A pretty bright star-forming region in south-east Carina, part of RCW 57. We took this over the two nights immediately following full moon.
The left hand half of the image shows open cluster NGC 3603, presumably providing the UV illumination for the OIII-filled cave below it.
The right hand half provides a wealth of material for those who would see animal shapes. The NGC catalogues this region as including 3576, 79, 82, 84, and 86, but these don't seem to correspond to the zoo. Bottom right shows a totally convincing Hereford cow, celestial hoofer, dancing on back legs. Hereford because of the curly forehead. Notice the distended vein (dust lane) passing diagonally across the forehead, eye, and cheek. Middle right is elsewhere described as a "torchbearer", though Trish sees this region as Brunhilde at the opera, and it ain't over till she sings. On top of Brunhilde's head is a black leopard, howling. Arching magnificently over the entire top right is a plausible canopy for a covered wagon, skilfully constructed in 3D from interlacing shock fronts, strong in H-alpha (and SII if you expose long enough).
Green: H-alpha 3hrs; Blue: OIII 5hrs. Red: SII 4hrs, all 1hr subs. Aspen CG16M on 20" PlaneWave. Field 36'arc, North up. RA 11:28:50, Dec -62:45:30
