Seeing-limited 11.6-μm images of the central 1 parsec (~20 arcsec) of the Galactic Center have been obtained with a new 58 × 62 pixel Si:Ga array camera system. Previous array observations (Gezari et al. 1985) were used to derive the color temperature structure of the region. This higher spatial resolution work resolves new structure, showing a strong similarity (and notable discrepancies) between the 11.6-μm emission and the 6-cm continuum VLA maps (cf., Morris and Yusef-Zadeh 1986) and closely correlated Brackett a infrared array images (Forrest et al. 1986). Careful comparison of the dust and ionized gas emission distributions shows most of the compact 11.6-μm dust sources are displaced from the gas peaks.
