Thanks for clearing that up Patrick. I was totally confused when they said they couldn't do push processing back in October. I may send my next roll of film up to Salt Lake to Borge Anderson. We have friends who routinely go up there. I'm beginning to get the hang of tracked piggy-backed astrophotography. However, I'm going to get into digital astrophotography as soon as I get a telephoto Canon EOS lens. The digital camera is blind to the h-alpha wavelengths so I'm still going to take slides with either E200 film or Fuji Sensia 400 film. I can't afford to replace all my lenses yet with EOS "L" series lenses. Debbie

Hi Deb,
What you were saying just didn't make sense so I called Camera Country and talked to their E-6 guy. Turns out, what you heard from their sales person is what they tell folks taking "normal" pictures (I guess that proves the rest of us are abnormal...). We are to the right of the Bell curve in intelligence. That is what I like to think about amateur astronomers.
However, when I explained you were going to be taking pictures with exposures lasting several minutes he said that changes everything and that the setting on the camera in such cases makes no difference.
So, what you need to do is take the film in and just ask them to push it one stop (makes it ISO 400) or two stops (ISO 800).
It was kind of interesting that when I started getting into how pushing is accomplished (extending the development times) he didn't seem to know about that stuff. So I get the impression they're not really a custom photo lab, but rather there's probably some dial on the machine they use that can be set to No Push, Push One Stop and Push Two Stops. :-)
I hope this clears things up.
Patrick
p.s. Should you ever decide to try your hand at processing the film yourself, just let me know and I'll get you started. It's really not that hard and there's something to be said for showing a picture and being able to say "I shot and processed that myself".

Hi,
I just called Camera Country and found out they do E6 and push processing. I just need to set the ASA film speed to 800 for "Push 2" or set the film speed to 400 for "Push 1". Last time I set the film speed to ASA 200 and that's why they couldn't push the film. This is the way I understand it.
However, as Joe said a "Push 2" will make the film more grainer so I may just do a "Push 1" next time. According to the January 1999 Sky and Telescope issue, Ektachrome E200 pushed two stops in a good option for camera-on-tripod shots.
Thanks guys for the tip on Borge Andersen. I'll keep that in mind.
