IC 4391 is an early spiral galaxy in Centaurus
IC 4391 (ESO 446-041) is an early spiral galaxy in the constellation Centaurus . It shines at magnitude 14.0 and spans 59″ × 42″. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in June.
Galaxy: a system of billions of stars, gas and dust held together by gravity, far outside the Milky Way. Spiral galaxies have a disk with arms; elliptical galaxies are smooth, round or oval swarms of older stars.
