This image shows an area of the constellation Cassiopeia near the border with Cepheus, about 1.5 degrees southeast of the nebulous complex NGC 7822 (or Sh2 - 171), which northern part is visible in the lower right corner. In the lower left makes its appearance another Sharpless object: Sh2 - 170 (or LBN 577). VdB 2 (also known as Ced 1) is a small reflection nebula, which is illuminated by the 10 mag. blue-white main sequence star HIP 1077. The nebula reflects the blue light of the star, taking itself a bluish color; the surrounding regions show signs of darkening by non-illuminated dust. The distance to VdB 2 is estimated to be 1100 parsecs (about 3590 light years). At the left from the center (please see an annotated mousover) is located the small planetary nebula catalogued as PLN 118 + 2.1. A highly magnified crop of this nebula can be seen below:
