A telescope won't help you with astrology. You'd be better off spending that grand on a top quality crystal ball, some tarot cards and a ouija board
Seriously though, $1000 will get you an awesome 12" Dob, or a very small goto scope, or a 8-10" Dob with push-to. You'd need to buy the scope and the push-to computer separate and put them together yourself. Others on the forums have done that w/o much difficulty and I'm sure they'd be happy to help you with more specific advice.
