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.

Is a light telescope the same as a refracting telescope?
Not exactly. A light telescope is a telescope that catches and shows visible light. The main light-gathering piece may either be a lens, in which case you would have a refracting telescope. Or - much more common with the larger telescopes - the main light-gathering piece is a parabolic mirror. In this case, it is a reflecting telescope. The largest refracting telescope is about 1.2 meters in diameter; all larger telescopes - currently up to about 8 meters - are parabolic mirrors.
What are some telescopes names?
The two types are refractor and reflector. In a refracting telescope, the light comes in THROUGH a magnifying LENS where it is REFRACTED (bent) to focus the light into an objective lens. In a reflecting telescope, the light BOUNCES OFF a curved magnifying MIRROR , and then reflected again on a secondary mirror to direct the light into an objective lens. Among the advantages of a reflecting telescope are that in a refracting lens, the thickness of the lens can absorb some of the light, while a mirror reflects all of the light. Additionally, a reflecting telescope can "fold" the telescope into a much more compact instrument, which is essential with especially large devices. A large refracting telescope would be enormously heavy and cumbersome.
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.
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 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.
How are reflecting and retracting telescopes different?
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
Which type of telescope uses concave mirrors to increase the size of the image being viewed?
Refracting
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.
Why are most modern telescopes reflecting telescopes?
A reflecting telescope is much easier to build than a refracting telescope and consequently is much less expensive. A reflecting telescope uses a concave mirror to collect and concentrate starlight and send it to your eye, whereas a refracting telescope uses a series of lenses to do the same thing. Optical quality lenses are much more expensive (and heavier) than a well-made mirror. For a given amount of money, much larger reflecting telescope can be built than a refracting. For very large telescopes, the lenses needed would be enormous and next to impossible to make optically perfect. Consequently, most telescopes are reflecting.
Which type of telescope did Galileo turn skyward in 1610?
Galileo used a reflecting telescope. A reflecting telescope uses two mirrors, one facing the sky, and one reflecting the light from the first mirror

What is the difference between refracting telescopes and reflecting telescopes?
Hi , A reflective scope uses mirrors to focus the image and the light while a refractive scope uses curved glass lenses to focus the light and the image. Generally the reflector telescope is better for deep sky viewing and the refractor is better for lunar and planetary viewing. You can also find a compound telescope which uses both glass and mirrors which is better for general viewing.

Does a telescope use a convex lens?
Reflecting telescopes don't use lenses - they use mirrors (hence 'reflecting'). Light goes in the top, hits a concave mirror at the bottom of the tube which makes the light converge when it is reflected, then bounces back up to the top where it hits a smaller secondary mirror, where it is directed down the eyepiece. Do you mean refracting telescopes? If so then these do use lenses, the amount depends on the telescope. The most simple form has an objective lens which focuses the light, and then an eyepiece which has a lens in it to magnify the image. The objective lens is convex on the side pointing out of the telescope, and is flat on the other side.
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
Does a reflecting telescope gather light with a lens or a mirror?
reflecting telescope gathers light from mirror
Differences between reflecting and refracting telescopes?
Reflecting Telescopes -uses a single or combination of curved mirrors to bring light to a focus and make an image.
Reflecting and refracting telescope what's the difference?
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.
