The Many Faced Swan

I finished gathering LRGB data for my Swan so I decided to process 3 more versions (in addition to the original NB SHO version) out of interest and to see which palette I preferred. All were processed as consistently as possible to see the relative effect of adding Ha and OIII to LRGB.

Unfortunately, I didn't catch a break with the seeing conditions with averages hovering between 2.7 and 3.6 arcsec/pix (before decon) for all filters ... pretty bad for an image scale of only 0.59 arcsec/pix!!

I think my favourites are the Hubble palette NB and the HaOIII enhanced RGB version.

Full res versions as usual:
Standard LRGB - the familiar "true colour" rendition:

LHaRGB - the Ha enhanced RGB rendition

LHaOIIIRGB - the Ha and OIII enhanced RGB version

SIIHaOIII (SHO palette) version (very slight reprocess from the original posting):
