Barnard 174 - Dark Nebula in Cepheus
This is dark nebula Barnard 174 in the constellation Cepheus. 1.5 hours just starts to bring out some edge details, so I'll call this a work in progress for now.
E.E. Barnard published a list of dark nebulae in 1919, known as Barnard objects, they number from Barnard 1 to Barnard 370.
