The North American Nebula and Pelican Nebula (click on)



November 19. 2005

The Pelican Nebula (can you see it?) is the celestial next door neighbor to the North American Nebula. Together, they make up a 6 trillion mile expanse of Hydrogen-alpha star forming nebula in our own Milky Way Galaxy. This area of the sky is faintly visible under very dark skies in the constellation cygnus, next to the very bright summer star Deneb. This photo is a composite of 9 15 minute exposures through a lumicon hydrogen alpha filter. Using the red channel exclusively and then converted to greyscale. Canon 20d with internal noise reduction on, ISO 800.
