- If a telescope is 10 times bigger in diameter it will gather _________ times more light than a smaller telescopeAstronauts observing from a space station need a telescope with a resolving power of 0.6 arc second at a wavelength of 530 nm and a magnifying power of 220. Design a telescope to meet their needs.What will its light-gathering power be, compared with a dark-adapted human eye? (Assume that the pupil of your eye can open to a diameter of about 0.8 cm in dark conditions.)(State the necessary primary diameter of the telescope, in m, and the ratio of the focal lengths below.)Geostationary satellites cannot be seen in a telescope from Albany because they are always directly over the Equator.
