This image of the nucleus of comet Hape-Bopp was made under worst conditions. The comet appeared next to a street light, and the whole location was blanketed by fog. It was impossible to see anything of the nucleus even with the help of a pair of 7x50 glases. But the long exposure time of 8 seconds (to be compared with a quite similar image I took 3 days before with 0.3 sec exp. time ) gave an impression of the nuclear region as it appears, when viewing the comet through the telescope under better conditions.
