The iOptron CEM120 EC2 is a precision-engineered, center-balanced equatorial GoTo mount designed for demanding astrophotographers and observatories requiring research-grade tracking accuracy. Featuring dual high-resolution encoders on both RA and declination axes, it delivers sub-arcsecond tracking accuracy of less than 0.15 arcseconds RMS with real-time periodic error correction (RPEC), enabling unguided imaging and long-exposure astrophotography. With a 115-pound payload capacity and intelligent center-balanced architecture that places the telescope's weight directly over the tripod or pier, this mount offers exceptional stability and one of the best load-to-weight ratios in the industry, making it ideal for large refractors, astrographs, and multi-instrument setups in permanent installations and automated observatories.
