The second one is really cool, but clearly photoshopped, way beyond what I'd consider acceptable for a "photo"... therefore I wouldn't call it a photo so much as digital art.
Unless of course the photog used a super telephoto lens of a faraway tree but somehow it was wide enough to include the north star and he used some trippy dealio to freeze the moon while star trailing the sky...
Come to think of it, that could be done as a double exposure...
