From the Wikipedia: "The Pelican Nebula is a large area of emission nebula in the constellation Cygnus (the Swan), close to Deneb, and divided from its brighter, larger neighbor, the North America Nebula, by a molecular cloud filled with dark dust.The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization front gradually to advance outward. Particularly dense filaments of cold gas are seen to still remain. Millions of years from now this nebula might no longer be known as the Pelican, as the balance and placement of stars and gas will leave something that appears completely different."
The most interesting feature in this region is the Herbig Haro object known as HH555, a bipolar jet emerging from the tip of an elephnat trunk with a C-shape and emitting in Ha and SII (see insert).
Data acquired for 4 nights (29 and 30 May 2009; 22 and 23 June 2009) at Muxagata, Portugal (MPC J15).
