LBN 211 is an emission nebula in Cygnus, 5,500 light-years away
LBN 211 is an emission nebula in the constellation Cygnus , 5,500 light-years away. Lynds rated it brightness class 5 of 6, faint, and color class 3, reddish. It spans 4° × 1° of sky, about 384 light-years across. It is a faint target for long-exposure photography, and it is highest in the evening sky in September.
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.
