QHY-8 PRO 6 MPixel Cooled One Shot Color Camera
               ALL QHY-8 Pros now come with a window heater ring to stop any humidity issues during high humidity nights.
I have modified the heater ring so it connects and disconnects easily using standard DC 2.1mm plugs, and so use your existing camera power supply without
modifications.
Easy, neat, and quick and so simple.
Note: Modified heater rings (2.1mm DC Jack) are only available from
here (Gama Electronics).
Therefore, other dealers may or may not have a similar setup.
