it gather electro magnetic radiation from object in space and concern trites it for better observation
Telescope.
They all collect and focus light and other forms of electromagnetic radation.
Telescopes focus electromagnetic radiation for closer observation.
A Telescope uses lenses or mirrors to collect and focus light from distant objects. With the advancement in optical research we are capable to watch the stars and planets better than before. Our information about universe largely depend on telescopes.
It all depends on if the telscope is a refractor, or a reflector. Reflectors have a convex mirror that bends the reflection on to a flat mirror that angles the magnified reflection to the eyepiece. Refractors use to convex lenses that bend the image and light, magnifying the view to the eypiece.
The focus is between the two lenses, closer to the eyepiece

I believe it is so it can collect more focus light to produce a clearer image.

most telescopes are used to collect and focus on different types of electromagnetic radiation from stars. Including visible light
All telescopes collect or focus radiation in some way, because visible light is a form of electromagnetic radiation. The advantages of telescopes include being able to see things that are far away, as well as the ability to observe heavenly bodies.
For visual observation: Magnification = (Focal Length of Objective Lens) divided by (Focal Length of Eyepiece) (They have to be measured in the same units.) For prime-focus photography: (One focal-length of the Objective Lens on the film) = (one radian in the sky)
