ASI183 camera series product shot

Introducing the ASI183 camera series, the most sensitive cameras in ZWO history. Peak Q.E. of the mono sensor reaches 84%!

▶ IMX183CLK-J/CQJ-J Sensor

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 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 μm square unit pixel. The optical size is 1 inch.

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.

Notice: According to user feedback, this IMX183 sensor has grid pattern noise when doing Ha solar imaging. Please take flat frames for calibration (out of focus or add a barlow lens to take flat frames). We recommend our ASI1600/ASI174 mono camera for Ha solar imaging.

10Bit ADC

5496×3672 19fps
3840×2160 41.04fps
1920×1080 80.10fps
1280×720 117.30fps

12bit ADC

5496×3672 19fps
3840×2160 36.12fps
1920×1080 70.48fps
1280×720 103.23fps

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.
