You know, Kurt, I probably stretched the Holmes' contrast in a bad way, because the comet is too small on the left side compared with your view and another I saw. Either that or my way of aligning with the stars somehow shortened the comet when it moved. I'm going to try and re-reprocess my original images. Thanks for your great info, Joe On Nov 18, 2007, at 12:22 PM, Kurt Fisher wrote:

Now try the Rotational Gradient tool -

or the Rank Filter (radius 7, width 0.5) to try and bring out some detail in the central condensation.
