The ASI183 camera series, the most sensitive cameras in ZWO history. Peak Q.E. of the mono sensor reaches 84%!
Diagonal 15.86 mm Approx. 20.48M-Effective Pixel Monochrome/Color CMOS Image Sensor
High-Speed and High-Picture-Quality Rolling Shutter-Type Back-Illuminated CMOS Image Sensors
In the astronomical application field, Sony IMX183CLK-J (monochrome) and IMX183CQJ-J (color) sensors use a very high sensitivity back-illuminated structure with high resolution 2.4 μm square unit pixel. The optical size is 1 inch.
DDR Memory Buffer
The ASI183 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.
The DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.
The ASI183 cameras have a very large full well capacity（15000e） for such a small pixel size, 1.6e read noise @ 30DB, and 12stops dynamic range @ Gain=0. The ASI183 cameras also utilize firmware features to minimize amplifier glow for maximum performance in astrophotography.
ASI183 Pro has the same mechanics as ASI1600 Pro. There are four screws that seal the sensor chamber. The camera design has been extensively tested and is very stable.
Even when used in higher humidity environments, the ASI183 Pro will still work fine without dew problems.
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, imaging of double stars and other small objects, planetary imaging of the major planets in the solar system, and much more.
Sony’s back-illuminated Exmor R technology gives excellent Deep Sky performance. ASI183 QE peak reaches a remarkable 84%. In the 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.
The dark current of the ASI183 is extremely low, based on test results.

USB 3.0 Port & USB2.0 HUB
USB 3.0 Port: Provides 5Gb bandwidth to make it possible for ASI183 Pro to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution (20.18 Mega).
USB 2.0 HUB: Can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can better manage your cables. The ASI183 Pro includes two short 0.5m USB 2.0 cables. The integrated USB 2.0 hub is powered by the external power source if you connect one.
The ASI183 Pro has a 2-stage TEC cooling system that enables deep cooling (40°C-45°C below ambient). The cooler requires an external power supply, which is not included with the camera.
Recommended cooler power supply: 12V @ 3-5A (or more) DC adapter (2.1×5.5mm, center pole positive). Also suitable: DC battery with 9-15V.
Using a battery with 9-15V is also suitable for the cooler power supply.
