The inspiration for this "idea" is from Robert
Reeves most excellent book
WIde Field Astrophotography as well as some of the
H-Alpha pictures
the CCDers are posting. I was thinking of
using a red filter in my mag 3.x
skies and shooting say M42. I don't want to
deal with TP and hypering
etc so was wondering if E200 would be a reasonable
film. Scan the
image and take only the red channel, then convert
this to B&W. I hink
you would end up with a decent looking B&W
which one can do from the
backyard.
I'm guessing a true H-alpha filter would have way
to much a filter
factor to consider film?
