If Andy Warhol were an Astronomer
A Warhol-esque treatment of the Trifid Nebula using the M20 HSOG one clicks from CHI-1. Right to Left, Top to Bottom they are...
- HSO
- HSO with Green mapped to Ha
- SHO with Green mapped to Sii
- HOS with SHO hue shift
- Green mono channel
- HSO with uncorrected stars
- HSO with Green luminance
- HOS
- SHO
It brings a whole new meaning to false colour - but a bit of fun too.
