The shot on my web page is not pushed, or I would have noted it. I've
used the stuff unpushed and pushed one stop, and haven't noticed any
problems with grain either way. The only time I push it is when
shooting at f/7.9 through the TMB152, in order to keep the exposures
shorter. At f/4 through the Borg, it's just as easy to go another 10-15
minutes. On bright subjects (Rho isn't one of them!), 15 minutes at f/4
will record an amazing amount of nebulosity on this film.
Sincerely,
Jon Kolb
