Product Description
Camera Sensor
Our popular ASI174MM CMOS Monochrome Imaging Camera is based on the Sony Exmor IMX174 2.35MP sensor with Pregius global shutter technology.
▶Sony IMX174 CMOS Sensor Features
- The Sony IMX174 monochrome CMOS sensor separates the ASI174MM from previous ASI models. This type 1/1.2” Sony CMOS image sensor features a 1936 x 1216 array with, 5.86µm pixels in it. It has a lot of advantages when taking high quality solar, lunar, planetary, and deep sky object images.
- Pregius Global Shutter function with analog memory permits the scanning of all pixels simultaneously. The Sony IMX174’s global shutter function provides improved 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.

Mike – :
Considering this for planetary imaging. However, I have an old MacBook Pro that works quite well & that I’ve upgraded to a 1TB SSD, but it only has USB2. Would the 174mm still have a higher frame rate than the 174mm mini or should I just get the 174mm mini?
Thanks.

Charline – :
Hi!
I bought the 174MM USB3 to do some high-speed imaging, unfortunately, the highest speed allowed at Raw16 is around 66 FPS in full-frame format, and not 128 as mentioned on the specifications. I use it on ASICap (last version) with the high-speed mode ON, USB traffic is 90%. How can I fix this issue to be able to work with this camera at its full capability?
Thanks.

Hi,
I’ m using the ASI174MM for H-alpha imaging of the Sun.
Unfortunately, the stacked images show fine horizontal stripes in the images.
I used firecapture to process the darks while imaging, but it didn’t seem to have any effect.
I would prefer to process the flats, but should I use the flats on a regular telescope? Also, does firecapture have the ability to save and load flat images?
In my case, I am imaging with the LS80THa/B1800 solar telescope in direct focus and the PowermateX2.5.

You call this camera “Brand New” and include both MM/MC. All your other cameras are either MM or MC. How new is this camera and is this camera a combination of Mono and Color?
0

Support@ZWO – :
It is mono and we call this “Brand New” because it is only one which uses global shutter.

You can use 1.25″ nose piece to connect your telescope and ASI174MM camera instead of eyepiece.

Hi,
some years ago (2017-2018) i have acquired the ASI174mono. I have a doubt about the sensor (Exmor IMX174) and the global shutter technology. Looking on website, i read these characteristics. My camera has the same features or an updated has been done?
Thanks

Hi, I am currently using the 178MM but looking to change to the 174MM with a Takahashi FC-76DCU at f/7.82 as this gives me the full disc of the moon. Should I still use a IR pass filter when imaging the moon ? If I use it for solar imaging in white light OR with a Quark would I need to use a UV/IR ? Thanks.
0
0
Katherine Tsai – :
It does not need IR cut when you shoot the moon, you do not need UV/IR cut if you use Quark.

I am looking at the ASI174MM for eclipse photography. Is there a way to attach this camera to a Canon EOS lens? Also, how does the sencer size compare to a full frame camera? Also, given the 2.3 mega pixels how much image enlargement is possible?

Sean Wang – :
Yes, we have two adapters for EOS lens. one is directly work with lens.

one is work with EFW together with lens.
