Re: CCD Clear Sky Detector Sees Clouds

About as bright as they come in the far IR.
Look at the IRAS maps to see what the sky looks like at your resolution.
   As I suggested, such cloud detectors work well with
certain types of clouds; I bet there is a huge difference
between cirrus and cumulus for example.  Sounds like you
have some experimentation to do!
