Yeah... After looking at the past few shots from Vela, this is a bit
The pallet seems ok, However I don't know about using the SII as a L. It definitely highlights some interesting structure within the nebula...
M42 is one target that just never looks great in Narrowband... Anything that is prominently Ha generally looks pretty spiffy in NB, but as M42 is such a mix up of composite materials and gasses, it comes out looking like the aftermath of a nuclear explosion in NB...
Looking forward to some re-pros.. I know you can make something from the data..
PS - Express post me some clear skies!
