How does a reflecting telescope gather light

WebThe light-gathering power of a telescope is directly proportional to the area of the objective lens. The larger the lens, the more light the telescope can gather. Doubling the diameter of the lens increases the light gathering power by a factor of 4. Brightness of images also depends on how big an area the image light is spread over. WebThe resolving power is proportional to the wavelength dividedby the telescope's diameter. For optical wavelengths, the resolving powerin arc seconds is. a = 2.5 x 10^5 x …
