The advent of submillimeter wavelength array cameras operating on large
ground-based telescopes is revolutionizing imaging at these wavelengths,
enabling high-resolution submillimeter surveys of dust emission in star-forming
regions and galaxies. Here we present a recent 350 micron image of the edge-on
galaxy NGC 891, which was obtained with the Submillimeter High Angular
Resolution Camera (SHARC) at the Caltech Submillimeter Observatory (CSO). We
find that high resolution submillimeter data is a vital complement to shorter
wavelength satellite data, which enables a reliable separation of the cold dust
component seen at millimeter wavelengths from the warmer component which
dominates the far-infrared (FIR) luminosity.Comment: 4 pages LaTeX, 2 EPS figures, with PASPconf.sty; to appear in
