This elongated dark nebula is called Barnard 150. It's sometimes referred as the Seahorse nebula for obvious reasons. An American astronomer Edward E. Barnard (1857 - 1923) is well known for studying these dark nebulosities, this nebula was the 150th object in his catalogue of dark objects.
The nebula lies at a distance of 1200 light-years from Earth in the Constellation of Cepheus. Because the nebula is in the Milky Way's plane it stand outs from the background filled with colourful stars of our galaxy, a keen eye can also distinguish three separate dense dust cores that actually are star formation regions.
