Cylindrical
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.
its those telescopes with an image at the end. you turn the end and the images changes shape. usually given to children to play with.
The aperture of the main lens or mirror, which also determines the light gathering power ------------------------- True but the quality of the mirrors or lenses (how near they are to a perfect shape for the design of telescope) determines the sharpness of the image.
an artificial telescope is a telescope that is man made by people from NASA or anyone who can make a telescope
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.
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.
