M16, aka NGC 6611, aka
the Eagle Nebula, is in
Serpens, near the borders
between Serpens, Scutum,
and Sagittarius, and about
8000 lightyears distant. As
you gaze upon the Eagle,
you are witnessing the birth
of new suns -- their energy
causing the surrounding
gases to glow. Compare
with other stellar nurseries,
such as
M42 and M20.

Data acquired remotely at
CTIO in Chile.The master R,
G, B, OIII and Ha frames were
produced by
Jack Harvey
using CCDstack. I processed
these master frames into an
image, then layered the
central region with synthetic
luminance data from our
earlier version of M16. Jack
added additional refinements
to the image using
PixInsight.
