IC 1340, otherwise known as The Bat Nebula and Caldwell 33, is a beautiful portion of the Cygnus loop supernova remnant that reveals delicate wisps and filaments of nebulosity. Sadly, it is often overlooked because of the notoriety of three other portions of the Cygnus loop, namely the Veil Nebula, The Witch's Broom Nebula, and Pickering's Triangle. IC 1340 is the continuation of the Veil Nebula. The nebula lies approximately 1,500 light-years from Earth.
