IC 1805 is known as the Heart Nebula, for obvious reasons. It is a large emission nebula that spans almost 2 degrees in the sky. The brighter central region and its surrounding cluster is cataloged as Melotte 15. The bright nebula at the tip of the heart is also cataloged as NGC 896 or IC 1795, and is known as the Fish Head nebula; it was the first part of the nebula discovered vt William Herschel in 1787. The Heart Nebula is located about 2300 light years away in Cassiopeia.
