Scientific paper

We report the imaging of two planetary nebulae (NGC 7027 and BD+30o3639) with the OSCIR instrument of Gemini North Telescope. Observations were taken at 5 filters (10.3, 11.7, 12.5, N and 20.8 microns) and mosaic images were constructed from 5-point maps. The dust shell in these two objects are clearly resolved with 0.4 arc sec resolution (at N). Comparison of the images at 11.7 microns with the images taken at adjacent 10.3 and 12.5 microns continuum filters suggests that the emitting region of the 11.3 micron aromatic feature arises from outside of the ionized region of the nebulae.
