IC 1091 is a spiral galaxy in Libra
IC 1091 is a spiral galaxy in the constellation Libra . It shines at magnitude 14.0 and spans 1.1′ × 48″. 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.
