There's enough background, extracurricular detail and technical commentary to make this more than a load of pretty pastoral-fantastical art, but it's got that going for it too.

A greatest hits of desktop backgrounds that's nice to have, even if some like the Ultra Deep Field are best served by a screen (preferably IMAX). Also a nice pictorial supplement when I get around to reading Carl Sagan again.
