RCW127

This is RCW127, the Cat's Paw nebula. This complex of HII regions contains one larger bubble (Gum 63) adjacent to three smaller bubbles (Gum 61, Gum 62 and Gum 64b) in addition to several other partially obscured nebulae and at least eleven major infrared sources that are probably mostly cooler B stars.

It lies at the same distance as NGC 6357, the War and Peace nebula, and is separated from it by a dark cloud. Both are near the Sco OB4 association in the Sagittarius arm.
