Hi Roger:
Nice exposure, and as Matt pointed out, it shows that moonlight has the same
color as daylight. The little jog in the star track is a problem, but
compared to some of my early efforts, this is great! Did you take any much
longer exposures (to get longer trails)? You would have to use a much
smaller aperture to avoid over exposure, but one- to four-hour trails are
quite nice. I have a couple from my backyard that I'll have to put on the
website. Needless to say, my backyard doesn't compare to the observatory
dome in your shot!
