I never thought I'd be able to do this! Attached are my first successful hand-held (!) astrophotographs taken with the Lumia 920. The constellation Orion is in the center, with the moon (rather overblown!) near top right and Jupiter at its 2 o'clock position.
The second shot is a crop of the first, and shows Orion alone. Note the middle star in Orion's 'sword' - that is the great Nebula in Orion. Yes, that's right, I took a hand-held photograph of a freaking NEBULA with my cell phone!
