IC2177 - The Seagull Nebula in Monoceros
Copyright 2005 Hap Griffin
Also known as Gum1, IC2177 somewhat resembles the shape of a seagull, thus its more common name. Actually, the designation IC2177 only refers to the red emission nebula representing the seagull's "wings"...the brighter "head" nebula which also includes some blue reflection components is known separately as NGC 2327. A dark nebula protrudes into the nebula from the east.
This nebulosity complex lies at a distance of approximately 1,800 light years.
