VdB 8 (also catalogued as Magakian 27 or LBN 643), is a small reflection nebula in the constellation Cassiopeia. Its most notable feature is its highly elongated, narrow shape. Situated between two dark (non catalogued) nebulae, VdB 8 almost overlays a distant galaxy visible in the same direction and cataloged as PGC 10828. The star lighting the nebula is the eighth magnitude HD 17443 - a blue-white main sequence star of spectral type B9, or A0. This star appears to be directly in connection with the nebula, being partially wrapped by it. A wider field, including VdB 7, VdB 9 and other objects can be seen below.
