Scutum
Scutum lies in a bright area of the Milky Way and is distinctive despite its small size. Its brightest stars are of only fourth magnitude, and none are named, but the constellation contains a celebrated cluster of stars popularly known as the Wild Duck cluster because its fan-shape resembles a flight of ducks.
Chinese associations
In the Chinese constellation system, five or six stars of northern Scutum, including Alpha, Beta and Eta Scuti, were grouped with others in Aquila to form a nine-star constellation called Tianbian. This represented a team of trade officials overseeing the organization and operation of markets. The area of sky to the west, incorporating much of Ophiuchus and Serpens plus southern Hercules, was visualized as a marketplace. Cite error: Closing </ref> missing for <ref> tag
