Pelican Nebula IC 5070

The Pelican Nebula (also known as IC 5070) is an H II region associated with the North America Nebula in the constellation Cygnus. 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 neighbor, 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.

Maxim DL 5.23, Photoshop CS6, CCDSharp

Notes:

This was my first image taken using the program AstroTortilla to plate solve and center the nebula before I began imaging.  The result was a dead center image over 3 nights of imaging.

Processing

  • Median combine in Maxim + Nonlinear stretch
  • 2 iteration deconvolution in CCDSharp
  • Levels and a small unsharp mask in PS6
