LENSES AND TELESCOPES – PART 1


A telescope's objective lens is a piece of glass that gathers and bends light, making it possible for you to see an image. The objective lens is located on the TELESCOPES: TELESCOPE MAKING BOOKS A REFRACTING TELESCOPE'S PARTS LIST – Objective Lens – Main Mirror Cell (Holder) – Tube – Focusing Unit – Eyepieces The incoming light enters the objective lens at the entrance to the telescope. The objective lens forms an image at the focal length, f o, of the lens inside the telescope.

HowStuffWorks "How Telescopes Work"


A refractive telescope has a relatively large diameter objective lens to collect the light, followed by a smaller secondary lens or eyepiece. There are a couple different Make your first observations with the simple telescope, the one with the eyeglass lens as objective. At the beginning, keep the objective at the maximum aperture. In the refracting telescope (a) light is collected by a 2-element objective lens and brought to a focus at F. By contrast the reflecting telescope (b) uses a concave
