Wolf's Cave Nebula

The image shows a blue reflection nebula, catalogued as VdB 152 or Ced 20, which is radiated by a white-blue star. It lies at the tip of the long dark nebula, Barnard 175, which itself forms part of a dusty complex been called Wolf's Cave (LBN 528). Towards the upper right lies the planetary nebula PK111+11.1; and filamentous Ha nebulosity belonging to a super-nova remnant flows across the image.
