When you look in the direction of Sagittarius, you are looking toward the center of our galaxy, the Milky Way. Sagittarius is rich in deep sky objects, and its star fields and brighter nebulae are spectacular. The constellation is a joy in any instrument, from one's unaided eye to the largest telescope.
