I have found that luminance in HA, or a stacked combination of all my data (oiii, ha, sii) results in really really good clean final images with almost zero noise and great color.
One question I am finding myself asking is how much of a ratio should we be aiming for? Should we do 1:1 lum to color? (lum being ha or triad) or should we aim for 2:1 lum to color to get better, more crisp detail where the color is filled out after (x) hours sufficiently?
I just shot this pacman nebula and did roughly 11h in Ha, and 4h in Oiii. At this point to improve more, what would be the data to gather? I don't really plan on doing Sii as I like the color palette with this HOO rendition.
Should I be adding more Ha for Luminance or more Oiii?
What ratio in general should you aim for with Lum to Color data (oiii/sii)?
And finally has anyone used the TRIAD ultra for luminance channel? Do you find it better/worse/no different than a stack of all narrowband data?
