 Subject: CCD imagery

Does anyone in this group own a CCD camera?  If you do, how would you like
to use it to participate in a unique data collection campaign to help map
Light Pollution around the world?  Please see the following page:


Establishing baseline data will help to provide documentation of the
improving or degrading conditions for your area.  It takes no genius to
look at the satellite photos taken a mere 8 years ago and compare it to
last year's images to see how fast the night sky around the world is
loosing ground to obtrusive outdoor lighting.
