LBN 581 is an emission nebula in Cepheus
LBN 581 (Ced 214) is an emission nebula in the constellation Cepheus . Lynds rated it brightness class 2 of 6, bright, and color class 3, reddish. It spans 20′ × 10′ of sky. It is a telescope object under a dark sky; a nebula filter helps, and it is highest in the evening sky in November.
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.
