Thanks James, this was shot with a cheap Canon 50mm f1.8 lens so at full aperture it suffers from aberrations such as coma and CA at the edges. I know from past experience that stopping down beyond f5.6 almost eliminates this.
I shot the UVIR subs at 90 secs, f 8 800 iso, due to the filter's high transparency and 120 secs, f 5.6 1600 iso, to compensate for the low transmission properties of the CLS CCD filter.
