There are many types of telescopes you can use. Refracting telescope which receives light directly throughout a series of lenses. Newtonian Reflecting is another which receives light from a primary mirror and reflects it to a secondary mirror which sends the light to the eye piece. Newtonian Reflectors are my favorite.
Reflecting telescopes tend to be more expensive than refracting telescopes due to their larger mirrors and complex design. Reflecting telescopes also require more precise alignment of their optical components, which can add to the cost.
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.
Refractors and reflectors. One should add the largely Russian-developed Cassegrainean combines features of both systems-called also Maksutov after its Russian inventor who was awarded the Staliln Prize for this feat. They are adapted to (Mirror=Lens) telephoto camera lenses, also.
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.
It's difficult to understand the question, but WikiAnswers doesn't do well with multiple choice questions. In general, refracting telescopes are smaller than reflecting telescopes; a refractor has the light going straight through the tube, and structural considerations force limits on its size. In a reflecting telescope, the light path is folded back on itself, and reflecting mirrors reflect more light than thick lenses can pass through. But the largest current reflecting telescope is perhaps 300 inches in diameter, although larger ones are planned. By contrast, the Very Large Array of radio telescopes is ACRES in total size, and there is no theoretical limit in how large "it" could be - because "it" is actually "they". Dozens, potentially hundreds of radio telescopes can add their size together to develop a more sensitive and more precise instrument.

Do a project about the moon and if you have a telescope like I do take your own pictures and add them to it. Or you can do it about the nebula in the cosmos.
so we can add decoration to earth
They add clarity to an explanation, and may make understanding easier.
The resolution of a telescope is the telescope's ability to determine if two points are seen as two points or one smudgy point. Resolution, or resolving power is measured as an angle below which differentiation cannot be made. The resolution of a telescope is a consequence of the wave nature of light. Because waves can add to each other, or cancel each other, in a process called diffraction, the aperature of the telescope must be as large as possible compared to the distance to the objects and the wavelength of the light to give the best performance. An equation which describes the resolution of a telescope is
The shiny thing you see when looking through the telescope on Club Penguin is typically the target or object you are viewing through the telescope. It could be a star, comet, or even a spaceship depending on the game's theme or event. It's meant to spark curiosity and add an element of mystery to the game.
