ZWO ASI 178 Color CMOS Telescope Camera

This ZWO ASI178MC Astronomy Camera includes the back illuminated 6.4M resolution Sony IMX178 image sensor. This 1/1.8 inch CMOS sensor has a 3096 x 2080 pixel array and a 2.4 micrometer square pixel size. With a 14-bit ADC, extremely low read noise of 2.2e, and superior sensitivity combine to make the ZWO ASI178MC an excellent camera for both astronomy and microscopy.


Sony IMX178 CMOS Sensor Features:

  • The Sony IMX178 back illuminated CMOS image sensor offers high sensitivity, resolution and dynamic range.
  • The IMX185 is an "Exmor R" sensor with notably improved imaging features, including sensitivity and low read noise, by correcting the basic structure of "Exmor" adopted column parallel A/D converter to back illuminated type.
  • The IMX178 is a Sony STARVIS sensor and has a sensitivity of 2000mV+ per 1 micron square (when imaging with a 706 cd/m2 light source, f/5.6 in 1 second accumulation correspondent), and provides superior image quality in the visible and near IR light regions.
  • 14-bit output helps achieve high dynamic range which lessened quantization noise and hidden dark random noise. This facilitates clear image quality in light and dark areas, even with high contrast imaging targets.
  • Everything required to control your ZWO Astronomy Camera is readily available at the ZWO website.
