The iOptron GEM45EC is a compact German equatorial mount engineered for astrophotographers and visual observers seeking observatory-grade tracking in a portable package. Equipped with high-resolution encoders and Real-Time Periodic Error Correction (RPEC), it delivers exceptional sub-arcsecond tracking accuracy ideal for long-exposure imaging without the need for autoguider training. The mount's integrated iPolar electronic polar scope enables precise polar alignment even when the pole star is obscured, while the Go2Nova 8407+ controller provides access to 212,000+ celestial objects with automated GoTo and tracking capabilities. Built on a lightweight CNC-machined aluminum frame weighing just 17.5 pounds, it maintains an impressive payload-to-weight ratio while supporting up to 45 pounds of equipment, making it an excellent choice for both mobile deep-sky imaging rigs and semi-permanent observatory installations.
