Scientific paper

In this work we present the results of mapping the planetary nebula NGC 6369 with long-slit spectroscopy. The observations were carried out with the CTIO 1.5 m telescope and Cassegrain spectrograph. Ten slit positions were observed across the nebula with a total exposure time of 11 hours. All positions were then combined to create ``images'' in emission lines like [O III] 5007, H alpha , [N II] 6584 and others. These images can then be used to study the classical diagnostic line ratios such as the [S II] doublet, which is a density indicator. The [S II] ratio maps, as well as the H alpha /H beta extinction maps for this object and total line fluxes for the most important lines are presented.
