Description

People have likely looked up at the sky and seen shapes in the clouds for thousands of years. Even more interesting, however, is when those shapes are also visible in the celestial clouds - large pockets of gas in space, energized by the radiation of nearby stars.

This wide field image shows two such clouds - nebulae - in the constellation of Cygnus the Swan. On the left is NGC 7000, known as the North America Nebula. The outline of the entirety of North America, from Canada down into Mexico, is clearly visible. On the right is IC 5070, called the Pelican Nebula due to its distinctive shape.

RGB data for this image was captured from Courtright Reservoir and the H-Alpha data was captured from my backyard in Clovis, California.
