  We present the results of mapping the planetary nebula NGC6369 using multiple
long slit spectra taken with the CTIO 1.5m telescope. We create two dimensional
emission line images from our spectra, and use these to derive fluxes for 17
lines, the Halpha/Hbeta extinction map, the [SII] line ratio density map, and
the [NII] temperature map of the nebula. We use our photoionization code
constrained by these data to determine the distance, the ionizing star
characteristics, and show that a clumpy hour-glass shape is the most likely
three-dimensional structure for NGC6369. Note that our knowledge of the nebular
structure eliminates all uncertainties associated with classical distance
determinations, and our method can be applied to any spatially resolved
emission line nebula. We use the central star, nebular emission line, and
optical+IR luminosities to show that NGC6369 is matter bound, as about 70% of
the Lyman continuum flux escapes. Using evolutionary tracks from Bloecker(1995)
we derive a central star mass of about 0.65 Msolar.
