This is a false-color composite of eighteen 2 s exposures of the inner 6 arcmin of the coma of Comet Hale-Bopp, taken in red light (Cousins R filter with polarizers) between 01:39 and 02:04 UT on March 29 with a Photometrics CCD camera (Thomson 512 chip) on the 0.4 m telescope at Limber Observatory.
The enlarged inset at upper right shows a spiral of material that looks to be coming from one end of the elongated nucelar condensation. However, the inset at lower right, which is a polarization image (brightness proportional to the degree of linear polarization derived from the same images with the right combination of orientations of the polarizers), shows a different spiral shape that seems to start from a strongly polarized (~15%) feature (dust jet?) at the opposite end of the nuclear region.

This image is the sum of 150 images taken with the 55 cm telescope. Each individual frame is a 4 second exposure with a R filter. The nucleus region is widely saturated, the goal of the observation is to show the large scale structure of the coma in connection with the small field but high resolution images of the 105 centimeter telescope. We can see a link between the dust shells of the internal coma and the "synchronic bands" in the dust tail. The image is enhanced with laplacian filter.
