The Diamond Temple definitely does help, at least from my experience with it, but there is also a certain amount of luck involved. If you have a Zodiac-type dragon already, breeding it with a Diamond Dragon while the Diamond Temple is active gives you a higher chance of breeding not only the Astromancer Dragon, but also the Dark Angel, Black Diamond, Gold, Mercury, Anubis and Crusader dragons. If you have the gold to spare, it might be worth a try.
Oh, and thanks for pointing that out, ciarjen! :D
