Note：ZWO Cooled cameras require a 12V power source for the TEC cooler and USB hub power. If you don’t have one, please add it through the options on the right side of the product display.
Introducing the ASI183 camera series, the most sensitive cameras in ZWO history. Peak QE of the mono sensor reaches 84%! This camera uses the IMX183CLK-J monochrome sensor
Diagonal 15.86 mm approx. 20.48MB effective pixel IMX183CLK-J Monochrome/
IMX183CQJ Color CMOS image sensors, featuring high-speed and high-picture-quality rolling shutter-type back-illuminated CMOS image sensors
In the astronomic application field, Sony 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 size is 1 inch.
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 non-Pro and Pro cameras, along with the cooling in the Pros.
The ASI183 cameras has a very large full well capacity（15000e） for such 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 same mechanics as ASI1600 Pro. There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable. Even when used in higher humidity environments, ASI183 Pro will still work fine without dew problems.
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.
The 10Bit ADC provides:
Sony’s back-illuminated Exmor R technology, 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. 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 our 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(20.18MB).
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. You may order a suitable power supply.
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.
