There's a link to an article about the photographer, Wally Pacholka.
Interesting.

Subject: Re: [Texascavers] Cave photo
From talking to someone here at work that does a lot of
astro-photography, he said that Milky Way image is easily less than a
minute exposure, given really dark skies.
However, he also states that the cave image was probably overlaid from
a 2nd exposure, otherwise you would likely have some movement
indication from inside the cave.
Either way, its a beautiful picture.

Hey Bob--
Cool photo....but I wonder if photo shop was involved. If you took an
exposure long enough to get that type of detail in the Milky Way,
wouldn't
you get star streaks from the Earth's rotation during the long exposure
time? Any astro experts out there with an opinion? Or half-astro experts?
