The Sadr Region (IC 1318) isn't actually one simple nebula. It is a large, complex emission-nebula region containing multiple bright and dark structures. The famous butterfly appearance comes from bright nebulosity separated by a prominent dark dust lane. There are also numerous additional dark nebulae throughout the field. IC 1318 is roughly 4,000 light-years away.
