The Sadr region, IC 1318, is the busy neighborhood round the mag 2.2 star Sadr or gamma Cygni. It is a large expanse of nebulosity with dominant Ha emission nebulae and various dark nebulae.
We are looking deep into the Orion Arm of our Galaxy in this direction and the nebula is more than 3000 light years from us.
