How to use "telescope" in a sentence

I saw Captain Nemo looking through a telescope at something far away

I had a small telescope with me, so I put it up to my eye to see what he was looking at

At that moment, I felt a strong hand knock the telescope away from my eye.

Looking through the telescope, I saw a circle of deep blue with the little round planet in the centre

Thick clouds of smoke or dust, which looked like little grey, moving spots through a powerful telescope on Earth, spread through the clearness of the planet's atmosphere and hid its more familiar features.

Suddenly, I remembered the night I had watched through the telescope.
