What is a reflector that uses a secondary mirror to reflect light to the side of the telescope called?
LooneyTunerIan
The small mirror is a plane one reflecting a bundle of rays to the side of the main tube. That is a Newtonian reflector.

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 is the telescope for looking at the sun called?
Usually it's simply called a "solar telescope, but there are other names such as "helioscope" (specialising in sunspot observation).
What is the name for the ability of a telescope to collect radiation from a star?
Please refer to the link below. This will take you to a web site that discusses this. Multiwavelength astronomy is dedicated to observing the various spectrums of radiation emitted. That is called its light gathering ability. The 'aperture size' determines the amount of light (radiation) a telescope gathers This site might help you obtain a more in depth answer imagine.gsfc.nasa.gov IT IS CALLED "LIGHT GRASP" in an optical telescope and "RF GAIN" in a radio-telescope.
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'.
When you use a radio telescope what happens?
You are receiving that portion of the electromagnetic spectrum that radios use. It is a much lower frequency than visible light and can detect things that glow at much lower temperatures than stars ... such as gas clouds Many radio telescopes use the 'hydrogen line' at a wavelength of 21 cm. That is one of hydrogen's spectral lines, corresponding to a transition between two high energy levels in the hydrogen atom.
What is a reflector that uses more than one secondary mirror is called?
Reflector telescopes are cheaper to make than refractors of the same size than passing through it, only one side of the reflector telescope's Often a secondary mirror is used to redirect the light into a more convenient viewing spot.
What are the lenses called in a reflector telescope?
The lenses used in reflector telescope is the concave lens.
What kind of telescope is the hubble space telescope?
The Hubble Space Telescope, or HST, or just the "Hubble" for most folks, is a Ritchey-Chrétien reflector telescope. It has a primary mirror to reflect and focus the incident light. A link is provided below.
What type of telescope is the hubble telescope?
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.
What telescope collects light with a mirror?
The type of telescope is called a reflector. There are multiple subtypes of reflectors like a dobsonian, newtonian, RC, etc. Check out my youtube video on how to work with pictures taken from a telescope. youtu.be/M7-vLeVhM9g
Telescope collects and focuses light using a mirror?
Yes, or lenses. Called reflector and refractors respectfully.
Arecibo radio telescope is laid out like which optical telescope design?
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.
Are there any problems in using a Reflector Telescope?
Generally instead of looking along the axis of the telescope as is done with a refractor sighting the object to view is more difficult since you view the eyepiece at right angles to the main axis of the reflector. The main way to overcome this is to make a hole in the centre of the mirror as is done in the Hubble telescope and view the image from behind the mirror. This is called a Cassegrain configuration.
What are some types of telescopes?
there are two main types, all though there are five in total. the first one is called a refractor telescope, which uses a lense to bend the light into an eyepiece. these tend to fog up in winter time but give accurite pictures. a reflector telescope uses two mirors to reflect the light into the eyepiece. you can make these as big as you want and they dont fog up, but the immage can be distorted if the mirror angle is off by the slightest degree. of the two, i would say that the reflector is better than the refractor.there is a limmit to the size of the refractor.
Why you are using parabolic shape for radio telescope?
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.
What does a telescope reflect?
A reflecting telescope is an optical telescope which uses mirrors to bring the light to a focus. The first one was designed by Isaac newton.
What type of lens are used in telescope?
i do not know and i don't really care no ifence
