In the centre of the image is a ring nebula around the Wolf-Rayet star WR 75. Wolf-Rayet stars represent a phase in the evolution of very massive stars which produce powerful stellar winds. Most of them are believed to become in the future a Type 1b or 1c superova. At the bottom (about 5 o clock from the nebula) is seen the open cluster NGC 6115. It is situated at 3175 light-years from Earth and thought to be around 870 million years old.
