This picture was taken at 1:00 AM. It is looking east from my backyard observing site. The only illumination is the light pollution present at my suburban location. It was taken with a hand held digital camera and is not a time exposure. The pollution consists primarily of low pressure sodium illumination but there is a componant of mercury vapor illumination as well. This can be seen on the right portion of the image above. That glow is coming from a parking lot. In spite of the very bad light pollution, I am able to perform usable telescopic observations and imaging.
