In the Heart of the Rosette Nebula by Don Goldman

In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula.

The stars of NGC 2244 formed from the surrounding gas only a few million years ago.

The above image taken in January using multiple exposures and very specific colors of Sulfur (shaded red), Hydrogen (green), and Oxygen (blue), captures the central region in tremendous detail.
