Atik 490EX

  • Low read noise
  • Excellent thermal management
  • Impressive sensitivity across a range of wavelengths
  • Fully regulated set-point cooling


The Atik 490EX combines high resolution imaging with the incredible sensitivity of the Sony ICX814 sensor and the versatility of the 4-Series design. The small 3,69 µm pixels are ideal for short-mid focal length telescope, while performing at multiple binning levels. This opens up the possibility of working at longer focal lengths and boosting sensitivity to capture even the faintest colour data.
