Nice picture, but did you use filters ?
This object is not too far north (decl -32) to see in AU even as far south as VIC it rises enough above the horizon.
Of course here in NL it rises higher but the sky is more light polluted ...
Visually I could see it easily with an 80mm (x500mm) short achromat with a UHC last night.
It looks like a bit like false color.
Last night I took the whole area with a Canon 85mm f/1.8 squeezed to f/.5 a single frame 4 minutes @ 1600 with Astronomik CLS:

I took the 6992 the night before without filters with the EF 300 f/4-5.6L full aperture 2 minute frames stacked, see here the results:

Last night I took also 2 minute frames with filter but I could not get the colors right. Those ugly magenta stars ...
