LBN 845 is an emission and reflection nebula in Gemini
LBN 845 (DG 101) is an emission and reflection nebula in the constellation Gemini . Lynds rated it brightness class 4 of 6, moderately faint, and color class 3, reddish. It spans 40′ × 30′ of sky. It is a faint target for long-exposure photography, and it is highest in the evening sky in February.
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.
