Thank you OP, and all those that contributed to this "Great Post". A true insight into our home in the Milky-Way galaxy.
... The thing that makes me wonder is "how" did the old ones get all there idea's? They didn't have light pollution, I don't think. And as some have said, from a dark sky there are so many stars that it is hard to pick out constellations. Orion is just a bunch of stars. Bright stars that make a pattern that is one of the most reconized. I'm sure that (I know) all them stars are not all associated with each other.
They didn't have light pollution but they had the moon, and in a moonlit night, even with great skies, only some asterism standout. To them stars were fixed on a sphere,there were no distances, and maybe they just named the asterisms after things that were significant to there life's, like the hunter, the water bearer, the bull, the ram, etc.
Until recently the only asterism I knew was a trapeze with 3 stars on a diagonal that I called "the 3 Mary's", now I know it's part of the Orion constellation. When I was 12 years old, and men went to the moon, I started wondering about the universe and how it would be like to see it from the outside, and how far out would I have to go, knowing it was impossible due to its infinite size.
As a beginner (2007), I obviously started with the constellations, as a road map of the sky in medium polluted skies, it works well. Anyway I feel the need know more about the relative position of the solar system plane and the galactic plane and how objects fill the space around us.
I support the idea of OP, of creating new maps of the sky with more 3D and galactic information.
It is fun to look at distribution of open clusters along the galactic plane vs the globular clusters on Hayden Digital Universe. Although I new that, its hard to see it on the charts.
I'm having a lot fun with the Hayden Digital Universe, great perspectives from within and the outside Milky-way (just starting to use it).
