NGC 2032 in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
There was almost no emission in S-II channel.
NGC 2032, the "Seagull Nebula" (Don't mix to the IC 2177 at Northern hemisphere, also called "Seagull Nebula") NGC 2032 locates in Large Magellanic cloud and it's in boundary to supershell LMC4. The gas is in various complex forms due the strong solar wind, radiation pressure, from massive stars in the nebula.
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.
