Orion in the Seattle skyglow

Submitted by jimwcoleman

This is a 4.5 minute (9 30-second subs, stacked, ISO 1600, f5.6) exposure of Orion. You can clearly see the Flame Nebula and M42, the Great Orion Nebula. The fir trees in the foreground are blurred as the camera was tracking the sidereal motion of the stars. The ghastly, icky green color you see is Seattle light pollution reflected from high clouds. I sure wish our legislators would do something to curb the rapid advance of light pollution in our night skies - we live an hour from Seattle, out in the country, and can't photograph anything to the east unless the skies are perfectly clear and the humidity is zero. And we all know how often THAT happens here in the Pacific Northwest.

I wish something could be done about the light pollution! When we moved to where we are now about 17+ years ago we could go out at night and not see our hand in front of our face. Now we have all kinds of pollution coming from Seattle and Tacoma, we don't even need a flashlight anymore, it's sad.. I like your picture even though Jim, nice work..
