This is a two frame mosiac with the exposure times above for
each frame. The reddish nebulosity towards the top of the frame
is IC 4628. The bright concentrated cluster in the lower right is
NGC 6321. This entire region is north of Zeta Scorpii. By the unaided
eye, this part of the sky looks like a spray of stars coming from the
bend in the scorpion (beneath Antares). NGC 6231 is often referred to
as the "Northern Jewel Box."
