Frame SEO description iOptron CEM70 EC2

The center-balanced equatorial mount iOptron CEM70 EC2 is specially designed for demanding astrophotographers looking for the highest precision in long exposure imaging. Thanks to its dual system of high-resolution encoders on the right ascension and declination axes, it offers periodic real-time error correction on both axes, guaranteeing perfectly sharp images with no star trails. Its Center-Balanced Equatorial Mount architecture minimizes vibrations and optimizes stability, while retaining appreciable portability for transport in the field.

Visit CEM70 EC2 is distinguished by :

  • Load capacity of 31.8 kg (70 lb) to accommodate optical tubes and heavy accessories.
  • A frame weight of 13.6 kg offering an excellent load/weight ratio for maximum portability.
  • Two high-resolution encoders (AD & DEC axes) for bidirectional periodic error correction.
  • Ultra-precise stepper motors (0.07″ per step) ensure smooth, silent tracking.
  • A Go2Nova 8407+ V2 controller with over 40,000 database objects and advanced GOTO functions.
  • Integrated iPolar electronic polar alignment, even in limited fields.
  • A dual Vixen/Losmandy saddle system for universal compatibility.
  • Dual-axis real-time periodic corrector (PEC) for accuracy below 0.3″ RMS.
