This complex
region is a trio of emission nebulas in front of a dark obscured
cloud in the Scorpius Milky Way. Centered in this field is NGC6357,
a mottled nebulosity surrounding the open cluster Pismis 24.
The entire group is about half a degree across with the cluster
glowing dimly at a magnitude of 9.4.
To the upper left
is an enigmatic more diffuse glow of LBN1117. Its huge at over
2 degrees in size and encloses such clusters as NGC6383, Cr337
and the beloved Antalova 2.
To the lower right
in our trio composition is the patchy RCW127, an infrared source
of great interest nearly a degree in size and surrounding the
open cluster VdB-Ha223, a five arc minute sparse glow with a
great many infrared stars hidden from view.
The rest of this
interesting field contains dark nebula, star clusters and a general
diffuse red glow from a background of hydrogen in this part of
the galaxy.
