Eagle Nebula – M16
The Eagle Nebula – M16
The Eagle nebula, the most icon nebula popularized by Hubble capturing it in 1995. I was able to capture this over 4 straight nights with good seeing but low southernly imaging. 302 images captured and stacked in 5 hours total imaging over 4 nights in Hydrogen Alpha, Sulfur, and Oxygen filters. Pretty happy with how this turned out and also processed it with stars removed to show the nebula contrasts.
