ENHANCED IMAGES OF COMET SHOEMAKER - LEVY 9

1) Image #1 - top left
Original image taken from file  W930328.gif with following description :
This is an image obtained with the 2.3-meter telescope of the University
of Arizona  Observatories on Kitt Peak in Arizona  by Wieslaw Wisniewski
on 1993 March 28  at a mid-time  of  06:45:32 UT.  The total integration
time was 300 seconds.  North is to the right and East is at the top. The
field of  view is  1.3 arcminutes square.  This  is a  close-up  of  the
nuclear  train  showing  at least  12 individual nuclei embedded within.
Notice that the  southern boundary of the  nuclear  train is  very sharp
compared to the northern boundary.
 
2) Image #2 - bottom left
This image is a  linear combination of  four images obtained by using of
various  adaptive  filters on image #1.  The aim of image processing was
to enhance  the fine structures near comets nuclei.

3) Image #3 - right
Enlargement (nonlinear interpolation) of image #2 with increased
contrast.

Remark:
I am searching for more images like this in order to try adaptive filters
for structure enhancements. If somebody can help me or is interested
in cooperation with me, plese contact me.
