We report postperihelion imaging of the dynamically new Comet Austin ((1989 \mathrm{c} 1=1990 \mathrm{~V})) obtained with the UCSD mid-infrared astronomical camera (the "Golden Gopher") during five nights in May 1990 . The (64 \times 16) array format of the camera covered 53 (\times 13) arcsec of the sky. The images were taken through a wide 9- to (12-\mu \mathrm{m}) filter and a narrower 8- to (9-\mu \mathrm{m}) filter. During the observing run, the heliocentric distances ranged from 0.8 to 0.9 (\mathrm{AU}) and the geocentric distance ranged from 0.5 to (0.4 \mathrm{AU}). The inner ((16 \times 4) \times 10^{3} \mathrm{~km}) of the coma was sampled with a linear resolution of (290-220 \mathrm{~km}) per pixel. The images obtained on the same night looked similar and were combined together to enhance the signal-to-noise ratio in the coadded images. No jet- or shelllike structures are observed. The coma is slightly elongated along the projected Sun-Comet direction, but there is no systematically higher intensity sunward over anti-sunward. Radial brightness profiles correspond to the steady-state model approximation of (r^{-1}) up to an angular distance of 4-5 (\operatorname{arcsec}\left(1-1.5 \times 10^{3} \mathrm{~km}\right)) from the nucleus but steepen to (r^{-1.25}) at larger distances. This is consistent with the presence of fading grains in the close vicinity of the cometary nucleus. The thermal infrared flux measured in the images decreases as (R^{-5.5}) with the heliocentric distance, suggesting a (R^{-3}) dependence of the dust production rate. The estimated mass loss rate was (1 \times 10^{6} \mathrm{~g} / \mathrm{sec}) on May 6 and (5.7 \times 10^{5} \mathrm{~g} / \mathrm{sec}) on May 12 , giving a dust-to-gas ratio of 0.25 . A map of the spatial behavior of the silicate emission in the coma was generated by comparison of the images obtained on May 12 through the two different filters. This shows a peak in the sunward direction at a distance of (1.5-2 \times 10^{3} \mathrm{~km}) from the nucleus. The results presented here are the first application of the Golden Gopher camera in cometary research and they demonstrate the potential of mid-infrared array
