Mitigating chromatic aberration

The Filter module's 'Fringe Killer' mode is an easy and very effective way to remove unsightly blue and purple halos caused by chromatic aberration.
Simply put the offending stars, including their halos in a mask (one can be automatically generated from within the Filter module, by clicking Mask, Auto, Stars or FatStars, Do, Keep). Next click a few times on different parts of the purple or blue halos and they will slowly disappear with each click.
