Gamma-Cygni-Nebula (IC1318) – also known as Sadr Region – is a diffuse emission nebula in constellation Cygnus. It is about 1500 ly away from earth. It was discovered 1893 by Edward Barnard (not to be confuse with Edward Bernays …), an astronomer from the US. He was one of the pioneers of astrophotography.

The Heart Nebula (IC1805) is about 7500 ly. away from our earth and located in constellation Cassiopeia. It was already discovered by William Herschel in 1787. With a bit of fantasy one can guess why the nebula was named Heart Nebula. The Heart Nebula is an emission nebula consisting of ionized hydrogen gas and dark dust lanes.
