About this product

Model:  zwo_asi174mm
Part Number:  ZWO ASI174MM

The ZWO ASI174MM Mono imaging camera features Sony's Exmor IMX174 2.35MP CMOS sensor with Pregius global shutter technology is an excellent choice for lunar, planetary and solar imaging! 

"This is a fantastic all-round camera capable of imaging Solar System objects as well as deep-sky targets. Its forte is producing spectacular, large-area captures of bright objects such as the Sun and Moon. Although other cameras from ZWO themselves, have encroached on this capability, the amazing frame rate offered by the ASI174MM makes it a first-class performer for this sort of application."  Pete Lawrence writing for 'BBC Sky at Night' magazine Aug 2015. 

The ZWO ASI174MM is such a good all-rounder it seems unfair to mention it’s one weakness: When used for deep sky imaging amp glow becomes apparent on one side of the frame and increases with longer exposure times. Dark frame subtraction can remove it but it isn’t ideal.

Deep sky imaging aside, the ASI174MM is a true diamond with nice large pixels that suit most telescopes and applications. 

Sony IMX174 CMOS Sensor Features

  • The Sony IMX174 Mono CMOS sensor separates the ASI174MM from previous ASI models. It's 1/1.2” sensor with 5.86µm pixels in a 1936 x 1216 array is very well suited to high quality solar, lunar, and planetary imaging.
  • Pregius Global Shutter function with analog memory scans all pixels simultaneously. The Sony IMX174’s global shutter function improves image quality by making sure images of moving objects avoid focal plane distortion. This is especially helpful when performing solar or lunar imaging. Bad seeing, wind, or movement can alter the image if the readout speed is not quick enough (< 30fps).
  • Sony Exmor technology uses column-parallel A/D conversion for high speed processing, low noise, and low power dissipation.
  • ROI, or Region of Interest Mode lets you capture up to 16 areas inside the effective pixels. This ability allows for even higher frame rates.
  • High speed imaging with a max of 164.5 fps at 10 bit ADC, and max of 128.2 fps at 12 bit ADC

ZWO ASI Camera Body

The ZWO ASI174MM Mono CMOS Camera seems like a natural progression from the ASI120MM-S. It comes with high speed USB 3.0 port, standard 2″ M42 x 0.75 internal thread interface, 0.25″ tripod thread mount on the rear, an AR window and an ST4 Guide Port. With the ST4 Guide Port, you can use 3rd party software, like Maxim LD or PHD, to guide your mount for longer exposures.

Dimensions of the aluminium body are 62mm x 36mm, or 2.44 inches in diameter by 1.41 inches deep, and it weighs only 4.2 ounces. 

All ZWO cameras include a 2-year warranty.

Good guiding camera
10 November 2023  | 

I got this to replace my ASI120MC-S which I used for guiding with a ZWO OAG. At shorter focal lengths that was fine but at 1000mm it really didn't see much even at gain 100 and bin2. This, on the other hand, had no problem seeing multiple guide stars without any binning. Very happy with it.

The only thing to watch if you want to use it as a guide camera is the back spacing. The 6.5mm spacing is to a male M42 connector which is no good for connecting directly to an OAG, the enclosed female-female M42 coupler adds 11mm of extra back spacing which was too much for me so I had to buy a smaller coupler elsewhere.

Expensive but worth it
26 July 2023  | 

I bought the ASI174MM as an upgrade to my Solar imaging camera on my Coronado. I’ve been waiting for an opportunity to test on the Sun, but the UK weather in July has been nothing short of awful. During a break in the clouds, I have tested it and found that the results are very promising. It produced a full disk image, and after tweaking a few settings, given the conditions on the day, have produced good results. I look forward to when a clear day offers good seeing conditions to fully test.

I have paired the ASI174MM with an Esprit and replaced my ASI120MM, and the new camera will be pressed into service for guiding. Last evening was an opportunity to test the camera as a guide camera, and I must admit it provides a great field of view and excellent results.

I have yet to test the camera on the Moon and the planets, that will come. But I believe from what I have seen thus far that it will deliver crisp images. So in summary, expensive, but worth the money.

ZWO-ASI174MM
19 June 2022  | 

I had been looking for a while, to upgrade the planetary camera that I brought in 2021. Whilst this is a good camera it has a narrow field of view due to the small sensor which isn't ideal when Solar imaging.
I wanted something better.

ZWO ASI 174MM USB 3 Mono camera was the obvious choice. It comes with smaller pixels and a nice big 1/1.2″ CMOS IMX174LLJ / IMX174LQJ sensor. This is ideal for imaging all the Planets, the Moon, and the Sun ether in white light or as I do. Through a Daystar Quark.

If you are looking for a good planetary camera then this beauty is for you.

Ideal for camera for solar, lunar and guide cam
21 January 2022  | 

This has proved to be the most problem free camera to use for solar imaging (large sensor size, global shutter). Similarly, quite a good camera for lunar. It's also been my favourite camera to use as a guide cam since the large sensor allows finding suitable guide stars and you can also use it to do plate solving and polar alignment. The only major negative is it has more amp glow than any camera I've ever tested. It's therefore not suitable for exposures longer than a few seconds and not recommended for deep-sky imaging or spectroscopy. But it's definitely a great all-round camera for a lot of other purposes.

Excellent lunar camera
17 January 2022  | 

I was recommended by the staff at FLO that this camera would work well with my 11" Edge mounted on my iOptron CEM70, I also control it via the AsiAir Plus. I did have a frisson of doubt as the pixel size is bigger than the 3.75 microns often recommended else where with the 11" Edge.

I had a good imaging session and the results were superb, I got detail and sharpness that really surprised me. The detail I got on the floor of Gassendi took my breath away.

Great camera for Lunar and Solar photography
05 August 2020  | 

I used this camera to get fantastic images of the moon. I also used it as autoguide camera for deep sky photography. It works great with StellarMate / Indi Server and KStars.
