We present the results of mapping the planetary nebula NGC 6369 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 H \alpha /H \beta 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 NGC 6369 .
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 NGC 6369 is matter bound , as about 70 % of the Lyman continuum flux escapes .
Using evolutionary tracks from ( ) we derive a central star mass of about 0.65 M _ { \odot } .
