Van den Bergh 158 is the small blue reflection nebula at lower right around the 9.5 magnitude star HD 222142.

LBN 534 is the large area of nebulosity running diagonally in the frame in which VdB 158 is embedded.

This area is located in the constellation of Andromeda near the border with Cassiopeia.

The LBN 534 and VdB 158 area is sometimes called the Blue Flame.

The blue areas in the image are illuminated by starlight reflecting off tiny particles of dust. The very faint reddish-colored dust in the area is dust luminescing from the ultraviolet light from a nearby hot O or B type star.

North is to the top in the above image.
