NGC 6369
My take on this beauty. This one was very interesting to process because there were 6 different filters, 3 of which were narrow band. Roughly equivalent colors as follows:
Red: IR+NII
Green: 555w+Ha
Blue: 439w+OIII
A little background: Again, I used the usual NASA/Hubble Heritage/STScI image to give me ideas on how to execute my version. While theirs did a very good job of showing all the complex structures of the NII regions, it didn’t show the fainter areas of H-a
much at all. It also had a strange but interestingly nacreous color scheme and I’m not entirely sure how it arrived at that. I was very tempted to make the NII regions a more aesthetically pleasing blue or red color instead of the green but then it would be very difficult to tell it from the other narrow band spectra.
