It allows you to see objects which would normally be beyond visual range, and magnifies those that would normally be too far to see in much detail.

Why did Isaac Newton invent the telescope?
Newton did not invent the telescope, he invented the reflecting telescope. The reflecting telescope was a major improvement over the distorting refracting telescope.
What are some things Issac Newton invented and or reinvented?
Newton invented the reflecting telescope which is a a great advance over the refracting telescope. The refracting telescope distorted the image via refraction. Newton invented Calculus, which is the engine of mathematics. Newton invented lens and prisms for light analysis.
What uses mirrors to focus light from the object being viewed a refracting telescope or a reflecting telescope?
A reflecting telescope uses a curved mirror to concentrate the light from distant stars, and is a very useful technique. There are very clever techniques and technicians, which can produce a mirror perfect over all its area, to within part of the wavelength of light!! The alternative method of using a glass lens, suffers from various difficulties, such as distortion and loss of light. You do not ordinarily consider focus in an astronomical telescope, for all the stellar objects are essentially at infinity.
Is the Worlds largest telescope refracting or reflecting?
Large lenses deform under their own weight, but mirrors can be supported. Reflectors do not suffer from chromatic aberration like refractors do. Large mirrors need only one optical surface, achromats four surfaces to grind. Large, very clear lenses are harder to cast than more tolerant mirror blanks.
Why some star that are invisible to the unaided can be seen with a telescope?
Because the main function of a telescope is to make things brighter. It does thatby collecting the light from an object over a much greater area than the lens ofyour eye does.-- The lens of your eye is maybe 1/2 inch in diameter.-- The lens of the largest refracting telescope is 40 inches in diameter, so it can collect6,400 times as much light from a star as your eye can.-- The mirror of the largest reflecting telescope is 400 inches in diameter, so it can collect640,000 times as much light from a star as your eye can.

What are some of the advantages of reflecting telescopes over refracting telescopes?
Size... a reflecting telescope with the same power as a refracting telescope is much shorter. This is because, in the reflecting telescope, the incoming light is bounced off mirrors (often more than once) which means the physical length is much shorter than an equivalent refracting model.
What advantages do reflecting telescope have over refracting telescope?
One advantage of reflecting telescopes is that the mirrors can be very big. Large mirrors allow reflecting telescopes to gather more light than refracting telescopes do. Another advantage is that curved mirrors are polished on their curved side, which prevents light from entering the glass. Thus any flaws in the glass do not affect the light. A third advantage is that mirrors can focus all colors of light to the same focal point. Therefore, reflecting telescopes allow all colors of light from an object to be seen in focus at the same time.

Why do scientist prefer refracting telescope over reflecting telescope?
Reflecting telescopes give a brighter, clearer image that refraactors in many cases. Add to that the fact that refractors become very impractical with objective lens sizes much above 40 inches, while reflectors can have mirrors of 200 inches and more.

What type of telescope is most often used to view distant objects?
Reflecting telescopes are far-and-away the most common. This is because the telescope can be smaller and lighter, and because lenses always absorb a little light while mirrors can be almost perfect reflectors.
What is the advantage of using a non-Optical telescope over an optical telescope?
See things that don't shine in the visible spectrum.

What advantage do space telescope have over earth based telescope?
not affected by earth's atmosphere
