LBN 799 is an emission nebula in Taurus, 420 light-years away
LBN 799 is an emission nebula in the constellation Taurus , 420 light-years away. Lynds rated it brightness class 5 of 6, faint, and color class 3, reddish. It spans 2.3° × 10′ of sky, about 17.1 light-years across. It is a faint target for long-exposure photography, and it is highest in the evening sky in January.
Emission nebula: a cloud of gas, mostly hydrogen, made to glow by the ultraviolet light of hot young stars. It shines in the red light of hydrogen-alpha, and a nebula filter helps it stand out from the sky.
