The Veil Nebula

About this image:

(Text Credit Wikipedia) The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop (radio source W78, or Sharpless 103), a large but relatively faint supernova remnant. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light-years.[2]

This image is a mosaic of 4 panels in LRGB taken with a SBIG STL full frame camera and 6 panels of 3nm Narrow Band images taken with a QSI 583 camera on a Stellarvue SVS130 f5 refractor.
The narrow band data was merged with the LRGB data in PS CC using spectral mapping.
