Why are most modern telescopes reflecting telescopes?
Most modern telescopes are reflecting telescopes because reflecting telescopes are generally more cost-effective and easier to build at larger sizes compared to refracting telescopes. Reflecting telescopes also suffer less from chromatic aberration and can have a simpler design with fewer optical elements.
When was the day Sir Isaac Newton made the reflecting telescope?
Newton did not invent the telescope. The first practical telescope was made by Hans Lippeshey and Zacharias Janssen in 1608 in the Netherlands. Galileo made significant improvements the following year. All these early refracting telescopes suffered from big problems with chromatic aberation, the separation of colours.The first reflecting telescope is credited to Niccolò Zucchi in 1616. In 1668, Isaac Newton invented a much improved reflecting telescope that still bears his name, the "Newtonian reflector." He added a smaller "diagonal" mirror near the primary mirror's focus to reflect the image at a 90° angle allowing him to look through the side of the telescope and see without blocking the incoming light.Nice answer upstairs! Newton made his first "good" reflecting telescope in 1688. It still exists -- and works!
Why are most large telescopes reflecting telescopes?
They are refracting telescopes(:Large refracting telescopes are no longer built because there were too many problems with them. There was color distortion, light pollution, and when the object hits the focal point it turns upside down. Then you don't see the object for what it really is, you see it upside down and weird-ed out. They are to complicated and scientists believed they should just stick with the simple, small, original refracting telescopes!!!!-Meghan Betts (8th grader)
Advantage reflecting telescope over refracting telescope?
Reflecting telescopes are typically more cost-effective to build for larger apertures compared to refracting telescopes due to simpler construction and fewer optical components. Reflecting telescopes do not suffer from chromatic aberration like refracting telescopes, leading to sharper images with better color accuracy. Reflecting telescopes can also be made with larger apertures, allowing for better light-gathering capability and higher resolution for astronomical observations.
What type of optical telescope has the potential to be made largest in power?
For amateurs, reflecting telescopes (with one parabolic and one flat mirror) can be made cheaply at very large sizes. For example, a $3000 telescope with lenses might be 4 inches wide and one with mirrors might be 16 inches wide. This also makes it possible to build massive reflectors for research purposes, like the planned 38-metre-wide E-ELT.
Who built and used reflecting telescopes?
Thousands of people still do build their own astronomical telescopes; it isn't that hard to do.

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
How old was James Gregory when he invented the Gregorian telescope?
James Gregory was 25 when he published the design of the telescope that has come to be named for him, the Gregorian Telescope. He never build one. The first one built was make by Robert Hooke ten years after the design was published, and after Isaac Newton built his Newtonian Telescope. Both were reflecting telescopes.

What advantages do reflecting telescopes have over refracting telescopes?
refracting telescopes use lenses instead of mirrors. 1. chromatic aberration: when light passes through a lens it is focused at different points. Blue focuses closer to lens and red farther creating a smeared image. 2. Some light is absorbed by lenses. 3. Lenses are heavy and can only be supported by the edge. 4. Lenses must have to optically acceptable surfaces whereas a mirror only needs one.
Why do reflecting telescopes cost less than refracting telescopes?
The objective lens of the REFRACTING telescope has to be a single gigantic piece of perfect glass.The light being observed goes all the way through it, so any imperfection anywhere ... on either surface oranywhere INSIDE it ... can affect the quality of the image. It also has to be totally stable and rigid, sinceit can only be supported around the edge.The mirror of the REFLECTING telescope only has to have a perfect SURFACE. The light hits the surface andbounces off of it, so nobody cares what happens behind the surface. The mirror can be made of two-by-foursor old crushed beer cans, and it can be supported by a solid rigging of carpenter's scaffold. Just as long asit has a perfect front surface, we don't care.For any large size you want for the objective element ... large enough to be attractive as a muscularastronomical instrument ... it turns out to be much easier and cheaper to build a parabolic mirror of thatsize than to build a perfect lens of the same size.
