The Horsehead Nebula SHO
B33 silhouetted against IC434 using an extended process that mapped SII, Ha, and OIII to colors that decently correspond to the visual colors of SII, HII, and OIII. In particular Halpha was mapped to the color of HII that I witnessed during the total eclipse of 2017 which included Hbeta producing a neon pink magenta.
