OBJECT DESCRIPTION AND IMAGE SESSION

Also known as LDN 1771 or the Parrot's Head Nebula is located 3 degrees north from Messier 7. It has a rich star field background which brings contrast to the dark area.

Edward Emerson Barnard was an American Astronomer born in 1857. Being an pioneer astrophotographer he complied a list of Dark Nebulae known as the Barnard Catalogue with 370 objects. The list was published in 1919. Most of his work was done by taking photographs of the Milky Way. His best known discovery was the Barnard Star in 1916.
