Any tips in settings for either capturing or colour conversion would be greatly appreciated.
In what order were you doing your processing? Any darks/flats/bias frames must be done first, followed by debayer, before doing any stacking/rotation. Get this wrong and you'll never get the colour right.

Your colour cast is probably from light pollution, especially with yellow sodium vapour street lights.
