LBN 749 is an emission and reflection nebula in Perseus, 1,020 light-years away
LBN 749 (Ced 18a) is an emission and reflection nebula in the constellation Perseus , 1,020 light-years away. Lynds rated it brightness class 6 of 6, the faintest, and color class 2, bluish. It spans 2.5° × 1° of sky, about 44.5 light-years across. 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.
