ZWO Camera ASI 183 MM


The ASI183 camera series represents the most sensitive set of cameras ZWO has ever offered. For such a small pixel size (2.4 µm), these cameras have a very large full well capacity (15000e), as well as 1.6e read noise @ 30db, and 12 stops dynamic range @ gain=0. The ASI183MM uses an extremely sensitive back-illuminated Sony IMX183CLK-J CMOS sensor with 20.18 MP effective pixels. It also makes use of firmware components to reduce amplifier glow for peak astrophotography performance.

High Speed

Fast FPS is beneficial for both solar and lunar imaging, along with live viewing/EAA. In addition, high speed readout may be used for real-time focusing, real lucky imaging of small objects like double stars, planetary imaging of the solar system's major planets, and much more.

10-Bit ADC

  • 5496 x 3672 - 19 fps
  • 3840 x 2160 - 41.04 fps
  • 1920 x 1080 - 80.10 fps
  • 1280 x 720 - 117.30 fps

12-Bit ADC

  • 5496 x 3672 - 19 fps
  • 3840 x 2160 - 36.12 fps
  • 1920 x 1080 - 70.48 fps
  • 1280 x 720 - 103.23 fps

High QE

Since it features a monochrome sensor with Sony back-illuminated Exmor R technology, the ASI183MM Monochrome Camera offers superb performance for deep sky applications. Peak QE for ASI183 cameras reaches an impressive 84%! QE remains at over 60%, even in the H-Alpha channel. With a high QE, a greater amount of light that enters your telescope and makes it to the sensor is actually used. An 84% peak QE and no less than approximately 50% within the visible spectrum enhances signal quality by allowing the ASI183 to utilize a higher percentage of light that reaches it.

USB 3.0 and ST4 Ports

USB 3.0 Port: Offers a bandwidth of 5 gb to allow full resolution operation at 19 fps in normal 12bit mode, or 19 fps in high speed 10bit mode.

ST4 Port: Enables guiding by connecting to a mount's auto guide port.

ASIair Pro Camera Control (sold separately)

There is a wireless camera control solution available for this camera, and it's called the ZWO ASIair Pro. This small wireless module allows you to focus, take images, make adjustments with your smartphone or tablet, and even do plate solving and computerized mount control with the built-in SkySafari bridge. If you'd like to add an ASIair Pro to your camera order, you can find it in the suggested accessories section.
