The iOptron CEM70EC is a center-balanced German equatorial mount engineered for serious astrophotographers and visual observers seeking high payload capacity with exceptional portability. Featuring a unique center-balanced design that places the payload at the mount's center of gravity, it delivers 70 pounds of payload capacity while weighing only 30 pounds, providing an outstanding 2.33:1 payload-to-weight ratio ideal for transporting to dark-sky sites. The EC model incorporates high-resolution encoders with real-time periodic error correction (RPEC), reducing periodic error from ±3.5 arcseconds to less than 0.3 arcseconds RMS, combined with iOptron's Go2Nova 8407+ hand controller featuring 359,000+ object database and integrated 32-channel GPS for precise celestial targeting and long-exposure astrophotography.
