The ASI183MC features high-speed and high-picture quality rolling shutter-type back-illuminated CMOS image sensors
In the astronomic application field, Sony's IMX183CLK-J (monochrome) and IMX183CQJ-J (color) sensors use a very high sensitivity back-illuminated structure with high resolution 2.4 um square unit pixel. The optical pixel array size is 1 inch.
Astrophotography Performance
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.
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.

12bit ADC
5496×3672 19fps
3840×2160 36.12fps
1920×1080 70.48fps
1280×720 103.23fps
High QE
Sony's back-illuminated Exmor R technology gives excellent deep sky performance. The ASI183MC's QE peak reaches a remarkable 84%. In the Ha channel, QE is over 60%.
Having high QE means more of the light that enters your telescope and reaches the sensor is actually used. With 84% peak Q.E. and no less than ~50% within the visible spectrum, the ASI183MC will utilize a high percentage of the light that reaches it, improving your signal quality.
USB 3.0 Port & ST4 Port
USB 3.0 Port: This port provides 5Gb bandwidth to make it possible for the ASI183 to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution (20.18 megapixels).
ST4 Port: Connect with your mount's auto guide port
