IC 1311 is an open cluster in Cygnus
IC 1311 (MWSC 3271) is an open cluster in the constellation Cygnus . It shines at magnitude 13.1 and spans 6.3′. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in September.
Open cluster: a loose group of a few dozen to a few thousand young stars born together from one cloud of gas. They drift apart over a few hundred million years and lie in the disk of the Milky Way.
