Gravitational Lensing

I was watching this doco on "The largest Black holes in the universe" on you tube in 480p resolution.

Telescopes....

Hey guys, my 8 year old daughter wants a telescope. She wants to at least be able to see saturns rings, moon craters, mars in any form of detail......

You can probably gather I'm an absolute novice, so thanks in advance for your assistance!!

Gary and Isabella.

Having set it up however, I am totally unable to get a focused image that's even close!
I have tried barlow lens, extension tubes in all combinations but am unable to focus right down to get a good image.
Normal viewing through the scope with eyepieces is ...
