84% QE
Back-Illuminated CMOS

The QHY183M and QHY183C use a 1-inch SONY back-illuminated IMX183 sensor with 20.48 million pixels at 2.4um. This sensor has high sensitivity with 84% QE and a read noise as low as one electron. The full well capacity is 15 - 16,000 electrons. Two-stage cooling yields -40C cooling delta. Because of the small pixels, high QE, good sensor size and the cooled design. The QHY183M/C is suitable for both DSO imaging and planetary imaging. And with the affordable price this camera is idea for both beginner and experienced astronomy photographer. Been selected as S&T magazine 2017 hot product and Astronomy magazine 2018 star product.

High Resolution

20.48 Megapixels
Planets and DSO

With 20.48 megapixels, high resolution 2.4 um pixel size and up to 19 FPS frame rate, this camera is ideal for EAA real-time deep space observation, lucky imaging of deep space objects by capturing and stacking many short exposures. This can take great advantage of high resolution telescope optics, reduce the effects of atmospheric jitter, and obtain deep-sky images with rich details and high resolution. At the same time, short exposure can also reduce the requirements for tracking accuracy making the night more productive.


4K Ultra HD
Video Support

Support 4096 × 2160 31FPS 4K Ultra HD 1:1 video output. In full resolution size it can output max 19FPS. In the ROI it can get much more higher in 8bit. This feature is idea for the planetary imaging and the astronomical live video broadcast.

Large Capacity Frame Buffer

Built-in 128MB
DDRII Image Cache

The QHY183M/C has built-in 128MB DDRII full frame buffer that can help tremendously with slower computers. It also helps with USB2.0 connections by avoiding loss of frames after exposure and improves the data transfer stability with flow control.

Cooled CMOS

1-Inch Format, 20.48MP
High Value for Money

Back-illuminated imaging technology places the circuitry and electrodes behind the pixels on the back of the sensor, avoiding reflection and loss of light. The QHY183M\C back-illuminated CMOS camera not only has the high sensitivity of a back-illuminated sensor, but also ultra-low read noise, as low as one electron, making this camera extremely cost-effective.


Support 4096 × 2160 31FPS 4K Ultra HD 1:1 video output.

Amp Glow Supression

QHYCCD has developed a CMOS glow suppression function that greatly eliminates the amplifier glow during long exposures.

Anti-Fog Window Design

Two-stage cooling reduces the sensor temperature to -40° C below ambient. But the optical window has a built-in heating plate to prevent condensation, even in humid environments.
