LBN 245 is an emission nebula in Cygnus
LBN 245 (IC 1318B) is an emission nebula in the constellation Cygnus . Lynds rated it brightness class 1 of 6, the brightest, and color class 3, reddish. It spans 45′ × 20′ of sky. It is among the brightest nebulae in the catalog, visible in a small telescope; a nebula filter helps, 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.
