Excellent image John!  Nice work by Sean too.  Almost as good as CCD.......

A Happy New Year to all of you!

                      I finally got around to processing some shots of
NGC2392 taken back in
                      October, using Fuji Provia 100F +IUIC^_YQ_. f/11 on my
12"SCT. The best 3 of 5 images
                      were stacked in RegiStar, processed in Photoshop 6,
and touched up with
                      Bgsmooth.

                      The results were much better than my previous image of
this object from
                      early 2001, and a few days ago I showed the results to
my friend and fellow
                      APML'er Sean Walker. Since the noise level in the
image was reasonably low
                      (for film), he asked for the original RegiStar tiff
file so he could try his
                      hand at deconvoluting it with MaxIm DL. This helped
pull out even more
                      detail --- we have both tried our hand at film image
manipulation with MaxIm
                      DL in the past but this is a particularly interesting
result, I think. I did
                      feel the need however, to "soften" the result somewhat
by cloning in my
                      Photoshop version at about 20%.

                      And finally I put up a temporary page to show the
comparison of my original
                      result, and Sean's original deconvoluted version:

                      Comments of both flavors always welcome.
