Our brand new COOLED version of the ZWO ASI174MC Colour 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.

Here you can read an interesting review on the Cloudy Night forum.

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. This colour version is recommended for one shot narrow band deep sky photography if you don't want or cannot spend too much time with imaging, but if you want to get out the best data from your camera and achieve even sharper, contrasty deep sky, solar or lunar images, we'd recommend you to choose the monochrome version, the COOLED ZWO ASI174MM.

With this colour version, you'd not need any filters or filter wheel.
