Nice one Rick. I agree that RGB gives nicer colour than narrow band.

Barnard 343 is a much imaged dark nebula on western edge of LBN 223
which is part of the nebula complex 1.6 degrees west of Sadr. It is
almost always imaged in narrow band. I much prefer the colors from LRGB
imaging and the complex is certainly bright enough for this type of
imaging. I don't understand why it is so rarely done as the colors are
much stronger in LRGB than narrow band. Many posts of this object say
it is in the IC 1318 nebula around Sadr though I don't see that as
correct. Most sources make this nebula only about 50 minutes across.
It would have to be three times that size to reach to Barnard 343. Also
most images I found use high contrast that loses the detail inside the
nebula. It isn't totally dark as it has areas in which some stars and
nebula are seen through the cloud. Only part of it is so dense it
blocks everything behind it. Even then there seems a slight blue cast
across it due to something apparently closer to us than the obscuring
cloud or itself is scattering blue light to some extent while absorbing
everything else.
