Image Information:  The Pelican Nebula (IC 5070) is part of a large star forming region with large dust clouds obscuring portions of bright ionized gas. The entire nebula is over 30 light years in size and about 2,000 light years away
Processing Comments:  This image was created by blending (Luminosity Mode in Photoshop CS/2) both the LRGB image (Red channel was a blend of red and H-alpha) with the Narrow Band image (SII, Ha, OIII using Hubble Palette).  Additional processing with curves, High Pass Filter and Kodac Gem.
