I would stay away from "coated optics" binos for astronomy. "Fully coated" is passable, but "fully multi-coated" (FMC) is what you really want. The improvement in brightness and contrast from "coated" to FMC is awesome. The Chinese binos sold by AOE come with very good full multi-coatings and at those prices there is really no need to go for any lesser coating IMO.
