Observer: Alain Klotz
Location: Pic du Midi Observatory, France
Date: March 4-5, 1997

This image is the result of the substraction between one image taken on March 5.24 and one other taken on March 4.25. Bright areas are seen at the outer edges of the Z features. It is the demonstration that the dust flow expands from the nucleus. The nucleus can be seen by the two perpendicular small bars. The scale of 1 arc min is the vertical bar on the left. North is down. Image taken with the infrared camera (MOICAM) on the Telescope Bernard Lyot.

irst image is a mosaic of seven original images, 11 seconds each with 150mm (6") Maksutov - Cassegrain f/15 + Barlow lens 1.3x and Cookbook 245 CCD camera. Second image is a result of processing of the same images and reveals inner coma structures - envelopes present there (they are not an artefact of image processing), caused probably by rotating jets.

Date: March 5, 1997 10:17-10:41 UT

First image is a five minute (300 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 Lumicon Swann Band 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 using Mira. A 45 by 45 median filtered masked image was subtracted from 105% of the original. A false colour pallate was then added. The second image is the original 300 second exposure used to make the top image on this page. It has been flat fielded and dark subtracted. Third image is a false colour version of the 2nd image. The fourth image is 30 second exposure and was taken through a 12 inch Maksutov telescope, working at f5. A lumicon Swann Band filter was also in the optical train. The image has been processed by subtracting a 10 by 10 pixel blurred median filtered image from the original.
