Van den Bergh 152, also known as Cederblad 201, is a blue reflection nebula at top left in the image. The large dark nebula stretching through the frame is Barnard 175, a Bok Globule. This complex, also called Wolf's Cave, is located about 1,400 light years away in the direction of the constellation of Cepheus.

Full of very faint dust, this area is part of a large molecular cloud named the Cepheus Flare by Edwin Hubble. The opaque dust blocks most of the starlight behind it, but blue light from a young star is scattered and reflected off some of the particles to illuminate the reflection part of the nebula. Some of the faint dust may be glowing in a dim red color from luminescence, forming an Extended Red Emission nebula (ERE).
