Orion Nebula NB/HDR, with all kinds of technologies in there, but didn't seem to achieve what was expected. It looks that the 60s under an F/7 scope is too much longer than enough to over-saturation, though the exposure lever is at about 0.2 at the central part. HOS was chosen as the final color composition, because it looks more natural than other combinations (yes, I tried all combinations).
