NGC6231 and unknown nebulosity from Cambroon 2008-05-03

In all the excitement of another night at Cambroon I actually managed to get some imaging done (accompanied by much friendly heckling from my noisy dew collecting neighbours. Yes you know who you are. ).

Canon 20D/ED80/WO II FR. 7/5 min @ ISO800. Aligned and stacked in IP, post process in PS.

I found it a challenge getting this one colour balanced. I found I couldn't get the stars' colours to balance out. Then I checked the red channel and saw the extent of the gas cloud. I think I've taken it too far now and the background is too neutral. Yah live and learn.

The second shot is the red channel showing the extent of the cloud.

BTW does anyone know the designation of this nebulosity. I couldn't find it.
