Aquila (The eagle)

Scutum, Aquila, CapricornusAquila is a  fairly easily recognized constellation of medium to bright stars that is one of the 48 constellations cataloged by 2nd century astronomer Ptolemy. It is a pretty constellation that easily evokes an image of a soaring eagle. Lying south of Cygnus, and flanked by Pegasus to the east and Ophiuchus to the west, Aquila reaches its highest nightfall ascension in September.

The most notable star in Aquila is Altair (Alpha Aquilae), its brightest star and a member of the Summer Triangle. Aquila lies in the same direction as the Milky Way, so several  gaseous nebula can be found in this constellation. The most famous of these are the Owl Nebula (NGC6781) and the Glowing Eye nebula (NGC6751),
