The Sagittarius ("Sagitta" is Latin for "arrow") is a member of zodiac just west of Scorpius, bathed in the summer's Milky Way, so includes plenty of attractive nebulae and star clusters. The constellation also includes the center point of our Galaxy.
Sagittarius represents Cheiron who has a body of half-man and half-beast, taking a stance to shot an arrow at the scorpion. The asterism of that is well known as "the teapot" in the west, and ancient Chinese had regarded that as another dipper (of course for the Big Dipper in Ursa Major).
