Just to add to this, although it is a perfect example of preaching to
a choir as I can think of. Its more than just the light pollution, as
it that weren't bad enough. On top of the sad reality that more than
half of the 7 billion plus humans on the planet will live their lives
having never even see the Milky Way, it is just as bad a travesty
because of the wasted energy of billions upon billions of watts of
lightbulbs doing nothing to make anyone safer, illuminating nothing
but the underside of aircraft along with the dust and water vapor and
gas molecules. And the solution is totally simple and achievable
right now, it isn't like we need to wait until the invention of cold
fusion or the discover of the Higgs particle. All it takes is for
everyone to just use correctly designed efficient outdoor light
fixtures that are available today and are relatively inexpensive. So
inexpensive that the energy saving over the life of the appliance
pretty much pays for it. As Richard says, there are so few of us that
object that its probably a lost cause anyway.

The sore lack of a star filled sky to spark the imaginations of the
next generations is a travesty to humanity.

Stan,
The fight against light pollution should have little to do with how
much faint detail can be pulled out of images. It should have
everything to do with the average Joe or Jill looking up, and not
being able to see more than
30 stars in the sky. It's everybody's fight, not just ours.
And regarding the great images, they would be three magnitudes greater
were it not for light pollution.
