6.3 Cooling system

The cooled ASI174 cameras have a robust, regulated cooling system, which means that the camera
sensor can be kept at the desired temperature throughout your imaging session. The super low
readout noise, combined with efficient cooling and adjustable gain setting, allows you to do short
or lucky DSO imaging unlike the traditional CCD cameras which need very long exposures for
each frame. However, keep in mind that cooling won't help with very short exposures such as less
than 100ms. The lowest temperature that can be set is -40℃.

6.4 Protect Window

There is an IR-CUT protect window in the ZWO ASI174MC and ASI174MC-C camera to prevent
the sensor from humidity and dust.
Diameter is 25mm and 1.1mm thick (non-cooled version),
Diameter is 25mm and 3mm thick(cooled version ).
