This is an RGB + SHO image of the "Great Wall" in Cygnus ... it is a part of the North American Nebula. Taken with a Stellarvue 180mm f/7 APO refractor and a ZWO 6200 full frame mono camera with Chroma filters. Reduction done in CCDStack, all processing done in PS CC. We used channel swapping to make the image. Be sure to zoom in ... lots of fascinating detail.
