Unusually, nitrogen stronger than hydrogen and oxygen, some sulphur DSS2 image, 10 arcmin square

Of all the spectra of planetary nebulae I have now obtained so far this is the only one with both nitrogen lines giving the strongest signals. All others have either hydrogen or oxygen as the strongest lines. The intense nitrogen emission is responsible for the red colour of the nebula.
