Catadioptric telescope

A catadioptric telescope is a type of telescope that is different from the regular ones that you might have seen. It has a special design that helps it to see very far objects in space, way beyond what our eyes can see.

Think of a telescope as a big eye that can look at the stars, planets, and the galaxy. Just like our eyes, a telescope has a lens that helps it to see. But in a catadioptric telescope, the lens is not the only thing that helps it to see. There is also a special mirror inside, that works with the lens to give a better view of the objects in space.

The mirror in a catadioptric telescope is called a "corrector plate". This plate is a flat, circular piece of glass or other transparent material that is placed at the front of the telescope. It reflects the light coming in from space and redirects it towards the main mirror at the back of the telescope.

The main mirror in a catadioptric telescope is called a "primary mirror". It is a large, curved mirror that reflects the light further down into the telescope, where it is magnified and focused by another smaller mirror called a "secondary mirror". This secondary mirror is placed at the front of the telescope, just above the corrector plate, and it reflects the light back towards the eyepiece, where you can look through and see the magnified image of the space objects.

So, in short, a catadioptric telescope has both a lens and a mirror that work together to give a clearer and better view of the objects in space. Because of this special design, it can help you see things that are very far away and can't be seen with just your eyes.
