Description

This group of young stars is part of the immense nebular complex called the Heart Nebula (IC 1805). The image of Melotte 15 taken with my SO250/1400mm  telescope is 15 light-years across, while IC 1805 spans 300 light-years.The region surrounding Melotte 15 is a gigantic reservoir of hydrogen, which glows as a result of the intense ultraviolet radiation emanating from supermassive stars.
The IC1805 nebula, shaped of heart, I concentrated at the center of the heart, using OHS color combination.
