A telescope is a device that permits us to bring distant objects nearer to us so we can study them. A nice example is the numerous planets, universes, and stars in outer space. Some go from $1 at the toy store to the $1.2 bln Hubble Telescope. There are 2 sorts of telescopes. Refractors employ a glass lens. Reflectors use mirrors rather than a lens. We'll take the different pieces of a microscope and see how they work. The target lens in a Refractor or first mirror in Reflectors gather inward-bound light and brings it to a focus. The eyepiece takes that very same light and magnifies it to take up a huge part of the retina of the eye. Thus, it requires a small image and spreads it out to make it seem bigger. There are 2 general elements to any telescope.

One is how well it can collect light. The other one's the magnification of the image you are viewing. Picking up light is related right to the diameter of the lens. The more light picked up, the brighter the image. Magnification is the facility to take an object as a far distance and enlarge it so you can see it obviously. Any magnification can be had by employing different eyepieces depending on the object you are endeavoring to view. Here's a simplified reason. Get two magnifying glasses and a chunk of paper. Hold one of the glasses between you and the paper. At that point, the image will be hazy and meaningless. Take the second glass and place between your eyes and the 1st glass. Moving the 2nd glass down or up should bring the bit of paper into view. It's going to be bigger and upside down though.
