Description

IC 1318-Gamma Cygni Nebulosity (The Butterfly Nebula) (4 panel mosaic)

This image is a 4 panel mosaic, captured using a my 9.25 SCT. It is the most ambitious image I have attempted to date. I hope you enjoy. your comments and input are always welcome.

Distance: 5000 Light Years

IC 1318 is a giant HII region and one of the brightest among all the emission clouds in the Cygnus complex. The visible HII region spans over 100 light years. The bright star projected in the center of the nebulosity is a class F8 star known as Sadr or Gamma Cygni. Its true location is only 750 light years away and not related to the nebulosity which is much more distant at 5000 light years. There is considerable obscuration of the region due to intervening dust within the great rift of the Milky Way which attenuates the light of many of the bright stars spread through the region. The great rift represents a series of overlapping dark clouds that create a division in the Milky Way between the Cygnus and Sagittarius star clouds.
