Melotte 15 star cluster

Melotte 15
Image data acquired by Jim Misti

Here we have a brilliant star cluster (Melotte 15) superimposed on a nebula (IC 1805), which is the center portion of the Heart Nebula. The rich red color is due to hydrogen-alpha emission.

Processing details: The RGB image data combines green, and blue exposures with a combination of red and hydrogen-alpha (HaRGB).
