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

Astrophotography Performance

The ASI183 camera has 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 also utilizes 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.

High QE

Sony’s back-illuminated Exmor R technology gives excellent deep sky performance. The ASI183 QE peak reaches a remarkable 84%. In the Ha channel, QE is 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: This port provides 5Gb bandwidth to make it possible for the ASI183 to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution (20.18 megapixels).

ST4 Port: Connect with your mount's auto guide port
