www.meade.comReflecting Telescopes use a concave primary mirror to collect light and form an image. In the Newtonian type of reflector, light is reflected by a small, flat secondary mirror to the side of the main tube for observation of the image. In the refracting telescope, light is collected by a 2-element objective lens and brought to a focus at F.
