This image shows you a vast H-alpha region just west of a major open cluster of M6 around the tail of Scorpion.
The nebula has a span of about 3 degrees but very indistinct, we cannot observe it with our naked eyes.
Long exposed photos can catch the nebula fairly easily with other nearby nebulae of NGC6357 and Cat's paw Nebula (NGC6334) and so on.
A central round nebulosity has a number of LBN1117 and a small one in northwest is Sh2-13.
