NGC 7000 "Cygnus Wall" and LDN 935 in Modified Hubble Palette, Ha, OIII, SII 8x15min each (1x1) , Imager Temp -10C, Cropped Slightly for Framing. What strikes me about this image is that the structure of NGC 7000 is almost unrecognizeable due to the color mapped nature of the data. Wavelengths were assigned in the traditional Hubble Pallette with Ha to green, OIII to blue, and SII to red. Then, because the Hubble Palette can be overly green, especially in Ha rich regions, the colors were adjusted to make the colorful and interesting format displayed here. Just as prominent in this image as emission nebula NGC 7000, perhaps even more so, is dark nebula LDN 935 (Lynd's Dark Nebula) - the dust that obscures the emission nebula to form the 'Gulf of Mexico' and dominates the entire right half of the image.
