A kaleidoscope.
The Arecibo radio telescope is not laid out like any specific optical telescope design. It is a unique design called an "active spherical reflector" where the dish itself is spherical in shape and fixed in position. This design allows for a large collecting area and a high sensitivity to radio signals.
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
The sharpness of images in an optical telescope is often associated with its resolving power, which is determined by the size of the telescope's objective lens or mirror. A larger objective size allows the telescope to collect more light and resolve finer details in the observed objects.
A curved mirror is used to focus light in a reflecting telescope by reflecting and converging the light rays to a focal point. This mirror can have a concave shape to collect and concentrate light towards the eyepiece for observation.
It is a paraboloid, which focusses the light from a star down to a single point which can then be looked at through the eye lens or eyepiece.
you look in a telescope and see if they make a shape
A parabolic shape is used for all reflecting collectors ... visible light telescope, radio telescope, satellite receiver, etc. A parabolic reflector directs all parallel incoming rays toward one point, called the 'focus' of the parabola.
The lens is a convex shape which allows it to concentrate and magnify light which passes through it.

It's not that the sun's shape doesn't change - it's held in a roughly spherical shape by its own gravitation and rotation, but any variations would be so small that we wouldn't be able to see them without a telescope.

Refracting telescope: Brings light to a focus by passing it completely through a transparent glass lens.The lens must be perfect throughout, and unobstructed.Reflecting telescope: Brings light to a focus by reflecting it from the surface of a curved mirror.The surface shape must be perfect, but the mirror may be made of anything, and can be supportedby anything.
