iOptron Mount CEM120 GoTo

Acknowledging the escalating demand for precise and robust equatorial mounts capable of accommodating larger instruments and intricate imaging setups, iOptron has engineered the CEM120. This mount harnesses the advantages of their pioneering center balance design, ensuring stability, accuracy, and seamless mechanical performance, all while supporting payloads of up to 52kg.

The inherent stability of the center balance design stems from aligning the mount and payload's weight directly over the center of the pier or tripod.

The CEM120 showcases its performance through minimal periodic tracking error. In addition to stability, it integrates an advanced cable management system with numerous ports strategically positioned to prevent entanglements and reduce the risk of cable damage. It introduces new features to the CEM series, such as Wi-Fi and LAN connectivity for remote operation, along with user-friendly, dependable clutches on both axes.

Key Features:

• Center-balanced equatorial mount (CEM) optimized for maximum payload capacity and natural stability
• Payload capacity of 52kg with a mount weight of only 26kg
• Easy-to-use and reliable gear clutches
• Precision altitude and azimuth adjustment
• Stepper motor with 0.07 arcsec accuracy for precise GOTO and tracking
• Polar alignment routine for users unable to locate the Pole Star
• Go2Nova® 8407 V2 controller with Advanced GOTONOVA® GOTO Technology and built-in heater
• Permanent periodic error correction (PPEC) or real-time PEC for the CEM120EC and CEM120EC2 versions
• 32-channel Global Positioning System (GPS)
• Built-in Wi-Fi and LAN for remote operation
• Integrated ST-4 autoguiding port
• Advanced cable management system offering multiple choices
• Spring-loaded, individually adjustable Losmandy saddle

The CEM120 is available in three versions: CEM120, CEM120EC, and CEM120EC2. The EC versions are equipped with high-resolution encoders for nearly error-free tracking, while the EC2 variant features encoders on both axes.
