Have an early 70's (?) model Celestron telescope with a C-90 ( the mid-sized lens on the side ?). Have absolutely NO KNOWLEDGE of telescopes, obviously. However, I CAN READ, and follow instructions remarkably well !! Just need some sort of manual, anything for basic setup. It's motorized at the base, recieves RF signal, I believe, and appears to be programmable. Any info greatly appreciated. Thanks for your time, in advance, Sheri " I WANT TO SEE STARS !!" :)
