LBN 933 is an emission nebula in Orion, 1,300 light-years away
LBN 933 (DG 82) is an emission nebula in the constellation Orion , 1,300 light-years away. Lynds rated it brightness class 3 of 6, moderately bright, and color class 3, reddish. It spans 7° × 30′ of sky, about 159 light-years across. It is a telescope object under a dark sky; a nebula filter helps, and it is highest in the evening sky in February.
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.
