Barnard 150 Seahorse Nebula

My latest astro project is Barnard 150. A dark nebula in the constellation of Cepheus. Also known as the Seahorse nebula.

A dark nebula (absorption nebula), is a dense interstellar cloud that obscures the light from objects behind it, such as background stars and emission or reflection nebulae. Interstellar dust grains located in the coldest, densest parts of larger molecular clouds cause light extinction.
