Anti-fog system for Camera
The mist can settle on your sensor's protective glass and even freeze in the case of negative temperatures. In order not to interfere with your imaging session, ZWO offers a clever anti-fog device which is positioned as close as possible to the sensor, directly between the camera and your instrument (or corrector/filter wheel/optical splitter). The thickness of the ZWO anti-fog system is very thin and light (0.2~0.3mm) and works under a 12V power supply at 0.35A (so that the power is about 4.2 watts on the heating band).
It is also possible thanks to the special "Y" adapter (included) to supply the heating resistance ZWO and the cooling of the camera at the same time.
