The new ZWO ASI183 has lots of astro photo potential with its 84% QE peak, 20.18Mega pixels resolution, 15000e full well, 1.6e read noise, 19FPS at full resolution. Each feature means a new posibility!
Although comes with some similar features, don't be confused, this is not to replace the already well established ASI1600 series; read the below article to get a better understanding of its main area of "expertise" and see if it is the ASI183 or ASI1600 that would fit your telescope setup better. Shortly, this camera would very well fit small, fast ED doublet or triplet apochromats, achromates and small, fast Newtonian telescopes.
Introducing the ASI183 camera series, the most sensitivie cameras in ZWO history. Peak Q.E. of the mono sensor reaches 84%!
Diagonal size 15.86 mm, approx. 20.48M effective Pixel count (available with Monochrome or Color CMOS Image Sensor)
High-Speed and High-Picture-Quality Rolling Shutter-Type Back-Illuminated CMOS Image Sensors
In the astronomic application field, the Sony IMX183CLK-J (monochrome) and IMX183CQJ-J (color) sensors use a very high sensitivity back-illuminated structure with high resolution 2.4 _¦m square unit pixel.
Astrophotography PerformanceThe 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.

3840x2160 36.12fps
1920x1080 70.48fps
1280x720 103.23fps
High Quantum Efficiency
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.
Dark Current
The dark current of the ASI183 is extremely low, based on our test results.
USB 3.0 Port & ST4 Port
USB 3.0 Port: Provides 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). (Bear in mind, you'll need large storage capacity on your computer as a video at this resolution will create a very large file...
ST4 Port: Can be used to connect with auto guide port of mount, for guiding. (Due to the comparatively large size of the chip, this function would be rarely used, unless this camera is used as a guide camera on a system with a really large telescope next to it....)
What is in the box?
The ASI183 box includes all necessary cables, adapters, and manuals.
