RCW85 Nebula - Emission nebula in the constellation of Centaurus. It is a H II region, mainly ionizated by two massive blue stars (one is HD 125 158 - left of the image). It has some star formation processes and the massive open cluster Loden 1256, which together with a dense dark globule form a single region..
