Re: [APML] Provia concensus roundup

["Leslie/Joe Schaefer" <schaefer@htva.net>]

Hi Herm,
 I tried shooting galaxies with E200 using my Celestron C11 with GEG focal
reducer (f/6.5, FL/1825) and even at 120 minute exposures the images were
always under exposed so I started using Provia 400F. With the faster film
speed I started getting much better results.
 I also have my Provia film pushed +1 stop. Due to bad weather I only have
three good example using this film. My exposures range from 42 minutes to
120 minutes. I guess the bottom line for me is that if I'm going to shoot
galaxies I prefer Provia 400F over E200. I hope this helps.
