We present the preliminary results from a NASA/JHU sounding rocket mission (36.136 UG), launched on 14 June 1999 at 01:40 MST, to obtain a long slit (200\arcsec x 12\arcsec) spectrum of the Dumbbell Nebula (M27, NGC6853) in the 900 -- 1400 Angstroms wavelength region. Emission lines of C 2, N 3, He 2, and H 1 were recorded along with the continuum spectrum of the central star. We also tentatively identify a continuous emission longward of Lyman α as resulting from H 1 two-photon emission. Nearly concurrent long-slit spectroscopy was obtained from the Apache Point Observatory using the Dual Imaging Spectrograph in the low resolution mode covering the 3800 -- 9800 Angstroms wavelength regime. In future work we intend to constrain the density and temperature of the excited gas by comparing our far-UV and optical spectra to photoionization models of the nebular emission. The far-UV observations were supported by NASA grant NAG5-5122 to the Johns Hopkins University. The optical observations were obtained with the Apache Point Observatory 3.5-meter telescope, which is owned and operated by the Astrophysical Research Consortium.
