Re: [APML] More aurora fun - Provia 400F +1

Bobby -
I've used it on the TV102.  Both of these are with it pushed +2:

I'm working on a NGC281 that was on the current roll with a +1 push.  I
don't know if I can save it as part of the frame has the green processing
booger in it.
At f/7 and a +2 push, my thoughts are that you should expose around 60
minutes from a fairly dark sky and 70-80 minutes in a truly dark sky.  With
the +1 push, I went 75 minutes @ f/7 from my mag 6.2 skies and the trans was
exposed just about right.
I'll continue to try the 400F into the winter.

Thanks for the nice comment on the aurora shot!

Chris
