Actually, I haven't pushed this film yet. Most of the time I've used it has
been under less than ideal skies, with some light pollution. So my resulting
slides weren't really dense.

I've seen some pushed 400F results from Stephen Pitt, and they looked pretty
good. I believe he had been shooting at a good dark sky site. I fact these
results *may* have helped the red response of this film. That's been
something I've wanted to check out, if I can get to a dark site (with clear
skies<g>) this Spring/Summer. I have been planning on a +1 push next time I
shoot it from a dark site.

Perhaps Stephen will chime in here and give us his opinions on pushing this
film.

I did give a short hyper to a roll last Summer, 1hr @ 50C with a hand pump
setup. Unfortunately haze and fog came in during the test exposures. I've
had an unbelievable streak of bad luck with weather conditions since about
April of last year ;o(

I think it may need repeating that those who are used to E200's incredible
red response are probably going to be disappointed with 400F on the fainter
emission nebula. With it's strong blue response, I originally was touting
this as a great film for galaxies. Time has shown that it gives fine results
on the brighter emission nebula also, but E200 remains a top choice for many
faint objects. Jon Kolb has some nice results where he used E200 for the red
channel; and 400F for the green and blue.
