Thanks for your StringJunky for your explanation I will take into consideration what you said and make a decision
Sensei, I have no specific budget.
just trying to purchase something "as good as it can be, with the least I can spend on it"
obviously, I'm not rich.
so, there is a limit in what I can purchase.
say... 2000 USD would be hard to explain to my wife.
and would be too expensive to let my child to use. LOL
but I wouldn't like to have a cheap thing that can't see even the moon clearly and might break up on the third time we use it.
computer controlled ones, aren't more expensive?
I mean, it would be easier to find something to see, since I believe can have some programs or coordinates of stars or planets.
