SINCE FOR a TELESCOPE To become a telescope within a tube he has been more complicated of the necessary thing. The telescopes with a tube that slides within another one it is useful, but difficult to construct. This is a very simple version, everything what necsitas it is a pair of magnifying glasses.

The Necsitamos LENSES two lenses to construct a telescope, to greatest are called “objective to him? and to the small “eyeglass?

The objective lens always must be a convex lens. These lenses are heavier to means and they are possible to be used as magnifying glasses. It tries to find one that are great and a little flat. The more flat he is, the more powerful will be your telescope, the more heavy is in center the more weak will be your telescope.

The ocular lens can be convex or concave. If you use a convex lens the telescope will cause that the images are stopped of head. If you use a concave lens, your telescope will not cause that the images are seen of head. This type of telescope is called “Galilean? For your eyeglass tries to find or lens that is small and powerful. The small magnifying glasses can be good for this.

USING the TELESCOPE paunta to a distant object, such as trees. You maintain the ocular lens (small) near your eye and observes through this one. You maintain the objective lens (great) in front of the ocular lens. It moves the great lens slowly forwards, hastq that the image is seen clearly, is a little difficult to find the suitable distance. Your lenses are now a telescope! You can use two lenses of magnifying glass, a great magnifying glass and another small one, nevertheless you will notice that the images have I pull ahead around of colors. This is due to that the great magnifying glass (the objective) works as a prism. This effect is called “chromatic aberration?.
