Observations of the Crab Nebula at 850 micron made with the "Submillimetre Common-User Bolometer Array" (SCUBA) on the James Clerk Maxwell Telescope are presented. A variety of chop-throws and scanning directions was used in these observations, to well sample structure over a range of scales and directions. The resulting image, which was restored using a MEM algorithm, has a resolution of 17 arcsec, and has been compared with a 20-cm VLA image of the Crab Nebula to study spectral index variations. The 850-micron and 20-cm images are very similar, implying that there is little variation in spectral index across the face of the remnant between these wavelengths.
