About this product

Model:  zwo_asi174mm-cool
Part Number:  ASI174MM-COOL

New cooled version of ASI174MM Mono 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. 

Anti-reflective (AR) optical window. 

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. 

All ZWO cameras include a 2-year warranty.
