Although Aquarius is one of the oldest constellations known, it isn't terribly evident, with mainly fourth- and fifth-magnitude stars.
This late summer-early autumn constellation is just south of Pegasus and Pisces.
The most notable asterism is of the water jar itself, out of which The Water Carrier is pouring the water. This water jar is a Y-shape laying on its side, just to the east of alpha Aquarii.
Aquarius has the notable Helix Nebula as well as several pleasant binaries and an interesting variable.
