ZWO ASI 183 Pro Cooled Monochrome CMOS Telescope Camera

The ZWO ASI183MM Pro Cooled Monochrome CMOS Telescope Camera helps you see deep space in high-contrast. Engineered with a peak Q.E. of 84%, and optimum cooling to 45-degrees C below ambient temperature, capture stunning details of planetary and deep space objects.

The ASI183MM Pro Camera Specs at a Glance


Planetary and Solar Imaging

Save time with the ASI183 Monochrome! It can record full 20.2 MP videos at 19 frames per second and capture the entire sun with its 1350 mm focal length. If you enjoy speed shooting planets like Jupiter and Saturn, the ASI183 clocks out at 308.17 frames per second at 320 x 240 resolution!


Sony IMX183CLK-J CMOS Sensor

Offering a higher resolution, high Q.E., and efficient signal-to-noise ratio, the sensor is approximately 15.9 mm, and is back-illuminated for higher Q.E.! It can record 20.2-megapixel videos at 19 frames per second, which is 48% more resolution than an ultra, high-definition 4k video!

The Sony CMOS sensor offers 12 stops of dynamic range, giving you fuller images! When the gain settings are at 0, the read noise reaches 3e, and when the gain settings are at 30, it offers a low read noise of 1.6e.

USB 3.0 Port & USB 2.0 HUB

Get faster transmission with the USB 3.0 providing 5 GB to allow the ASI183MM to run at 19 fps. Get more from your camera by connecting to different accessories while having better cable management.


High Quantum Efficiency

Capture high-contrast images with the ZWO ASI183 camera's incredible light-gathering ability. The ZWO ASI183 has a peak Q.E. of 84%! Also, the H-alpha emission line is recorded at 60% and doesn't record less than 50% in the visible spectrum.

High-Speed Video Recording

Focus in real-time and get the most data for your solar and planetary imaging setups with a 1-inch optical. The ASI 183 uses a high sensitivity back-illuminated structure with a high resolution of 2.4 μm square unit pixel. See how it compares at different rates below.

      A great camera

      I love this camera. So far I've done a few projects and the resolution is amazing. It's very sensitive too. I use narrowband filters to block light pollution with exposures in the 240s to 300s range. There is serious amp glow, but I've calibrated it out.

      Thanks ZWO

      The quality camera for this price.

      Wonderful once you solve amp glow

      I’d heard of this issue but was shocked when it hit...yikes. But some excellent advice from ZWO to make sure you calibrate with a master dark exactly set to the same gain as your light, and without optimizing or using bias frames [PixInsight] and it goes away. Phew... Shooting at Unity Gain, 111 for this camera.

      ZWO ASI 183 Pro mono cooled

      OPT same-day shipped the 183 pro and it arrived 2 days later via USPS. I bench tested the camera and it appeared to be working correctly. However, be advised that this relatively new CMOS camera requires the latest drivers from the ZWO website be installed. This includes both the ASI_camera_driver and the ASI_camera_ascom driver for Windows 10. I found that both SGP 3.03 and Sharpcap 3.2 will run this camera with the updated drivers.

      Terrific camera, great OPT ordering

      The camera is perfect for high-resolution imaging with shorter focal-length setups, such as my William Optics Z61. Everything worked right out of the box, cooler gets to -20C without breaking a sweat, and the low-noise images that result are detailed and easy to stack. What little amp-glow there is calibrates out with dark frames with no problem. Looking forward to doing narrow-band imaging with it soon! Typical good OPT ordering experience: ordered on Wednesday, had it on Thursday.

      Great camera

      This is my first dedicated astro-camera, used DSLRs previously. Easy to set up and use, all necessary adapters and cables were included with the camera. Seamless interface to guiding camera (ASI290MM Mini) and filter wheel (EFW8), simplifies cabling with built-in hub. Excellent results so far with my 73mm APO.
