A reflecting telescope.
This type of telescope is often referred to as a Schmidt-Cassegrain telescope, and can be short and wide. They have an eyepiece that extends at a right angle from the body, and have a disk in the middle of the lens, behind which is the mirror.
A concave mirror will tend to "focus" light to some degree, depending on the curvature of the mirror. A parabolic mirror will bring reflected light to a sharp focus, and telescopes use this type of curve for the shape of their reflective surface. And for exactly the reasons you think they do. Want links? You got 'em....
The light or image is focused at a different position relative to the real position of the emitting light. This is dependent on the type of lens.
Real image
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.

radiotelescope
Optical!!
The Hubble telescope was a basic reflector telescope with a 94.5 ft mirror. The Hubble collects light though its open end, the primary mirror reflects the light to a secondary mirror that then reflects the light through a hole in the primary mirror to a focal point of the instruments or eyes of the Hubble.
Yes, a Hershelian telescope is a type of reflecting telescope in which the primary mirror is tilted so the observer's head does not block the incoming light.

The only type of thing that telescopes gather is light! But from the characteristics and position/s of the light/s we may infer great things.

A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.
A parabolic mirror, usually. A spherical mirror is also sometimes used, but that requires additional corrections in other parts of the telescope.
