I think I've got the location of the background image (minus the moons) pinned down pretty well. The mountains line up "just right" in a fairly small area within a few hundred yards of 46°29'29" N, 12°26'58" E. You can visit there in Google Street View and look toward the southeast to see the mountains in the background in the image. And if you set Stellarium (e.g.) for that location at the right time on various dates (naturally there's a trade-off between dates and time), you can get the sky background aligned about right. Here are some images of the mountains and sky and a comparison... Just in case anyone is still puzzling over this one.
Did anyone work this out yet: based on the constellations visible in the better copy of the montage, what is the apparent diameter of the Moon (in the montage)?
And what about the star at the top of the teapot in Sagittarius (lamba Sgr). Do you see it in the montage? Half of the teapot is visible on the lower right. The lower half is behind the mountains. Anything unusual about that star??
