TOA 130 with ASI 1600 and 3nm Astrodon NB filters
Ha: 124 300 sec
OIII: 43 300 sec
I started out wanting to mimic RGB using Ha and OIII--but somewhere along the line the Hubble Palette took over. I do have a red version of this image--but for some reason I am partial to the golden hues of the SHO palette--without the blue nhere, of course. Which is ironic, since OIII was used for both blue and green
