Anyone wishing to dazzle their friends, here's what I found on @richard 's winning entry.
I know the northern sky pretty well but couldn't place the stars even when I knew, from time-lapse tracks, this was a real image and approximately where the pole had to be based on those tracks.
Then, along the very right edge my brain caught the familiar handle of the Big Dipper (Ursa Major if you like) and it all fell into place. The give-away was the double star Mizar, the middle star of the Big Dipper's handle.
Only the 3 handle stars are visible and Mizar shows its double-ness very well. Here's a Stellarium image of the Dipper oriented approximately as in the wallpaper image.
