How is a refracting telescope used for?

In: Astronomy, Physics, Telescopes [Edit categories]

Answer:

The basic task of a reflecting telescope is the same as that of a refracting telescope:

To use the 'gain' of a large collector to amplify the light received from a point source, in order to make dim objects brighter for observation, photography or spectroscopy, or to compensate for the loss of brightness due to magnification of an image.
