LBN 246 is an emission nebula in Cygnus
LBN 246 is an emission nebula in the constellation Cygnus . Lynds rated it brightness class 5 of 6, faint, and color class 3, reddish. It spans 45′ × 30′ of sky. 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.
