Dear all, I'm experiencing humidity problems inside the acrylic dome, even if the heater is on. IMO there are two possible problems: the heater is not working anymore, or humidity enters from below the camera, inside the acrylic dome. Is there anyone who has experienced the same problem? Is thre a way to know if the heater is working? Thank you and best regards, Luca Buzzi Schiaparelli Astronomical Observatory MPC 204 - Italy
