Product Description

ASI183MM Pro

183MM Pro1


Introducing the ASI183 camera series, the most sensitivie cameras in ZWO history. Peak Q.E. of the mono sensor reaches 84%!

Diagonal 15.86 mm Approx. 20.48M-Effective Pixel Monochrome/Color CMOS Image Sensor


▶High-Speed and High-Picture-Quality Rolling Shutter-Type Back-Illuminated CMOS Image Sensors

In the astronomic application field, Sony IMX183CLK-J (monochrome) and IMX183CQJ-J (color) sensors uses a very high sensitivity back-illuminated structure with high resolution 2.4 μm square unit pixel.  The optical size is 1 inch.

DDR Memory Buffer

The ASI183 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.


DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

Astrophotography Performance

The ASI183 cameras has a very large full well capacity(15000e) for such small pixel size, 1.6e read noise @ 30DB, and 12stops dynamic range @ Gain=0. The ASI183 cameras also utilize firmware features to minimize amplifier glow for maximum performance in astrophotography.

183 Gain RN DR FW vs gainReliable Mechanics

ASI183 Pro has same mechanics as ASI1600 Pro. There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable.

Even when used in higher humidity environments, ASI183 Pro will still work fine without dew problems.

High Speed

Fast FPS can be used in solar and lunar imaging, as well as for live viewing/EAA.The high speed readout may also be used for real-time focusing, true lucky imaging of double stars and other small objects, planetary imaging of the major planets in the solar system, and much more.

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 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.


Dark Current

The dark current of the ASI183 is extremely low, based on our test results.


USB 3.0 Port & USB2.0 HUB

USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI183 Pro to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode)  at full resolution(20.18Mega).

Recommended cooler power supply: 12V @ 3-5A (or more) DC adapter (2.1×5.5mm, center pole positive). Also suitable: DC battery with 9-15V.

Using a battery with 9-15V is also suitable for the cooler power supply.

USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can better manage your cables. The ASI183 Pro includes two short 0.5m USB 2.0 cables. The integrated USB 2.0 hub is powered by the external power source if you connect one.

183MM Pro2

Cooling System

The ASI183 Pro has a 2-stage TEC cooling system that enables deep cooling (40°C-45°C below ambient). The cooler requires an external power supply, which is not included with the camera. You may order a suitable power supply from here.

    Hello. Is it support 4k video out like qhy 183 mono? Very like your product.

    • Sam Wen


      of couse, 4K is under ROI mode

  3. (verified owner):

    I have a celestron c8 in avx mount. Is this camera will works well for me? Deepsky…planets. thanks

    • Sam Wen


      yes, you can shoot for planets for direct focus
      and you can bin for deepsky

  4. :

    Will you offer the camera with the 8pos filter wheel kit? I purchased my 1600 with it and I would like to repeat.

    Thanks Sam!

    • Sam Wen


      we will make such combination in the future
      thank you

  5. :

    Will the183 Pro be offered with a heated window? No need to add heating rings.

    Thanks, Sam.

    • Sean Wang


      We improved the mechnics, camera body will be heat by TEC, protective window too.

  6. :

    For my first monochrome Deep Space Camera would you recommend this camera over the 1600?

    • Sean Wang


      Hi. 1600 has bigger sensor size, 183 has higher sensitivity, I can’t say which one is better, they have different advantages.
      If your telescope is small and focus length is short, 183 will be a good choise.

  7. :

    Hi, can you offer a dark frame with 300 s for this new camera?

  8. (verified owner):

    Hello. How to charge this camera from the car charger? Thanks

    • Sean Wang


      Looks good, However, we didin’t use it before.

  10. (verified owner):

    What size of filters do you recomend for this camera…1.25″ or 36mm? Thanks

    • Sean Wang


      Happy new year! We just back on work now. Sorry for late reply.
      1.25″ filters is big enough for 183 camera.

  11. :

    Hi Sam
    Could you let me know the relative sensitivity of the 183MM mono and the 178MM mono sensor, the 178 is much smaller overall of course but the pixels look to be the same size and so do they have the same absolute QE and sensitivity?
    Many thanks

    • Sean Wang


      183 absolute QE is 84%,178 we don’t have a exactly data. But, we suppose that sensitivity of 178 is lower than 183.

  12. :

    I notice this is on back order. When will it be available? Also, will the Baader 1.25″ IR cut filter work with this camera. Or would it be better to purchase the ZWO cut filter? Thanks.

    • Sean Wang


      Available time will be end of March possibly. Baader 1.25 filter is suitable.
