I know there are some star-gazers here from previous threads. I'd like to get a telescope for Christmas for two brothers, one is about to turn 11 and the other is 7. A quick look on Amazon shows quite a few in the $60-120 range, or even below. Celestron, in particular, has a lot of models; some are long and thin, others are shorter and wider - I really have no idea what the differences are. I'm happy with that price point, but I'd be ok with spending a bit more if it gets a significant upgrade in capability and/or durability. Chances are they'll stick it in the garage, but on the off-chance that one or both becomes interested in astronomy, I'd like it to be good enough that they don't have to upgrade for a while. Any suggestions?
