The only light pollution is the low dome on the horizon. This location seems to always have orange horizons, I put it down to being the dusty wheatbelt
There is some green airglow which varies the orange.

No selective saturation done, in fact the entire set of changes to the raw image were:
- a single levels layer (no mask)
- a single saturation layer of 10%+ on the master channel (no mask)
I haven't quite worked out the halos ... don't always get them with this lens but have in some shots. Only on the 6D not on the 7D so far. I am wondering if it is as much blooming combined with white balance as it is CA.
