The Pelican Nebula + Massimo Di Fusco + Optolong L-Ultimate


The weather is terrible this year, but I am not deterred by this and I try to take advantage of all the good glimpses. Thus, I managed to finish another subject in the Swan constellation, the Pelican Nebula.

The Pelican Nebula (also known as IC 5070 and IC 5067) is an HII region associated with the North American Nebula in the Swan constellation whose gaseous formations bear a vague resemblance to a pelican, from which it takes its name. The Pelican Nebula is located near the first-magnitude star Deneb, and is separated from its more prominent neighbour, the North American Nebula, by a foreground molecular cloud filled with dark dust. Both are part of the larger HII region of Westerhout 40.
The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from the young energetic stars is slowly turning the cold gas into hot gas and gradually advancing an ionisation front outwards. Particularly dense filaments of cold gas can still be seen, and among them are two jets emitted by Herbig-Haro object 555. In millions of years this nebula may no longer be known as the Pelican, as the balance and position of stars and gas will leave something that will look completely different.
