Help needed for SBIG fogging issues.
I've had some problems with my new ST-7XME fogging up. This has been a problem from the first time I used it. The suggestion put to me on the forum here was that my desiccant needed recharging. I felt that this was strange as this is a brand new camera and I would have thought that they would have come out with a charged desicant plug.
To cut this short, I charged the plug tonight, 4 hours at 180° C, reinstalled the plug, waited an hour and a half for it to soak up any humidity in the chamber and cranked up the camera. I set the temp to -15° and let it sit for half an hour. Sure enough the glass screen fogged over.
How long should I need to wait to expect the desiccant to work. The manual says "Expect the camera to take an hour or two to reach the frost free state". They don't actually say if the camera needs to be running or not, though I am assuming that the desiccant is like Silica Gel and just absorbs moisture from the enclosed environment.
