ZWO ASI174MM-COOL USB3.0 COOLED Monochrome CMOS Camera
Price:  £934.00(Inc. 20% VAT)

Product Code:  ZWO-ASI174MM-COOL
Manufacturer:  ZWO
Cooled or Uncooled:  Cooled
Resolution:  1936 x 1216
Pixel Size:  5.86µm
Sensor Size:  1"


Our brand new COOLED version of the ZWO ASI174MM mono CMOS Imaging Camera  allows the sensor to be cooled to 35 - 40 degrees C below ambient temperature!

The  1″ sensor size and 5.86 pixel size of the ZWO ASI174 makes it very suitable for long exposure DSO imaging for most telescope.

The high Quantum Efficiency, low read noise and super fast speed of the ASI174 makes this camera a very versatile one that can be used as a planetary imaging, solar imaging (with the necessary front solar filter, of course), lunar imaging and even a very capable deep sky imaging camera. This unsurplussed versatility makes it a very good alternative to more expensive deep sky imagers or planetary imagers.

This camera will mostly be used for imaging the Sun and the Moon with smaller telescopes or even planets with larger telescopes with long focal length, plus now that it comes with active cooling, it can also be used very well for deep sky imaging  up to 1000 seconds exposure time.

With this monochrome version, you'll also need a filter wheel and a set of L-RGB filters or H-alpha and OIII filters, and maybe even H-beta and SII filters as well for narrow band astro photography...

Features of the ZWO ASI174MM COOLED Camera

  • Recommended for the Sun, Moon, planets and deep sky objects
  • (To image the Sun you'll have to use a proper front solar filter or Herschel wedge depending on your telescope type. Please contact us if not sure!)
  • Resolution: 1936X1216 at up to 164fps (at 12bit ADC) or 128fps (at 10 bit ADC)
