Scientific paper

Observations of the Crab Nebula using a new CCD imaging/spectropolarimeter are described. Two large regions each 150 arcsec across were observed with a seeing-limited spatial resolution of 1.5 arcsec. The pulsar was included in both fields. In general, no evidence is found for substantial small-scale structure in the projected magnetic field, but there are changes on the order of 5 arcsec which would be barely discernible by photographic methods. There is remarkable organization of the field over domains ranging in size from 10 to 30 arcsec. The polarization maps are consistent with the idea that power from the pulsar emerges partly as a 30 Hz wave and partly as a relativistic wind containing a toroidal field. Away from filamentary structure the magnetic field could be expected to be fairly well ordered, as is observed. The nebular polarization is quite uniform close to the pulsar but the position angle changes steadily with radial distance.
