Re: [APML] Converting CCD Workflow to Film?

["Chris Cook" <ccook@cape.com>]

While the CCD images showing pin point stars are very nice, I still prefer
the trailed stars with the tracked comet.  It gives the viewer a sense of
motion.  Something which is normally lacking while imaging the heavens.  :-)
