Excellent images! I think the new image is an improvement over the first (but as you say, subjective on my part as well). I think the added Ha data brings out more of the dark. Just looking at the images though, it looks like the processing might have been different - Ha may have been less stretched, or mapped at a lower factor, or some Ha was mapped into green? The blue (OIII) portions look a little richer too.

Hi Jim - Thanks. The processing was a little different because I just reprocessed the new data. The only intentional change was to stretch the O3 a bit more before combining the HOO so that made the Blue more prominent. I combined it straight HOO without adding any Ha into the G channel. I tried that but didn't like the colors.
I'm hoping to get some S2 data to try SHO processing for this target. We'll see if the weather cooperates!?
Nice to hear from you. Hope all is well.
Cheers - Steve
