Hallingskies Posted July 21, 2021 Author Share Posted July 21, 2021 (edited) I use Astroart for prep and a very old version of Paint Shop Pro for pretty much everything else. I care not for the "Hubble Pallet", no science there, just personal preference. I use 100% Ha as red, and a blend of Ha and SII data for the green channel (I think I used 60/40 here) - this gives a nice yellow highlight to SII-rich areas without generating an overpowering green. I also blended a little SII into the OIII for blue (20/80) here. When I looked at the version I posted here, it was the oversaturated (wrong!) one: I usually crank up the saturation prior to adding a luminance overlay of Ha data, just to sharpen things up a bit. I added a 30% Ha lum layer for the version above. Edited July 21, 2021 by Hallingskies typo Quote Link to comment Share on other sites More sharing options...
