Optical observation
WebOptical telescopes require at minimum two lenses, the objective and the eyepiece. The simplest kind of telescope is called a refractor. In a refracting telescope, the light is collected through the objective lens and then enlarged with the eyepiece, which basically acts as magnifying glass that enlarges the image produced by the objective lens ...
