ZWO ASI183MC 20.2MP USB 3.0 Color Astronomy Camera

IMX183CQJ-J Sensor
Diagonal 15.86mm Approx. 20.48M-Effective Pixel Color CMOS Image Sensor

High-Speed and High-Picture-Quality Rolling Shutter-Type Back-Illuminated CMOS Image Sensors
In the astronomic application field, Sony IMX183CQJ-J (color) sensors use a very high sensitivity back-illuminated structure with high resolution 2.4 microm square unit pixel. The optical size is 1".

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 (white light) 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.

10bit ADC
• 5496 x3672 19fps
• 3840 x2160 41.04fps
• 1920 x1080 80.10fps
• 1280 x720 117.30fps

12bit ADC
• 5496 x3672 19fps
• 3840 x2160 36.12fps
• 1920 x1080 70.48fps
• 1280 x720 103.23fps

High QE
Sony's back-illuminated Exmor R technology gives 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. With 84% peak Q.E. and no less than -50% within the visible spectrum, the ASI183 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
Provides 5Gb bandwidth to enable ASI183 to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution (20.18Mega).

ST4 Port
Can be used to connect with auto guide port of mount for guiding.
