Hi Matt,

I share criteria with Bill Barber, Mike, Adam and hope not forgetting
anyone.

030529a01.jpg is a great work both photographic and javascript.

I can say I did a little step on this direction. Both exposures came out
right from first attempt.  Some two or three years ago in the middle of a
field during a very rare moonless pristine night, with a very very rare low
humidity where I live. No trouble with dew. Equipment was OM 2 on auto mode
exposure compensation +2 I think, Zuiko 21/3.5 @ 8 on Slik 212 tripod, E100.
I got bored waiting for the camera decision to close the shutter. Of course
it's 90 degrees angle of view, not 180. It's a pitty we don't have a North
Star here, this only fact could have made me buy a Zuiko 18 or 16 mm (why
Tamron).

What I cannot figure out is how did you manage not to overexpose the
foreground objects. Maybe because they're red (why red_please), but I saw
another picture in your site -8 hours exposure, must have been during
winter- with common buildings in the foreground and they were not
overexposed. I got a little overexposure on this situation, and remember to
have +1 compensation only. Maybe I should have trusted the circuitry better.
But again, the trees were heavily iluminated with a mercury lamp.

Since I was a child I thought Nuevo Méjico was a great place to visit.

Rgds,

Fernando.
