LBN 797 is an emission nebula in Auriga
LBN 797 is an emission nebula in the constellation Auriga . Lynds rated it brightness class 6 of 6, the faintest, and color class 4, the reddest, strongest on the red print. It spans 1° × 10′ of sky. It is a faint target for long-exposure photography, and it is highest in the evening sky in January.
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.
