IC 4670 is a planetary nebula in Sagittarius
IC 4670 (ESO 589-020) is a planetary nebula in the constellation Sagittarius . It shines at magnitude 13.2 and spans 5″. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in August.
Planetary nebula: a shell of gas thrown off by a dying Sun-like star and lit by the hot core left behind, which becomes a white dwarf. The name comes from their small, round, planet-like look in early telescopes.
