Frame SEO description iOptron CEM70 EC

The center-balanced equatorial mount iOptron CEM70 EC is designed for astronomy and astrophotography enthusiasts looking for a high-performance, stable and relatively portable solution. Its innovative Center-Balanced Equatorial Mount architecture reduces vibrations and enables precise tracking of celestial objects, even at long exposures. Thanks to its high load-to-weight ratio and Go2Nova® control, this mount is the ideal choice for observing and imaging nebulae, galaxies and star clusters with maximum sharpness.

Visit CEM70 EC is distinguished by :

  • Load capacity of 31.8 kg (70 lb) to accommodate refractors, mirrors and heavy accessories.
  • A total weight of 13.6 kg for the frame alone, making it easy to transport to dark-sky sites.
  • High-precision stepper motors (0.07″ per step) ensure smooth, silent tracking.
  • Integrated iPolar port for electronic polar alignment, even in the presence of optical obstacles.
  • A Go2Nova 8407+ V2 controller with a database of over 40,000 objects and advanced GOTO functions.
  • A real-time periodic error correction (RPEC) system offering an accuracy of less than 0.3″ RMS.
  • All-metal mechanical design and ergonomic locking levers for use with gloves.
  • A Vixen/Losmandy double saddle for optimum compatibility with optical tubes and accessories.

Designed for demanding astrophotographers, the iOptron CEM70 EC offers an optimum balance between performance, portability and robustness. Its load-to-weight ratio allows heavy configurations to be carried without sacrificing stability, while precise tracking and real-time correction guarantee sharp images without star trails. The Go2Nova® interface facilitates celestial navigation, and electronic polar alignment considerably reduces set-up time.

Comparison CEM70 EC vs. CEM70 EC2

Criteria CEM70 EC CEM70 EC2
Encoders 1 high-resolution encoder (AD axis) 2 high-resolution encoders (AD & DEC axes)
Periodic error correction On a single axis (AD) in real time On both axes (AD & DEC) in real time
Long exposure precision Excellent Optimal (greater resistance to imbalances)
Vibration resistance High Maximum (dual sensors)
Recommended use Advanced astrophotography Very long exposure astrophotography & deep imaging
Price guide More affordable Slightly higher

In short, the CEM70 EC is a powerful choice for most astrophotography configurations, offering precise tracking and good value for money. The CEM70 EC2 gains in robustness and precision thanks to its dual encoder system, making it the mount of choice for extreme long exposure imaging projects or for astrophotographers seeking the best periodic error correction on both axes.
