IC 1805 - NGC 896 (IC 1795) - The Heart and The Fish Head Nebulae

IC 1805 (also known as the Heart Nebula) is a diffuse nebula in association with an open cluster , visible in the constellation of Cassiopeia.

It is a very large HII region , whose distance is estimated to be around 7500 light years from us; its main feature is the presence of two large apparently empty areas, of different sizes, which make the nebula similar to a "heart". Inside there is a system of small open clusters not very concentrated, responsible for the ionization of the nebula. The most notable of these is Melotte 15, which contains some stars about 50 times more massive than the Sun.
