 Mythology of Aquarius

Aquarius is a well known constellation that represents a youth pouring water from a pitcher. The Water-pitcher is represented by a Y-shaped group of four stars, Gamma, Zeta, Eta and Pi Aquarii. The stream of water flows into the mouth of a large fish, represented by the constellation Piscis Austrinus to the south. Aquarius is a constellation of the Zodiac, the Sun passing through it from February 16th to March 11th.

 Best Viewed Objects/Stars

Zeta Aquarii

 A close binary, consisting of two white, 4th-magnitude stars that orbit each other every 490 years. Using high magnification, a telescope with an aperture of 3 in (75mm) or more should separate them.

(M2) NGC 7089 (Globular Cluster)

 A globular cluster, just too faint to be seen with the naked eye in all but the best conditions, but easy to see with binoculars or a small telescope. It resembles a fuzzy star.

NGC 7009 (The Saturn Nebula)

 A planetary nebula. When seen through a telescope with an aperture of 8 in (200mm) or more, it appears to have appendages that resemble the rings of Saturn, hence its popular name. A smaller telescope will show it is an 8th magnitude disk of apparent size to the globe of Saturn.

NGC 7293 (The Helix Nebula)

 Possibly the closest planetary nebula to Earth (only about 300 light-years away), and one of the largest in apparent size, at over a third of the diameter of the full Moon. Being so large, its light is spread over a wide area, making it difficult to spot. Under clear, dark skies, it can be seen through binoculars or a wide-field telescope as a pale gray patch.
