IC 1795 Fish Head Nebula and IC 1805 The Heart Nebula
This nebula is located at around 7500 lights years from the Earth and extend over 165 lights years.
On the upper right part you can see the Fish Head Nebula (IC 1795).
On the left it is a part of the Heart Nebula (IC 1805) and you can see Melotte 15 in the middle of the Heart Nebula, a little star cluster with a lot of dust
