      Description

      Here is a chain of dark nebulae patches locate in the Constellation Cepheus, with the main one in the center of FoV being Barnard 169, Barnard 170 & 171 right below it, and Barnard 174 at the lower right corner of the image. They sit right next to the popular Elephant's Trunk Nebula, but often left out. It is quite a subtle job to extract contrasts of different levels of brightness from dark nebulae without overblown the background. There is a light layer of H-alpha signal in this area, but I just like the vivid color it brings in, hence admittedly slight overdone on H-alpha blending.
