10 year old beginner buying advice

Key thing as others have said is to avoid the "kids" type scope as this will be little more than a toy and could actually put a kid off astronomy.  Proper astro gear retailer is where you want to buy.

I have the same, a 100mm f/4 Newtonian...

...a Zhumell Z100, albeit off its original, Dobson base. 

That at 13x, and as a marble floating in the aether.

I bought it for myself, in the hopes of encompassing the galaxy in Andromeda, at 12.5x.  As an adult, I think, I regard it as a specialty, for the lower powers, astrophotographic even at f/4, not a general-purpose.  A telescope needs at least a 600mm to 650mm focal-length for a sporting chance at being an all-rounder.  Those first starting out tend to gravitate towards the brighter fare, the planets in particular, which require a longer focal-length, to perhaps see them as they truly are.

That one may require someone older, to help.  Please, help me.

This one would be most enduring...
