ASI183MC Pro uses Sony’s IMX183CQJ-J sensor. With a high QE-value and low provides excellent image quality at an affordable price. Some of the features include:
This back-illuminated, rolling shutter-type CMOS sensor has a diagonal of 15.86 mm and approximately 20.2 megapixels.
Designed for astrophotography, the Sony IMX183CLK-J (monochrome) and IMX183CQJ-J (color) sensors use high sensitivity back-illuminated structures with high resolution 2.4 μm square pixels. 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 ASI “Cool” and “Pro” cameras.

The ASI183 cameras has an impressive list of characteristics suited for astrophotography including a large full well capacity of 15000 e-, 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.
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 in demanding environments.
Even when used in environments with higher humidity, ASI183 Pro will still work fine without dew problems.
Fast FPS and high-speed readout come in handy for many applications in astrophotography such as in
Sony’s back-illuminated Exmor R technology, giving it excellent Deep Sky performance. ASI183 QE peak reaches a respectable 84%. In Ha channel, QE is still over 60%.
Having high QE means that 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.
Dark frame sample @ Highest dynamic range settings(gain=0), 300s, -10°C, bin1. Please check the dark frame to make sure you are fully aware of the performance.
USB 3.0 Port: Provide 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(20.18Mega).
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.
Thanks to the two stage TEC cooling, ASI183MC Pro can lower the sensor temperature to 40-45 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
