    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.

      ZWO ASI183MM Pro Astrophotography Camera

      I've had the camera for two weeks now, along with a number of clear nights. The images it produces are clear and detailed and I am thoroughly enjoying this new addition to my astrophotography rig. It pairs very nicely with my William Optics RedCat 51.

      ASI183MM/MC Pro

      I've been using both the MM and MC versions of the ASI183 Pro camera with two fast (f/4.7) scopes and the image scale with this 2.4µm pixel size is a perfect match up for them or any focal length around 300mm - 500mm. To me, the sensor' only shortfall is the relatively shallow well depth but that can easily be compensated for by controlling exposure length. Some folks may take pause at some of this sensor' specs (compared to say the 6200 or 2600) but with attention to sub calibration those concerns are a moot point. Also, I mainly image DSOs but have begun doing some solar and planetary work with this camera and while not as speedy as the ASI290 or ASI462 I am finding that the IMX183 sensor performs very well making this camera truly multifunctional.

      Zwo 183mm oro cooled camera

      This is the best camera I have ever used. This camera is far superior to the asi 2600mm. My exposures are cut down to 3x5min each channel with great results.

      So sweet!

      I was finally able to get clear skies after all the new gear arrived and it works great! This camera is really good and I am enjoying the new challenge of capturing data with multiple filters. Don't be turned off by the amp glow it processes right out with propper Darks, Lights, and Bias files. Looking forward to the Nebula as Galaxies are a little small in my FOV with my RedCat. Or maybe it's time I buy a bigger scope lol I am sure OPT will like that :D

      An excellent camera for the money. I got this to fill a dual purpose of planetary and deep-sky and it does the job. Calibration will be difficult, even with a full set of frames the amp glow pattern is still partially visible if an image is stretched very hard.
