LBN 815 is an emission and reflection nebula in Taurus
LBN 815 (DG 40) is an emission and reflection nebula in the constellation Taurus . Lynds rated it brightness class 5 of 6, faint, and color class 3, reddish. It spans 1′ of sky. It is a faint target for long-exposure photography, and it is highest in the evening sky in January.
Emission and reflection nebula: a cloud where gas glows on its own, lit by the ultraviolet light of hot young stars, next to dust that scatters starlight. Photographs show red emission beside blue reflection.
