RCW61
RCW 61 forms the feet of the Running Chicken nebula complex.
According to Avedisova, RCW 61 is ionised by three O9 giant stars: HD 100099 (O9 III), CD -62 535 (O9 II) and HD 100444 (O9 II), as well as three B-class stars. (SIMBAD reports that CD -62 535 and HD 100444 are the same star.)
She places RCW 60, RCW 61, RCW 62, Gum 39, Gum 40, Gum 41, Gum 42, and IC 2944 in star formation region SFR 293.64-1.41 with 51 components, including 7 masers and 18 infrared sources. Humphreys says that the hot stars in this direction form the Cru OB1 association at an average distance of 2510 parsecs.
