This is "The Dawn's Left Hand" is it not? Of Omar the Tentmaker & Edward Fitzgerald?
of
Dreaming when Dawn's Left Hand was in the Sky
I heard a voice within the Tavern cry,
"Awake my Little ones, and fill the Cup
Before Life's Liquor in its Cup be dry."

Does seeing that the Zodiacal Light and the Milky Way band are almost parallel in this photo mean that the Solar System is moving around the Galaxy edgewise?

I confused , , the text says that this light is seen during this time of the year, and from the Northern Hemisphere -- then it says the picture was taken in June (it's now almost November) and the picture was taken in Chile .... What am I missing?

If you believe Wikipedia, it says that
plane of the Milky Way is inclined by about 60° to the ecliptic (the plane of the Earth's orbit), http://en.wikipedia.org/wiki/Milky_Way
I've read 58 degrees elsewhere but I cannot find a reliable citation at the moment. I'll edit this post if I find one.
