The ASI 183 camera series is the most sensitivie cameras in ZWO history. Peak Q.E. of the mono sensor reaches 84%!

Astrophotography Performance

In the astronomic application field, Sony IMX183CLK-J (monochrome) and IMX183CQJ-J (color) sensors uses a very high sensitivity back-illuminated structure with high resolution 2.4 μm square unit pixel. The ASI183 cameras have a very large full well capacity （15000e） for such small pixel size, 1.6e read noise @ 30DB, and 12 stops dynamic range @ Gain=0. The ASI183 cameras also utilize firmware features to minimize amplifier glow for maximum performance in astrophotography.

Sony’s back-illuminated Exmor R technology is giving it excellent Deep Sky performance. ASI183 QE peak reaches a remarkable 84%. In Ha channel, QE is still over 60%. Having high QE means more of the light that enters your telescope and reaches the sensor is actually used. The ASI183 will utilize a high percentage of the light that reaches it, improving your signal quality.

High Speed

Fast FPS can be used in solar and lunar imaging, as well as for live viewing/EAA. The high speed readout may also be used for real-time focusing, true lucky imaging of double stars and other small objects, planetary imaging of the major planets in the solar system, and much more.

Colour or mono? Black and white cameras have the advantage of higher sensitivity and resolution than colour cameras. However, more effort is required to obtain a colour image. You also need colour filters and a filter wheel
