How is spherical aberration eliminated in a reflecting telescope?

A reflecting telescope should have a parabolic mirror in which case there is no spherical aberration. The process of turning a spherical mirror surface into a parabolic one is called 'figuring'.

What kind of telescope uses both a reflecting mirror and a refracting lens to produce wide angle photos of the sky?
A reflecting telescope has both magnifying mirrors and lenses to focus the image on the eyepiece. A refracting telescope uses only lenses to magnify and focus. A reflecting telescope can be much smaller, because the light can travel through the barrel of the telescope several times, being magnified with each reflection. This is why most large modern telescopes are reflectors.
What type of lens does a reflecting telescope use?
A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.
What is the purpose of the newtonian reflecting telescope?
Gathering and focusing light from distant objects.
What kind of telescope focuses light through a transparent lens?
An optical telescope (as distinct from, say, a radio telescope). It's possible that the answer was intended to be "a refracting telescope" but reflecting telescopes use lenses as well.
What kind of shape is the primary mirror of a reflecting telescope?
The name of this type of instrument is derived from the fact that the primary mirror reflects the light back to a focus instead of refracting it. The primary mirror usually has a concave spherical or parabolic shape, and, as it reflects the light, it inverts the image at the focal plane.
Is the difference between a refracting telescope and a reflecting telescope?
A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
A telescope that suffers from chromatic aberration and has a low light gathering power is most likely?
a. a small diameter reflecting telescope.

Why does a reflecting telescope have no chromatic aberration?
There's no aberration with the main MIRROR of the telescope, because light doesn't go through the mirror. A reflecting telescope will have SOME chromatic aberration, because every reflecting telescope has at least one refracting lens; the eyepiece. Light goes THROUGH that lens, and light passing through the glass lens will generate some chromatic aberration.

What type of mirror is at the end of a reflecting telescope?
A parabolic mirror, usually. A spherical mirror is also sometimes used, but that requires additional corrections in other parts of the telescope.
What is meant by spherical aberration of a telescope?
When the image that you see is distorted because light is being refracted throught the very edges of the lens and not converging where the light refracting from the centre of the lens is.
Why did isaac invent the reflecting telescope?
== == Newton did not invent the reflecting telescope. The first reflecting telescope is credited to Niccolò Zucchi in 1616. In 1668, Isaac Newton made significant improvements to the design resulting in a much improved reflecting telescope that still bears his name, the "Newtonian reflector." He did it because the refracting (lens) telescopes of the day suffered severe color aberration. (Different focal lengths of different colours of light resulting in a blurred image because all the colours can't be brought into focus at the same time.) Reflecting telescopes do not suffer from color aberation and Newton's improvements made them effective observing instruments. Although the colour aberration of refractors was partially solved by the invention of the achromatic lens in 1733 Newton's design remains in use to this day.
Who made use of the reflecting telescope?
Isaac Newton invented the reflecting telescope.

Why did Isaac Newton invent the telescope?
Newton did not invent the telescope, he invented the reflecting telescope. The reflecting telescope was a major improvement over the distorting refracting telescope.
What type of telescope is hubble space telescope?
