ZWO ASI183MM-P Monochrome Cooled USB Camera

SKU: ASI183MM-P Categories: , ,

The ASI 183 MM Pro Monochrome Cooled USB Camera is ideal for Deep Space Photography.

Monochrome camera sensors are capable of higher detail and sensitivity than is possible with color sensors, but you need additional accessories such as filter wheel and filters for producing colour astrophotography images.

Key features:

  • Colour or Monochromatic: Monochrome
  • Fan Cooled: Yes
  • Sensor Model: IMX183CLK-J, CMOS
  • Sensor Size: 1 inch
  • Resolution: 5496 x 3672
  • Megapixel: 20
  • Pixel Size: 2.4 micrometers (µm)
  • Quantum Efficiency (QE) Peak: 84 %
  • (Max) Analogue to Digital Converter Resolution: 12 bit

The ASI183MM Pro uses Sony’s IMX183CQJ-J sensor. With a high QE-value and low provides excellent image quality at an affordable price.

Some of the features include:

  • 20 megapixel sensor with 2.4 μm pixel size. – able to capture19 frames/s frame rate in 12-bit mode with high detail
  • Very low 6e- readout noise – bringing out more details in your images with improved dynamic range
  • Full-well capacity of 15ke– – reduces the risk of over saturated stars in longer exposures
  • A 256MB DDR3 memory buffer to help improve data transfer reliability.


Why Monochrome?

A monochrome astrophotography camera can collect more signal (light) than a color camera can. (3 times as much, to be exact).

All the Light wells on a camera chip are monochrome. They can’t themselves differentiate between red, green or blue photons.

The Bayer filter array found in a color camera reduces the amount of overall light recorded on your image.
