Light from the stars they orbit makes it difficult to see them.
Planets are considerably smaller than their parent stars, also they emit no light and are very close to the star. With all this combined, separating between the two with a telescope is very difficult.

They can't. The universe is only about 13 billion years old. If there are galaxies a trillion light years away their light has not reached us yet and due to the expansion of the universe, never will. At the edge of what we call the observable universe we cannot make out individual stars, but we can detect galaxies using infrared telescopes.

Its simple! They use telescopes instead!
To - minimise the distortion of the received image due to light pollution.

extra solar planets are not bright compared to the stars they orbit
noting
By using very powerful telescopes to scan the sky.
