Product Description
ASI183MC Pro
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.
Reliable 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.
Dark frame sample @ Highest dynamic range settings(gain=0), 300s, -10°C, bin1. Please check the dark frame to make sure you are fully know the performance.
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).
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.
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.
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.

J.L.BROADSTONE – :
I am using a Skywatcher Evostar ed80 along with a Skywatcher field flattener which needs 55mm backfocus, an ASI183MC which needs 55mm backfocus, and an IR/UV cutoff filter. What spacing is needed? 55mm, 56, 54mm or something altogether different? Thanks.

It needs 55mm backfocus.And it depends on telescope, instead of the camera.

I’m planing to buy the ASI183MC PRO. Which parts do I need to ensure the right back focus distance with EF lenses. I will use EF 200 L f2.8 II and EF 400 L f5.6. I will also buy the ZWO OAG becasue the guidecam will be in center with the lens for better balance on the mount. Which other adapters do I need? Should I use 2″ or can I live with 1,25″ filters on the 1″ chipsize? Thanks for your anwser in advance.

Katherine Tsai – :
For 183, 1.25 inch filter is enough.
Before you use OAG, please make sure the light path to the OAG would not be covered by the edge of the lens.
183MC pro provides 6.5mm +T2 ring(11mm)+OAG(16.5mm), you will need another 10mm extension tube.

Hi,
I’m new to AP. Have ordered sw 80mm ed, and sw HEQ5 goto mount. I saw the split issues from 183mc pro @ https://www.youtube.com/watch?v=GPq658dNYs4. The user returned the camera and upgraded to 1600 pro. Please share if the split issue has been resolved or was it a one off issue with a particular user.

Hi ZWO Team,
I am thinking of buying a 183MC for my Newton 200/100 PDS to get pictures of smaller DSO, like M57 with higher resolution? Is this a good choice or is another cam recommended.

Hi, I’m using this camera with ASIAIR. When I preview the picture on my iPad, it shows color picture. However, saved FIT files in SD card are all 16bit gray-scale images. How can I save pictures as color FIT file? I also tried to take picture on ASICAP application on my Mac with this camera. The preview image on this application is always color image, but when I save it as 16bit, saved FIT files are gray-scale as same as ASIAIR does.

Hi there. RAW data is gary, ususally we will debayer it in post-processing. If you would like color images, in ASICAP, don’t click “raw data” box, and choose RAW8, you will get color images. But in ASIAIR, the data must be saved as original RAW data. you can use the SAVE button on the buttom-right to save a JPG in your iPad.

Hi. I bought this camera a month ago and have not been happy with it. I was struggling with very bloated stars and spent a lot of time trying to fix focusing problems with DSLR lenses, thinking that was the problem. I was told by someone on an internet forum yesterday that it is most likely because this model camera does not have a UV / IR cut filter. This might also explain the poor colours I get in my images. So I understand I have 3 options to fix this issue. 1- replace the AR window covering the sensor with a UV-IR window. This seems like the best option but I dont see one listed for the ASI183MC Pro. Option 2 is to buy a 1.25″ UV-IR filter and mount it between the camera and the EOS-T2 adapter. The problem with this option is that I think it will create too much distance between the camera flange and the sensor (unless I buy the thinner EOS-T2 for the EFW and also a spacer ring). Option 3 is to buy a 77mm UV-IR cut filter for the front of my camera lenses. Fortunately the one 77mm filter will work on the two lenses I would be using with this camera. Can you please advise ASAP which of these the options is best and will fix this problem for me as quickly as possible. Thanks.

Sean Wang – :
Hi Kelvin
I think the option 2 is best, the EOS-T2 can hold a 2″ filter inside it.

Hello, I bought this camera and a trial survey found on the matrix a large speck of dust. Can I remove the cover over the matrix and clean the matrix without losing the warranty? Or I’m in Russia and guarantee I don’t get anyway?) Because I didn’t find the coupon anyway…(

Thanks for the information Sean! How about between the ASI183MC and the ASI294MC for EAA and DSO Astrophotography?
0

Sean Wang – :
ASI294 is better for EAA. it not only has bigger sensor, but also has HCG mode(have high dynamic range under 120 gain).

Jeremy Morgan – :
Would this camera (ASI183 Pro) be a good match for the Stellarvue SV80 Access F/7 APO Refractor? Or would the ASI385MC COOL be a better match? I am mainly interested in EAA and DSO Astrophotography.
0

Sean Wang – :
Hi Jeremy
I think ASI183 will be better than 385. because 183 have bigger FOV and higher resolution. Thoes are very important for DSO imaging with small telescopes.
In EAA, bin2 mode will improve brightness of target, after bin2, 183 still have nearly 5 mega pixels.
