New cooled version of ASI174MC Colour CMOS Imaging Camera enables sensor cooling to 35-40C degrees below ambient!

The 1″ sensor and 5.86 pixel size is well suited to deep-sky imaging. 

The cooler requires a 12v power supply at 2.5A or 3A max DC adapter.

The camera can be used without the external power supply but will run in the normal, uncooled mode. 

Note: Photo showing rear of camera is from the MM model - the layout is identical.
