional 2.8:1 mount-to-payload ratio for portable deep-sky imaging and viewing. Features include the advanced Go2Nova 8409 GoTo controller with a 212,000-object database, stepper motors with precision tracking, built-in Wi-Fi, integrated iPolar or optional AccuAlign polar scope, and permanent periodic error correction (PPEC) for optimized tracking performance. The mount's German equatorial design operates across latitudes from 10° to 70°, making it ideal for travel-friendly astrophotography setups with ED refractors, compact Newtonians, or lightweight imaging cameras.
