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.
