   I would like to expand a bit on your comments concerning
commonality of the ccd and film:

   Having a fair amount of experience in both fields, I feel
that there is a lot to be learned from attempting to emulate
film with ccds.  You are not going to get the critical feedback
from the SBIG group in this area.  I think most of us doing
either film or ccd work are trying to produce art.  Most of
the real artists are on APML.

   I initially bought the ccd to combine with film images.
Unfortunately my skies are just not dark enough for world
class film images.  With the film images that you and others
have there is a real opportunity to do some outstanding
combination imaging.  An example is using film to retain
the color in the brightest stars and ccd for the weaker
areas.  

   Filtering techniques are common to both ccd and film.
An example would be the new IDAS Nebula filter
that could provide some interesting enhancement when
used as a lum channel enhancer for RGB images.  How
about quad-color?  Chuck Vaughn's tri-color images
with his blue coverage into UV shows an artistic
capability that may be outside the reach of CCD.  IDAS
also a quad-color filter set that allows separation of
the near UV band so that violet could be introduced
as a new color in our imaging.

   I've rambled on too much.  But finally I would miss
the friends and the lively exchanges here on APML.  So
please excuse me if I post an occasional CCD image
on APML in the interest of exploring new techniques.
I still prefer to share the art with APML and I very
much enjoy the feedback.
