Introducing the ASI183MC, ZWO’s most sensitive camera to date with a peak absolute Q.E. of 84% in mono made possible by a back illuminated sensor.

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

The 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 pixels.  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.

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.
