Reflecting Telescope - Refraction Telescope The objective lens is replaced by a concave parabolic mirror of large aperture. The images in such telescopes are brighter and have a high resolving power compared to astronomical telescope..

An instrument used for observing distinct images of heavenly bodies. Astronomical Telescope In the normal adjustment, the final image is formed at infinity. The magnifying power under situation is as follows. O = objective E = Eyepiece O 1 F 0 = Focal length of ob..

The rays of light coming from a distant object (PQ) form a parallel beam of light. This parallel beam of light is focused by the objective in a plane passing through its focus and perpendicular to the axis and forms the image (P l Q l ). This plane is known as focal plane. The eyepiece is adjusted..

Magnifying power of an astronomical telescope may be defined as the ratio of the angle subtended at the eye by the image to the angle subtended at the eye by the objec..
