Eagle Nebula – M16
The Eagle Nebula – M16
So after a night of experimenting, I was able to shoot the Eagle in Ha, Oiii, Sii. I ended up with only Ha and Oiii though as Sii failed to focus. I normally don’t process in HOO color palette, but this was still fun to get good clear signal on this target low in the sourthern sky. The Eagle was made famous with the pillars of creation in the middle of it when Hubble first released it’s images.
