In a reflecting telescope the objective is a?
mirror with a concave parabolic figure
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 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.
Which type of telescope uses a mirror to gather light?
A reflecting telescope.
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 type of telescope uses lenses or mirror to gather and focus energy?
the reflecting telescope uses mirrors and lenses. The refracting telescope does not include the mirrors.
Does a reflecting telescope gather light with a lens or a mirror?
A reflecting telescope gathers light with a mirror instead of a lens. The mirror reflects light to a focus point where the image is formed. This design eliminates chromatic aberration that can occur with lenses.
What is meant by the size of a telescope?
The size of a telescope almost invariably refers to the size of it's objective lens, or mirror. It translates to how much light the telescope can gather, not "how big it can magnify", which is very secondary.
Does a reflecting telescope gather light with a lens?
No, with mirrors; but there are lenses in the ocular that do gather the light from the mirror and make an image you can see with your eyes.
Does an Orion 6 inch deep space explorer dob have a parabolic mirror?
Yes. Specifically, it's an f/8 parabolic mirror.
What does the light gathering ability of a telescope depend on?
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.
How does the reflecting telescope work to gather and focus light from distant celestial objects?
A reflecting telescope uses a curved mirror to gather and focus light from distant celestial objects. The mirror reflects the light to a focal point where an eyepiece or camera can capture the image. This design allows for larger and more powerful telescopes compared to refracting telescopes, which use lenses.
