About image
An image of the central part of the IC1805 Nebula in Cassiopeia, also called Heart Nebula due to its shape on large field images.
It is a wide HII region about 7500 light-years away: inside there are some small open clusters responsible for its ionization, among which the most significant is Melotte 15, composed of about fifty stars. This was my very first ccd image.
