Frame iOptron CEM120 (Standard)<\/strong><\/h3>\n

The center-balanced equatorial mount iOptron CEM120<\/strong> he standard version is designed for astronomers and astrophotographers wishing to combine high payload capacity with mechanical robustness. With a payload of up to 54.4 kg (120 lb), it can support large, heavily-equipped catadioptric or dobson telescopes. Its Center-Balanced Equatorial Mount design reduces vibration while ensuring smooth, precise tracking for visual observation and short-to-medium exposures.<\/p>\n

    \n
  • Load capacity: 54.4 kg (120 lb)<\/li>\n
  • Frame weight: approx. 23 kg<\/li>\n
  • Load\/weight ratio: ~2.4<\/li>\n
  • Hardened steel axles with sealed ball bearings<\/li>\n
  • Manual azimuth and latitude controls<\/li>\n
  • Vixen\/Losmandy double saddle for universal compatibility<\/li>\n
  • Adjustable tubular steel feet<\/li>\n<\/ul>\n

    Ideal for heavy visual observation configurations, the standard version of the CEM120 offers a stable base with no on-board electronics, allowing the user to integrate the tracking or encoder system of his choice. Its all-metal design guarantees long life and optimum rigidity when installing large optical tubes.<\/p>\n

    Frame iOptron CEM120 EC<\/strong><\/h3>\n

    Visit CEM120 EC<\/strong> incorporates a high-resolution encoder on the right ascension axis to provide real-time periodic error correction (RPEC). Combined with the Go2Nova\u00ae 8408 controller, this version enables more precise tracking over long exposures, without the need for external autoguiding, for sessions lasting up to a few minutes.<\/p>\n

      \n
    • High-resolution encoder on AD axis for unidirectional PEC correction<\/li>\n
    • Go2Nova 8408 controller with 40,000+ object database<\/li>\n
    • Integrated tracking for up to 5 minutes without autoguiding<\/li>\n
    • Optional iPolar polar alignment<\/li>\n
    • Cable management system and ergonomic locking levers<\/li>\n<\/ul>\n

      The EC version retains the mechanical features of the standard CEM120 while adding high-performance on-board electronics, ideal for moderate to advanced astrophotography without immediately investing in an autoguider. Real-time PEC correction significantly improves tracking accuracy and reduces image artifacts.<\/p>\n

      Frame iOptron CEM120 EC2<\/strong><\/h3>\n

      Visit CEM120 EC2<\/strong> goes one step further by integrating two high-resolution encoders (AD and DEC axes) for real-time bidirectional correction, offering maximum stability and precision for long exposure astrophotography and deep imaging. Combined with the Go2Nova 8408+ controller, it meets the requirements of the most demanding imaging projects.<\/p>\n

        \n
      • Dual high-resolution encoders on AD & DEC axes<\/li>\n
      • Bidirectional periodic corrector (PEC) < 0.3\u2033 RMS on both axes<\/li>\n
      • Reliable tracking in long exposures (10+ minutes) with or without autoguiding<\/li>\n
      • Go2Nova 8408+ controller with USB port and integrated Wi-Fi<\/li>\n
      • Integrated iPolar polar alignment for ultra-fast stationing<\/li>\n<\/ul>\n

        Designed for deep imaging, the CEM120 EC2 offers exceptional resistance to imbalance and vibration thanks to its dual-axis sensors, guaranteeing uncompromising image quality. It reduces the need for external corrections and simplifies the workflow of professional astrophotographers.<\/p>\n
