The Large Sagittarius Star Cloud
One of the
most profound things any human being can see is our own Milky
Way Galaxy. For the best view you need to be hundreds of miles
from any large city, and preferably tens of miles from any small
town. Such places are increasingly hard to find, especially in
advanced nations like the USA where "progress" includes lighting
up the sky and blotting out our view of the grand reality
beyond.
Capitol
Reef National Park in Utah is one such sanctuary of the night
sky. During my recent assignment as a Night Sky Volunteer in
that park I took advantage of those pristine skies to do some
wide-field astrophotography.
This is a
cropped closeup of the brightest part of the Milky Way. This is
part of the galactic hub, the inner region where stars are more
tightly packed than they are in these outer regions, and much
older as well. These stars are so dense and distant that even a
large amateur telescope is unable to resolve them all. Much of
the fantastic intricacy of the dust lanes riddling this area is
visible through a good telescope. Numerous foreground clusters
and nebulae dot the region. Here we are looking through an
immense corridor of stars.
I shot
this with my 85mm f/2 lens stopped down to f/4. The individual
exposures were 2 minutes at ISO 1600.
