LBN 591 is a bright nebula in Cassiopeia
LBN 591 (IC 10) is a bright nebula in the constellation Cassiopeia . Lynds rated it brightness class 3 of 6, moderately bright, and color class 3, reddish. It spans 6′ × 4′ 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.
