First image is a 120 second exposure of comet Hale-Bopp. A 12 inch Maksutov telescope, working at a focal ratio of f5 was used with an SBIG ST8 CCD camera and a blue filter. The CCD was used in medium resolution mode, with 2 by 2 binning, giving a resultant pixel size of 18 microns. The field of view is 0.3 degrees (long axis) by 0.2 degrees (short axis). The image has been processed by subtracting a 20 by 20 median filtered masked version from the original to reveal structure in the coma.

Second image is the original unprocessed image. Third image is a false colour version of the original image.
