As long-time viewers of my Eyes on the Sky videos know, I am a big advocate of reducing light pollution. And as I've read up more on not only tent camping (star parties, here I come!), but even doing some backpacking/camping, I've discovered the Leave No Trace principles. To me, that's another facet of conservation that I've discovered - leave things as they were (or better) then how you found them. Conservation covers much more than that though: Preserve, protect and restore a natural environment as much as possible. 

I think light should be a part of that discussion too, but it almost never is.

Conservation encompasses many things, but I am often surprised how few people that are heavily involved in conservation know about light pollution, or for that matter, the powerful effects of even small amounts of light. It's not that they don't care; it's more often that they don't even know. 

Very often those...

Have you ever driven down the road at night, and had an oncoming driver be completely oblivious to the fact that they have their high bean headlights turned on? You flash at them, they ignore you... and so you squint, perhaps slow down, and look to the side of the road away from the lights, hoping you don't hit the approaching vehicle. 

And yet, in communities across the United States (and many across the world), we routinely put up with similar lighting situations. Lamp posts with lights that go every-which-way, porch lights that blast light everywhere including out into the street, and perhaps worst of all, floodlights that are mis-aimed and can actually blind drivers who are subjected to them.

The Nightlight

This blog includes what to see in the night and daytime skies, thoughts on telescopes, binoculars, and other astronomy observing accessories and equipment, plus my own occasional notes on objects I've seen and observed. Oh, and the random theater or other "my take on life" post. In other words, there is always something interesting. Check it out.
