A mosaic of IC 4628 and NGC 6231 - the SCO OB1 Star association

Description of object:

Our image shows a mosaic of the Scorpion OB1 stellar association between IC 4628 and the young open star cluster NGC 6231. This star cluster forms - with an apparent diameter of about 6 degrees - approximately the center of the SCO OB1 association.

The complete region is a large area of active star formation and the clusters in this image are all only a few million years old. 2 large dense dark clouds, Barnard 48 and Sandqvist 19 form an interesting contrast to the H-alpha region of IC 4628.
