vdB 152 is comprised of two objects. One is Barnard 175, a dense pillar of cosmic dust known as a dark nebula. To the right of the dark nebula is blue reflection nebula Cederblad 201. Inside this reflection nebula is a blue-white main sequence star, BD + 69 1231. The star is magnitude 9.29 and its radiation gives the surrounding gases a bluish color. Also seen in the background are faint traces of hydrogen filaments from SNR 110.3+11.3 supernova remnant.
Together, they are known as Van den Bergh 152 and is located in the constellation Cepheus
