All I can say is that the density on the slides was excellent. The site had an
extremely dark sky, and ISO 100 film is obviously pretty slow.
If you shoot star trails from a suburban site, you may have to stop down to as
much as f/11 on ISO 100 film for an all night shot.
I recommend Provia 100F film.
