Aquila and Scutum - the Eagle and Shield

Mythology - In many cultures this constellation foretold the coming of the summer monsoon season. In Greek mythology Aquila was the bird that brought rain and the keeper of Zeus' thunderbolts. It was also the eagle sent daily to tear out the liver of Prometheus as punishment for giving men the knowledge of fire. In one version of the story, Heracles kills this eagle with an arrow and rescues Prometheus.
Deepsky - The best open cluster is M11, the Wild Duck cluster in Scutum. It is a naked eye object, but looks superb through binoculars or a small telescope. It is fan shaped and contains over 300 stars.
Visibility - Aquila is best seen from August through September
