The return of the Milky Way Galactic Core means a return of some of night sky lovers’ favorite hydrogen and oxygen-rich emission regions. Our journey will take us through a few of them, with the hopes of capturing better details in the images I have captured before and new discoveries.
Soaring over what I consider to be the brightest region of the galactic core is the Eagle Nebula (M16). This cosmic raptor flies some 7,000 light years away from Earth in the constellation of Serpens. The nebula contains several active star-forming regions, including one of the famous areas referred to as the Pillars of Creation (zoomed below).

In processing this capture, I decided to experiment with a different color palette (referred to as HOO) to take advantage of the hydrogen and oxygen regions as captured with a 3nm dual narrowband filter. This palette creates sufficient contrast to allow the dark dust lanes to be accentuated throughout the rich hydrogen regions. This palette was made possible using Bill Blanshan narrowband normalization in PixInsight. It was definitely worth the experiment and I look forward to using this color palette more in my journey. Stay tuned, but in the meantime, remember to look up and experience an amazing Universe!
