Thanks for the links. I usually prefer negative film but it looks like a
good one might not be available. I guess I would have to use 100 speed slide
film and push it.

Why not use E200 4x5?
E200 is available in all formats and is a proven astrophotography
film........it's only shortcomings are less blue sensitivity and perhaps too
much red than we would like.
It can also be easily push processed up to about 3 stops, although I think a
1-2 stop push is all that is usually needed. This will render the sky
background (depending on skyglow, etc.) grey instead of black, which is
better for scanning.
