I have been trying to image the Helix nebula and the Rosette Nebula over the past few nights. However, the Helix Nebula has eluded me due to my vantage point, it’s just below our tree line by the time it is dark enough and my attempts at the Rosette Nebula have been obscured by clouds. So last night I spent time on IC 5070 even though the moon has shown brightly, so this is IC 5070 through moon light.

IC 5070 and IC 5067
[1] (also known as the Pelican Nebula) 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.
[1]The Pelican Nebula is located nearby first
magnitude star
Deneb, and is divided from its more prominent neighbour, the
North America Nebula, by a foreground
molecular cloud filled with dark
dust.
[2] Both are part of the larger H II region of Westerhout 40.
[2]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.
[1] 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.
