Explain working of an astronomical telescope.

The rays coming from a distant object fall on the objective as a parallel beam at some angle say "a" and these rays after refraction and passing through the objective converge at its focus and make an inverted & real image AB. This image acts as an object for the eyepiece. The distance of the eyepiece is so adjusted that the image AB lies within the focal length of the eyepiece. The eyepiece forms the final image. The final image is magnified, virtual, and inverted with respect to the object. The final image is formed at infinity.

What are the uses of an astronomical telescope ?

Astronomical Telescope, a device used to form magnified images of distant objects. The telescope is undoubtedly the most important investigative tool in astronomy. It provides a means of collecting and analyzing radiation from celestial objects, even those in the far reaches of the universe.
