Hi Rob, my understanding is that Halpha is deep red as in M42 or the red part of M20. Hbeta is the bluehish part of M20. In both shots we got on NGC2070 if I check my color balance I have all the RG&B histograms aligned and equivalent in width/size. I suspect that if you check yours they'll be the same. Having said that every single "original" shot I got of the Tarentula with the QHY8 has this green tint. Like yours.
I agree if you offset and stretch the red channel then you get what Doug ended up with. But is this the correct color? I mean if we applied the same stretching to our M42 shots we'd end up with a M42 that would be too red right?
