This is NGC 6188, also known as the Great
Wall of Ara. It is an emission nebula and star forming region
about 4,000 light years away in the constellation Ara. Just
above the wall in the picture is the open cluster NGC 6193.
This cluster is an infant in Astronomical terms being a mere 1
-3 million years old. The stars in this cluster are largely
responsible for the emission nebula. The nebula spans about
600 light years.
Comments and suggestion appreciated.
