I put R and G where it seemed to ask for the files.
I'm not sure which file goes where....
Anyone got a good guide I can try?

Hi Glenn,
Am I reading this right that you discarded the blue channel after splitting them ? I’m not sure why you would do that ? O3 shows up in both green and blue channels but more towards the blue. Conversely light pollution tends to show more prominently in the green channel. I generally use a HOO composition for that reason if I’m using just Ha and O3 data. You can, as Martin suggested, go for an SHO with a synthetic S2. M20, as Martin said, is much better imaged in broadband as the blue is a reflection nebula. That’s the data side of things. As for processing in startools, I know nothing so this is where my help must stop
Cheers
