Ken Wallker took this amazing shot of Lynds's Dark Nebula.

He wrote: "The dark nebula is scattered throughout the image in this HII region. The data was acquired over 5 nights with the narrow band being the main focus. RGB data was mainly for the stars and reflection nebula which was missing in the Ha and SII wavelengths

A dark nebula or absorption nebula is a type of interstellar cloud, particularly molecular clouds, that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae. The extinction of the light is caused by interstellar dust grains located in the coldest, densest parts of molecular clouds.(wiki)
