Yeah, I know Geoff, hard to define huh..? I guess what I mean is and at least to my eye, some areas just don't look as good in narrow-band (ie without
any RGB) as they do in LRGB or even LHaRGB even if you have chanel mixed to approximate an RGB mix
Some areas look better in Narrowband than they do in LRGB too, a good example is the fighting dragons and Running chicken areas, both look a little flacid in LRGB compared to SIIHaOIII. The Trifid region is another good example, decidedly drab, even kinda dirty
in narrowband or any mix close to that, looks
much better
in LRGB.
There are many good examples of what I mean with the NGC 6559 region but just recently Steve Mohr posted an
LRGB shot of the same field taken with the same scope and image scale as yours, so you can compare easily.
Hope that made sense
