The Submillimeter High Angular Resolution Camera (SHARC-II) is a facility instrument for far-infrared (350μm) imaging at the Caltech Submillimeter Observatory (CSO). With 384 pixels, SHARC-II uses the world's largest bolometer array for astronomical observations. SHARC-II is most efficiently utilized for observations of extended sources and for deep sky surveys. The low 1/f detector noise allows total power measurements without the need to observe an emission free ``off position''. This is possible because the sky emission can be distinguished from the celestial emission when the array scans over the sky at sufficient speed. Here we present a representative set of SHARC-II observations, which highlight the capabilities of the instrument. The observations show the submillimeter continuum emission from our own Galactic center, the nearby galaxy M51, and the gravitationally lensed high-z Cloverleaf galaxy H1413+1143.
