ZWO’s Versatile and Sensitive Astronomy Camera

The ZWO ASI183MM is a versatile and highly sensitive monochrome astronomy camera for deep-sky imaging, lunar and solar imaging, and electronically-assisted astronomy (EAA). The camera incorporates a large state-of-the-art 13.2mmx8.8mm CMOS sensor with high quantum efficiency to help you extract maximum detail in your astrophotos while keeping noise and exposure time as low as possible.

High-Quantum-Efficiency CMOS Sensor

The ZWO ASI183MM-Pro monochrome camera uses a 20.1 megapixel 5496x3672 Sony IMX183 CMOS sensor. Thanks to an innovative photodiode structure and on-chip lenses, the monochrome version of this back-illuminated sensor provides a peak quantum efficiency as high as 84%. Even at the hydrogen-alpha wavelength of 656nm, the QE is over 60%.  The full well capacity of the 2.4 micron pixels is 15,000e, while read noise is a low 1.6e at 30dB gain. The low noise and high efficiency of this sensor allow you to capture more light with less noise for a given exposure time. The ASI183MM-Pro also includes advanced firmware to reduce amp glow in the camera.

Fast Data Transfer

The USB3.0 port of the ASI183MM offers a fast 19 fps capture rate at the full resolution of 5496x3672 with 12-bit ADC, and much faster rates at lower resolutions. These data rates are perfect for solar and lunar imaging, and they allow for real-time focusing during EAA and imaging applications. This camera is also great for ‘lucky imaging’ of planets, double stars, and other compact objects, especially for telescopes with longer focal ratio.

Ready to Go Out of the Box

The ASI183MM includes everything you need to get started including a ST4 cable, 1.25” cover, T2-1.25” adapter, 2” cover, 1.25” nosepiece, and USB3.0 cable. The camera also incorporates an ST4 port for autoguiding and an AR-coated window to protect the sensor.

This camera can be configured with the following connections for attachment to telescopes and imaging accessories:

  • 1.25” nosepiece
  • 2” nosepiece (optional 2” extension strongly recommended)
  • Female T/T2 thread (M42x0.75)
  • Male T/T2 thread (M42x0.75)
  • Female M28.5x0.6 thread via 1.25" nosepiece or T2-1.25" adapter

The ASI183MM is just 62mm in diameter and weighs 120g (4.2oz).

ZWO is phasing out software CDs, but the camera comes with instructions to help you download the required control software and drivers directly from the ZWO website.
