van den Berg (vdB) 152 is a blue reflection nebula that glows at the bottom of a dark Bok globule called Barnard (B) 175.It is located 1.400 light-years away in the constellation Cepheus.
Near the edge of a large molecular cloud, interstellar dust in the region blocks most of the starlight behind it or scatter light from the embedded bright star giving parts of the nebula a characteristic blue color. Ultraviolet light from the star is also thought to cause a dim reddish luminescence in the nebular dust.

Embedded in the left side of the nebula is the Herbig Haro object HH 450, a jet emitted from a newly forming star. The thin, red filaments of a huge supernova remnant, SNR 110.3+11.3, in the left side of the image, appear to be approaching vdB 152 and may or may not collide with it in the future.

Dengel-Hartl (DeHt) 5 is a HII- and OIII-region, ionized by the white dwarf WD 2218+706 (the blue star in the center of the nebula). Beverly Lynds catalogued the brighter part as LBN 538.
