there is none, if you see those super large telescopes, they all have huge lenses
What else can I help you with?
Why are most large telescope reflecting telescopes?
It is cheaper and easier to create mirrors rather than lenses. Large lenses become difficult to support the larger they become. Additionally, mirrored telescopes fold light waves so that a telescope can be shorter, the same size telescopes with lenses are greater in length.
Which of the following statements best describes the difference between a refracting telescope and a reflecting telescope?
A refracting telescope uses lenses to gather and focus light, while a reflecting telescope uses mirrors. Reflecting telescopes are often preferred for large astronomical telescopes because mirrors can be made larger and more easily than lenses.
What is the difference between a reflecting telescope a refracting telescope and a radio telescope?
Reflecting telescopes are usually designed to capture and concentrate light through the use of a large concave mirror which focuses the captured light on a smaller, flat mirror which in turn reflects it to the eye or a camera. Refracting telescopes use convex lenses to capture light and focus it where the eye or a camera is. Radio telescopes collect long wavelength radiation (radio waves and microwaves) and are all forms of reflecting telescope. The first telescopes were refracting telescopes, because the technology existed to form the needed sizes of convex lenses. Reflecting telescopes were developed later, when advancing technology provided the means of making very regular concave mirrors. All the largest modern telescopes are variations on the reflecting telescope design because it is easier to make and manage very large concave mirrors than it is to make lenses of equivalent light collecting power.
How reflecting telescope compare to refracting telescope?
Reflecting telescopes use mirrors to collect and focus light, which allows for larger apertures and eliminates chromatic aberration, a common issue in refracting telescopes that use lenses. Refracting telescopes rely on glass lenses to bend light, but they can suffer from distortions and are typically limited in size due to the weight and cost of large lenses. Overall, reflecting telescopes are generally preferred for professional astronomy due to their versatility and ability to produce clearer images at larger scales.
Can you see distant objects using a telescope?
Most optical magnifying units use compound lenses. Lenses that are made to focus light onto a spot or spread it out. A combination of them makes the best optics. Lenses are ground as convex and concave.

Which telescope is bigger refracting or reflecting?
"To build a large refracting telescope would require very strong supports to hold large enough lenses. These supports would tend to block out important light. So the refracting telescope is limited in its use. Today most large telescopes are reflecting telescopes." ~ BYU Home Study Astronomy course
What are the uses for a reflector telescope?
A small reflector telescope usually is less useful than a small refractive telescope, especially when there is plenty of light, but when one needs a large telescope and there is not much light, then the reflector telescope can be made much lighter than the refractor and usually much larger. It also can gather more light which is very useful in astronomy. It also does not have to pass its light through thick large lenses that absorb part of the light. What is more, it can reflect almost any kind of light, from microwave radio to ultraviolet, while it is difficult to make lenses for large refractor telescopes that do not absorb some kinds of light such as infrared and ultra violet. There also are advantages when one wants to see in more than one wavelength (colour) of light. It is difficult to prevent the different colours from separating out when passing through a large lens, but a reflector telescope does not have this problem much.
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 a refracting and a reflecting telescope?
A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
What type on telescope in the south African large telescope?
it is a reflector telescope
When was Southern African Large Telescope created?
Southern African Large Telescope was created in 2005.
What kind of telescope are most of the large optical telescope?
Reflector.
When was the very large telescope made?
The telescope was invented first in 1608.
