Description (wikipedia)The
Pelican Nebula (also known as
IC 5070 and IC 5067) is an
H II region associated with the
North America Nebula in the
constellationCygnus. The gaseous contortions of this
emission nebula bear a resemblance to a
pelican, giving rise to its name. The Pelican Nebula is located nearby first
magnitude star
Deneb, and is divided from its more prominent neighbour, the
North America Nebula, by a
molecular cloud filled with dark
dust.
The Pelican is much studied because it has a particularly active mix of
star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an
ionization front gradually to advance outward. Particularly dense filaments of cold gas are seen to still remain, and among these are found two jets emitted from the
Herbig–Haro object 555. Millions of years from now this nebula might no longer be known as the Pelican, as the balance and placement of stars and gas will leave something that appears completely different.
Personal noteI am happy with how the colors came out; not too flashy. I rotated the picture to make the nebula almost look like a mountain reaching into the blue sky. The main problem I had was the large haloes, especially in the O3 masters. I tried to remove them with the haloreduction script in PI, but that did not work. I probably need to upgrade my filters. The longer exposure times (600 sec) might have something to do with it as well.
