   Yup - unfortunately I don't have one. I get around that since 
virtually everything I do print-wise these days are run thru the computer
and thus I can crop the images and adjust the stereo window. I do have
a tendency to move too much and get hypers, though.

   I think the problem from the shoot last night will be the moonlight.
It was pretty clear. At this elevation, on full moon (especially with
a lot of snow on the ground) the sky is visibly blue even at night
with the right weather conditions - (which people don't believe until they see it). We normally don't have much air/light pollution (some, to be sure) but
I generally can walk out on my back doorstep and see the Milky Way without
any eye adjustment time from a fully lit house. I couldn't do that even
in Flagstaff. Of course the town is 4 blocks wide and 6 blocks long 
without any great amount of outdoor lighting (generally not allowed due
to the fact that it's a National Historic District). Streetlights mostly -
no neon advertising signs.

  Yeah - I was thinking of maybe trying 400 this evening, but it looks
like it might be moot since the clouds are starting to build in :-(.
So my next chance would be back in Texas, and *there is* a problem 
due to the light pollution of Dallas 30 miles off to the west and
the 150% humidity (only a slight exaggeration). 

Thanks to everyone who has made suggestions. IF anything turns out,
I'll stick 'me on the web site.

THANKS
