Product Description
ASI183 has much potential, 84% QE peak, 20.18Mega pixels, 15000e full well, 1.6e read noise, 19FPS@full resolution, each feature means a new possibility!
Introducing 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 astronomic application field, Sony IMX183CLK-J (monochrome) and IMX183CQJ-J (colour) sensors uses 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 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.
High Speed
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, true lucky imaging of double stars and other small objects, planetary imaging of the major planets in the solar system, and much more.
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, 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.
USB 3.0 Port & ST4 Port
USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI183 to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution(20.18Mega).
ST4 Port: Can be used connect with auto guide port of mount, for guiding.

Customer Reviews
Very sensitive. Low noise for an un-cooled camera, Tested on the moon and bubble nebula. Results were better than expected . Excellent camera at the price point. Works well with the ASIair Plus. The bubble nebula was taken using a sky glow filter, not narrowband. (9.25 SCT @ f6.3) 35 - 1 minute exposures.
