Hi Tasview..
..
My first t'scope was a Tasco 114 on an EQ mount & luckily I bought it in time to see the impact sites that comet 'Shoemaker-Levy 9' made in/on Jupiter in 1994.
Your t'scope is more than capable of seeing a multitude of objects in our night skies. Just don't try to overpower the 'seeing conditions' when using the 4mm E/Pc.
Enjoy it with your son.
