Hi Stephen -

I never made a transition. Before about 18 months ago I never did any
astrophotography at all. Frankly, the idea of getting images right away from
a CCD camera and my existing degree of comfort manipulating images in
Photoshop is what attracted me. Ironically, I am now starting to do some
film work for those cases that work better on film, so my transition is
actually the *other* way!

An example of why I am using film on some objects is the Pleiades. On CCD,
by the time you get the reflection nebula to show up the stars are
hopelessly overexposed. Even if you chop up the exposures into little short
ones to avoid blooming it seems like halation is worse on a CCD chip than on
film thus bloating the stars. Film has an anti-halation layer and of course
does not bloom.

Eeek! I said CCD. I'll duck now.
