Veil Nebula Complex -> Ha added to Red,  OIII added to Blue.


The Veil Nebula Complex, a supernova remnant, formed from a supernova approximately 5,000 - 10,000 years ago.

In the upper left quadrant is the Estern Veil, NGC6992. Above right of center is Pickering's Triangular Wisp, NGC6979, and on the right with the bright star 52 Cygni, is the Western Veil, NGC6960. North is up.

Image was totally reprocessed (using LRGB data from the 21 Jun 2009 image) by incorporating Ha into the red channel, OIII into the blue channel; with 15% Ha also added to the blue. Ha and OIII were also added to the Luminance channel.
