As explained in Starstruck Tonight:
Continue eastward (from Scorpius) along the ecliptic to the next constellation, Sagittarius the Archer. Sagittarius was a Centaur, the wise Chiron, teacher of Hercules and brave in battle. If you cannot see a creature half-man and half-horse in these stars, then try looking for a teapot. Four stars make the pot... Two stars form a handle... One star is a lid... And the tip of the bowman's arrow makes a spout. If you look right where tea would pour out of the spout, you are looking toward the center of the Milky Way galaxy. The sky in this direction is filled with stars. Scan it with binoculars, and you will see cluster after cluster of stars, rising like little clouds of steam above the teapot.
