text: A two-inch telescope, for example, will gather about 16 times more light than a typical eye, and will allow stars to be seen to about 10th magnitude; a ten-inch (25 cm) telescope will gather about 400 times as much light as the typical eye, and will see stars down to roughly 14th magnitude, although these magnitudes are very dependent on the observer and the seeing conditions.
