NGC 7000, The North American Nebula

Wikipedia entry.

Photographed at X-Bar Ranch, between Eldorado and Sonora, Texas.

First time I've dealt with a "meridian flip." With a German Equatorial Mount, when an object passes from the eastern sky to the western sky, you have to turn the mount so that the scope switches sides. Getting the camera realigned close to where it was was a bit tricky, but not terribly hard.
