Notes

The North American Nebula (left) and Pelican Nebula (upper right) shown here are separated by an intervening dark absorption cloud known as LDN 935. The Gulf of Mexico portion of the North American Nebula is an intricate mix of gas and dust that draw the attention of the viewer to this area. Given extremely dark skies with high transparency, the North American Nebula can actually be detected with the naked eye. The neighboring Pelican Nebula has a much lower surface brightness, making it strictly a telescopic object. Finely defined streamers of dense, colder gas along the ionization front of the Pelican Nebula (upper right corner) serve to etch out the familiar pelican's beak, giving rise to the name of this object.

Also shown in this wide field image (right center and bottom) is the emission nebula IC 5068, beautifully streaked with dark clouds of thin dust across its surface.
