The ASI183MC is ZWO's most sensitive camera to date which is made possible due to a back iluminated sensor. It comes with a IMX183CLK-J/CQJ-J sensor. It has a diagonal of 15.86 mm and an approximately 20.48M-Effective Pixel Monochrome/Color CMOS Image Sensor
High-Speed and High-Picture-Quality Rolling Shutter-Type Back-Illuminated CMOS Image Sensors:
The ASI183 uses Sony's IMX183CLK-J (monochrome) and IMX183CQJ-J (color) sensors which has a very high sensitivity back-illuminated structure with high resolution 2.4 μm square unit pixel. The optical size is 1 inch.
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 amp-glow for maximum performance in astrophotography
The camera's fast FPS is ideal for both solar (white light) and lunar imaging. as well as for live viewing/EAA (electronically assisted astronomy).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.
*Note: Some users find that this IMX183 sensor might have some grid pattern noise when do Ha solar imaging, hence please take the flat frame for calibration(add a barlow lens to take flat frames). We recommend the ASI1600/ASI174 mono camera for Ha solar imaging.
The camera uses 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%.
A high QE means that the majority of the light that enters your telescope and reaches the sensor is actually used. With 84% peak Q.E. and no less than approximately 50% within the visible spectrum, the ASI183 will utilize a high percentage of the light that reaches it, significantly 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.
