IC 1795 (also called the Fishhead Nebula) is a bright emission nebula, located about 6,000 light years away, in the direction of the constellation Cassiopeia and extending for 70 light-years in length.

IC 1795 is located at the top right of the Heart Nebula (IC 1805) and is a stellar maternity where new stars are often being formed.

In this colorful cosmic picture, obtained through narrow-band filters, where sulfur, hydrogen, and oxygen have been mapped to RGB, we can see incandescent gas clouds and dark concentrated dust fills.

The brightness of the nebula comes from young, warm stars inside it emitting UV radiation making the gas shine.
