Question
‘m interested in building and designing a reflector telescope…but first i think it may be better if i knew how the work… so does anyone know how a reflector telescope works… (the optics stuff and what kind of mirrors are used etc.)

In a reflecting telescope a concave mirror (the “objective”) brings light rays from the subject to a focus; the mirror is usually ground to the shape of a parabola. Great precision is required for a good image; many mirrors are figured to within 1/20 of a wavelength of light; a very small error indeed. A small lens (the “eyepiece”) magnifies the image and projects it into the eye of the observer. A classic “Newtonian” reflector (named for Issac Newton, its inventor, who conceived of the reflector as an alternative to the refractors of his day which suffered from enormous color distortion) uses a small flat mirror to reflect the light from the objective to the eyepiece on the side of the telescope. Other arrangements direct the light out the back of the telescope through a hole in the center of the objective. See http://www.cogent.net/~pyrrho/basics1.htm for a very nice explaination of the different types of telescope, and some illustrative diagrams. You should know that grinding a telescope mirror is a time consuming, demanding, painstaking undertaking. Many ATMs (Amateur Telescope Makers) buy factory-made mirrors to incorporate into their telescopes. Sources of such mirrors abound, but good ones aren’t cheap.Best of luck.
Associated Tlescopes Work Question: Hi all! I’ve got a school report in which I have to explain how telescopes work. I have chosen to base my report on reflector telescopes. I need to pinpoint some of the fundamental problems confronting optical systems design… Namely: -spherical aberration and its elimination in reflector telescopes (what is it?) -chromatic aberration and its elimination in lens systems -diffraction effects and their dependence on aperture and wavelength If anyone can give me any information on these areas I’d be eternally grateful.

• Anwser:Try this link: http://dir.yahoo.com/Reference/Encyclopedia/ This will connect you to several on-line encyclopediae. Pick one (I like Britannica.com for general non-technical information like this) and use it’s local search feature to fetch information on your chosen topic. Simply type “reflecting telescope” or “spherical aberration” or whatever into the box and let the web engine do the work. Don’t forget to credit your sources in your report. The more you pay for eternal gratitude, the longer it lasts.

Associated Tlescopes Work Question:live with you making unsubstantiated claims about nature, because those are actually a challenge to disprove sometimes. What the hell is the point in telling everyone a telescope works differently from how it really works? Telescopes were invented by humans. It’s not like there’s anything mysterious about them. Nothing about how they work is really in question. As many have before, I implore you to look this up.

• Anwser:Telescopes work with a deeper scientific reasoning than was shown to man at this present time. At the level I analyzed goes into the relativistic considerations, at the sub-sub- atomic level using the Smart Model Atom theories…. . Note the Sub-atomic level is conventionally analyzed, I went to the SUB-SUB- atomic level, beyond all modern day scientist…. .
