Several series of ccd-images of the core region of comet Hale-Bopp were made at the prime focus of my Celestron C11. The one used, consists of 11 single exposures I took around 19:26 UT. Exp. time was one second. Both images shown, were median combined from single exposures where each was dark processed, flat fielded and registered. Some further processing brings out structure.
