This is another further wider frame of the area taken with dual narrowband filter. Thanks to the filter, the omega-shaped faint object RCW 59 presented with nice clarity.

RCW62 60 minutes of integration in SHO with Takahashi FSQ-106ED 106/382 f 3/6 telescope, QHY 600M Pro camera, are 12 shots of which in Ha 4x300s, in OIII 4x300s and in SII 4x300s, processing with Pixinsight and Photoshop. All data and shots were captured with Telescope Live. The large bright nebula IC 2944 (RCW 62/Gum 42) corresponds to the "body" of the Running Chicken nebula complex, which is ionized by the Cru OB1 association.

According to Avedisova, the nebula is ionized by the giant O6 III HD 101190, the star O6 V HD 101436 and the subgiant O9 IV HD 101223 as well as the supergiant B0.5 Iab HD 101545. (SIMBAD provides a much more interesting B6Ib/II class for HD 101436.)

A 2013 study notes that X-ray sources in this direction are concentrated around the star O8 V HD 101205 suggesting that this star could also be associated with the nebula.

Avedisova places RCW 60, RCW 61, RCW 62, Gum 39, Gum 40, Gum 41, Gum 42 and IC 2944 in the star formation region SFR 293.64-1.41 with 51 components, including 7 masers and 18 infrared sources. Humphreys says that hot stars in this direction form the Cru OB1 association at an average distance of 2510 parsecs.

Dutra and colleagues state that RCW 62 contains the infrared group [DBS2003] 69, although curiously they provide a distance of only 1700 parsecs.
