We have conducted a survey of 3.3 micron PAH emission in carbon stars, planetary nebulae, star forming regions and reflection nebulae using FLITECAM, a 1-5 micron camera and spectrometer developed for SOFIA. The survey sample was selected from ISO and IRAS target lists. All selected PNs have C/O ratios greater than 1. The initial survey was performed with FLITECAM on the Shane 3-meter telescope at Lick Observatory. FLITECAM's grism spectroscopy mode was used to obtain R 1700 spectra at both L and K band. In total, 41 objects were surveyed including 28 PNs, 6 carbon stars, 2 reflection nebula, 2 star forming regions and 3 galaxies, yielding 27 PAH detections. Using FLITECAM's wide field of view for imaging (almost 8' diameter), 3.3-micron PAH emission maps were made of NGC 7027, NGC 1333, the Orion Bar, the Trapezium and Sh 2-201 using a custom narrow band filter. These maps showed spatial displacement of PAH emission from Brackett-gamma emission. The maps were then used to place the most prominent PAH emission regions on the FLITECAM slit for follow-up spectroscopy. Additional follow-up was carried out using the NIRSPEC instrument on the Keck 2 telescope. For the more extended objects several slit positions were used to fully sample the PAH emission. The PAH emission feature exhibits changes in both central wavelength and overall shape depending on distance from the central UV source.
