Description

I'm still playing with narrowband mixes. I started with a SII enhanced bi-color using SII/Ha for Red and OIII Ha for green. Then I tried a straight SHO mix. Couldn't decide which one so I averaged the two. That should mean:

Red = 75% SII, 25% Ha
Green = 75% Green, 25% OIII
Blue = 100% OIII

Ha 14, OIII 20, SII 21 all 1200 seconds for a total of 18.333 hours.
