The
Entire Milky Way
Horizon

Uploaded 7/11/06
During our
recent trip to Queensland Australia to visit with our good friend
Paul Tierney, we had many opportunities in the superb skies found
deep in the Outback for both imaging and visual observing. While
at our darkest site near Winton, the full Milky Way was photographed
with the robotic barn door mount using multiple exposures and
the 17-40mm L lens set for widest field. The image presented
here is the final panorama, extending from the roof of the sheep
shearers quarters on the left, to the distant horizon with a
few trees on the right.
The most detail
is in the largest image, if you have a faster connection.
Image Details:
The center of our
galaxy in Sagittarius passes through the zenith from this location,
which is the brightest part in the center. The dark rifts that
appear in front of the galactic plane are unilluminated dust,
which blocks the stars behind and are tinted a dull brown in
color. I wont try to list all the deep sky objects you can find
in this image, but the Coal sack and Eta Carina are on the right
side above the horizon, to the right of center is the dark constellation
of the Emu. The full extent of the "Dark Horse" nebula
is just above center. You can see a bright pink spot to the left
of center, thats M8 - the Lagoon Nebula. The richness of the
Milky Way diminishes slightly on the left side, into Aquilla
and the left edge is Cygnus. Look carefully at the lower left
corner, and you can see all of Delphinus.
