As with the Tarantula nebula I like the LRGB-image best.
The HαLRGB-version seems to me too much dominated by red. Here too the strong O3-signal, which is prominent visually, is missing. So I have to make O3 next time :-)

Nevertheless the HαLRGB-version is interesting, it gives the nebula a different character.
