Image of nuclei of Hale-Bopp comet taken with a Meade SCT 10" F5 (FL:1275mm). I use a CCD camera SBIG ST6 and a number of 10 images exposed 1 sec were taken. All the 10 images were added and processed by unsharp masking. The blue color of the comet were added to increase the look and are not the real color of Hale-Bopp. The image is very similar as we can see now when you observe Hale-Bopp with a telescope.
