Abstract

NGC 6369 is an elliptical planetary nebula with a filamentary halo and faint bipolar lobes. We present visual imaging and spectroscopy of the source taken with the Nordic Optical Telescope (NOT) and the Observatorio Astron\'omico Nacional at San Pedro M\'artir, Mexico (OAN-SPM). This is supplemented with imaging of the $\nu$ = (1$-$0)~S(1) $\lambda$2.121 $\mu$m transition of H$_2$ taken with the 4.2 m William Herschel Telescope (WHT), and mid-infrared imaging and spectroscopy acquired using the Infrared Space Observatory (\emph{ISO}) and Spitzer Space Telescope (\emph{Spitzer}). It is shown that there is evidence for H$_2$ emission in the near and mid-infrared, and that the $\nu$ = (1$-$0)~S(1) transition is weakly detected over an extended region. We also note that there is evidence for emission by polycyclic aromatic hydrocarbons (PAHs). Echelle spectroscopy confirms the presence of a bipolar outflow structure to the east and west of the central star.
