IC-5070 - The Pelican Nebula
Copyright 2009 Hap Griffin
called the "Pelican Nebula" lies 2000 light years away in the
constellation of Cygnus. Dark dust clouds in the nebula define the
Pelican's eyes and long bill, while a bright region of glowing hydrogen gas
outline the back of his neck. As this region of active star formation
evolves over time, a few million years from now it will no doubt no longer
resemble its namesake.
This image was captured through a narrowband filter admitting only a narrow slice of spectrum around the wavelength of glowing hydrogen. Thus it is a monochrome (single color) image displayed as shades of grey. Considering the thickness of the haze and the passing clouds, it is amazing that the hydrogen-alpha filter pulled out as much detail as it did.
