Faint Emission Lines and Temperature Fluctuations in M8
We present echelle spectroscopy in the 3500 to 10300AA range of the Hourglass Nebula which is embedded in the galactic HII region M8. The data were obtained using the 2.1 m telescope at Observatorio Astronomico Nacional in San Pedro Martir, Baja California. We have measured the intensities of 274 emission lines, in particular 88 permitted lines of
