Rosette Nebula
The Rosette Nebula cluster lies 5,000 light-years from Earth and is roughly 130 light years in diameter. The radiation from the young stars in this nebula excites the atoms in the nebula causing them to emit radiation that produces the nebula we see today.
I decided to image the nebula in the palette of SHO (Sulphur II, Hydrogen Alpha and Oxygen II) to showcase the different emissions of this beautiful nebula. The channels SHO were assigned to RGB channels.
Recent surveys of the nebula have revealed the presence of numerous new-born stars inside the Rosette Nebula and its dense molecular cloud.
