Frame SEO description iOptron CEM70 EC<\/strong><\/h3>\n

The center-balanced equatorial mount iOptron CEM70 EC<\/strong> 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\u00ae control, this mount is the ideal choice for observing and imaging nebulae, galaxies and star clusters with maximum sharpness.<\/p>\n

Visit CEM70 EC<\/strong> is distinguished by :<\/p>\n

    \n
  • Load capacity of 31.8 kg (70 lb) to accommodate refractors, mirrors and heavy accessories.<\/li>\n
  • A total weight of 13.6 kg for the frame alone, making it easy to transport to dark-sky sites.<\/li>\n
  • High-precision stepper motors (0.07\u2033 per step) ensure smooth, silent tracking.<\/li>\n
  • Integrated iPolar port for electronic polar alignment, even in the presence of optical obstacles.<\/li>\n
  • A Go2Nova 8407+ V2 controller with a database of over 40,000 objects and advanced GOTO functions.<\/li>\n
  • A real-time periodic error correction (RPEC) system offering an accuracy of less than 0.3\u2033 RMS.<\/li>\n
  • All-metal mechanical design and ergonomic locking levers for use with gloves.<\/li>\n
  • A Vixen\/Losmandy double saddle for optimum compatibility with optical tubes and accessories.<\/li>\n<\/ul>\n

    Designed for demanding astrophotographers, the iOptron CEM70 EC<\/strong> 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\u00ae interface facilitates celestial navigation, and electronic polar alignment considerably reduces set-up time.<\/p>\n
