Interestingly, its spectrum appears to consist of only two wavelengths, a red one and a cyan one. The red one is H-alpha (656 nm). The cyan-colored one is O-III (501 nm). We don’t see a broad spectrum because the Ring Nebula, like most nebulae in the Milky Way galaxy, is an emission nebula. The picture is a stack of 60 one-minute unguided exposures.
