The ZWO ASI183MM is the most sensitive ZWO camera currently available. What a great piece of gear for planetary deep space imaging!
The ZWO ASI183MM is a special camera at a very affordable price. It is the most sensitive camera that ZWO produces (as of 2020) and is extremely fast. The back-illuminated Sony IMX183CLK-J sensor is capable of producing planetary, solar, Live Viewing/EAA and deep space.
The 20.48 megapixel CMOS sensor is capable of recording 19 frames per second in full resolution. You can get all the way to 308.17 frames per second at 320x240 which is excellent for planetary imaging.
High-Speed and High-Picture-Quality Rolling Shutter-Type Back-Illuminated CMOS Image Sensors
The pixels of the 1" diagonal Sony chip are quite small at 2.4 μm square, but they have an astounding well depth of 15,000e. The 12 stop dynamic range is further assisted by firmware to help the back-lit chip minimize amplier glow for maximum imaging performance.
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 a 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.
The ZWO ASI83MM conectivity.
USB 3.0 Port: Provides 5Gb bandwidth to make it possible for ASI294MC to run at 16fps (14bit, normal mode) or 19fps (12bit, high speed mode) at full resolution (11.7Mega).
ST4 Port: Can be used to connect to the auto-guiding port of your mount and become a great guider.
ZWO has all their information available for download on their website in a perfectly laid out section. Check it out here for software and drivers and here for manuals and guides.
One of the coolest gadgets, and a neccessity according to a majority of ZWO users, is the ASIair Plus. It is an all-in-one wireless camera solution. The ASIair Plus gives you control of focus, image taking, plate solving, and computerized mount control with the included SkySafari bridge all controlled by your smartdevice or tablet. It really is pretty awesome.
