Well, DD and I went to our first astronomy club meeting last night. Wow, was it was a lot more interesting than I thought it would be. DD thought it was the best thing ever- Jupiter and three of it's moons were the focus of everyone. And since she was by far the youngest she received a lot of attention. One person even gave her a book on all the planets and many of the stars. Another told me of a link that had real time star charts and recommended several computer programs that would be good.
Anyway, there were a lot of really impressive telescopes out (and some junk ones too). I spoke with the man that runs the astronomy club for kids there. He (and many of the other chimed in with the same recs) said to start with stay away from any telescope that you can purchase from wal-mart, target, etc (the junk ones that the owners there even admitted were junk).
The ones mounted on the tri-pods are not a good choice for kids. Unless you spend a lot of money the tri-pod is not stable enough. Between the possible wind and the kids bumping into it while they are trying to look, they will not be able to see much for long.
They did recommend the Dobson type telescopes as a possibility.
Their biggest recommendation was the Edmund's Scientific Astroscan.

I almost laughed when they showed me several. There were actually 5 of them! and they look nothing like a telescope to me. I tried one out and it did turn out to be pretty neat. It looks a little like a beaker to me and sits on a swivel stand. There is a strap for the kids (or adults) to carry it with and it was pretty light. They said that it was a great beginner telescope because the mirrors are fix mounted and apparently won't move with the telescope is jarred. Everything is internally mounted and a whole bunch of other pluses that went right over my head

. They also said that it was a really good scope to use until she was old enough to purchase her next telescope herself
Another good place to purchase a scope is through an astronomy club. None of the members there last night were selling any, but they said that someone is usually upgrading most of the time.
