Title: Spectrophotometric studies of gaseous nebulae. XXII. The irregular ring nebula NGC 6445

Abstract

The relatively high-excitation, low-surface brightness nebula NGC 6445 (8 + 3.1) deg shows a spectrum characterized by strong lines of He II lambda 4685, (Ne III! as well as STA0 II! lambda 3727, STAS II!, STAO I!, and probably STAN II!. The observational data strongly suggest an excess of helium. (auth)
