In the northeastern part of the constellation Cassiopeia, at a distance of 7 degrees northeast from ε Cas, you can find a small reflection nebula known as vdB 8. Its distinctive feature is its very elongated shape, stretching for about 3 arc minutes in NW-SE direction, while its width is less than 1 arc minute. This nebula reflects the light of an 8th magnitude B-type star (HD 17443) that is coincidentally positioned within it.
