This is a very beautiful picture. We may note that, unlike other pictures taken of this area, this one has been made with a technique that doesn't emphasize the bright stars. That makes it harder to pick out the constellations, but you can more easily see some other features.
One of the easiest deep-sky objects in this picture is the North America Nebula, right above the most obvious "mitten" formation on the ground. Just above the North America Nebula (but not "touching" it) is Deneb, the alpha star in constellation Cygnus.
To the left of the North America Nebula and Deneb you can see a very dark patch, and to the left of that is a rather faint pink region, seemingly with an arc-like "string of pearls" in front of it. This nebula ought to be IC 1396. On the other side of the North America Nebula, to the right of it, are the pink patches of the Gamma Cygni Nebula.
At the "top" of the Arch of the Milky Way is a strange bluish "hook" attached to a faint "line". That is actually the Coathanger asterism!
Towards the lower right part of the Milky Way arch, you can see yellowish patches peeking out. They are parts of the Milky Way bulge. The first really bright such yellowish patch (seemingly crossed by a "line" of stars) contains rich open cluster M11, although I can't pick the cluster out myself.
Inside the next "yellow patch", you can see two brightenings, one of which ought to be star cluster M25. Above them are three pink emission nebulae. The first, diffuse one is probably NGC 6604, the second one is M16 and the third one probably M17.
You can see slightly "plume-shaped" star cloud M24 sitting right in the dark dust lane of the Milky Way. Below M24 is an "arc" of stars, and below that is the Trifid Nebula and the pink Lagoon Nebula. Below that is the bright yellow "Sagittarius star cloud", the optically brightest unobscured part of the bulge of the Milky Way. Above it, on the other side of the Milky Way dust lane, is the large dark Pipe Nebula. One dust lane emerges from the Pipe Nebula, rising and turning to the right, ending at the Antares and Rho Ophiuchi region.
To the right of the bright yellow Sagittarius star cloud (also known as Baade's Window) is anothe ryellow patch, this one with an obvious white, grainy center in it. The white grainy patch is star cluster M7. Above it, inside the dark dust lane of the Milky Way, you can see an elongated patch, which is star cluster M6.
Finally, on the far right you can see an elongated feature. At far left this feature is pink from emission nebulosity, but farther right it turns into what looks like a series of star clusters. This is star cluster NGC 6231, supergiant Zeta1 Scorpii and related nebulosity.
As I said, this is a great picture! I agree that there is something otherworldly about it. It does look like a good landing site for UFOs!
