Explanation:
The photographer had this shot in mind for some time.
He knew that
objects overhead are the brightest --
since their light is
scattered the least by
atmospheric air.
He also that knew the
core of our Milky Way Galaxy
was just about straight up near midnight around this time of year in
South
Australia.
Chasing his mental picture, he ventured deep inside the
Kuipto
Forest where tall
radiata pines
blocked out much of the sky -- but not in this clearing.
There, through a window framed by trees,
he captured his envisioned combination of local and distant nature.
Sixteen exposures of both trees and the
Milky Way Galaxy were recorded.
Antares is the bright orange star to left of
our Galaxy's central plane, while
Alpha Centauri is the bright star just to the right of the image center.
The direction toward our
Galaxy's center is below Antares.
Although in a few hours the
Earth's rotation moved the
Galactic plane up and to the left -- soon
invisible behind the timber,
his mental image was secured forever -- and is
featured here.
