Van den Berg (vdB) 152 is a reflection nebula, 1,400 light years away in the constellation of Kepheus, which glows blue at the end of a dark dust blob called Barnard (B) 175.

Near the edge of a large molecular cloud, interstellar dust in the region blocks most of the starlight behind it or scatters the light of the embedded bright star, giving parts of the nebula a characteristic blue color. You can also see that the ultraviolet light of the star causes a faint reddish luminescence in the nebular dust.

100% detail:

Embedded in the left side of the nebula is the Herbig-Haro object HH 450, a beam ejected by a newly forming star. The thin red filaments of a giant supernova remnant, SNR 110.3+11.3, at the bottom right of the epsilon overview image seem 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.
