Tarantula nebula in AUS-2 wide field image. Processed from two One-Click Observations, one RGB and one HSO.
I processed this as a HaLRGB image where I created pseudo-luminance from RGB and then applied Ha to both L and R channels. I have to say that including the pseudo-luminance did not make any real difference. That sounds logical as there is no more real data available. I tried a few other mappings like RGB+HOO and RGB+HOS but liked this more than the others.
