Which Size Of A Telescope Has The Most Light Gathering Power? [Solved]

The light gathering power increases as the square of this diameter. Therefore, a telescope with twice the diameter will have four times the light gathering power. For example, CSUN’s 14 inch telescope would have (14*4)2 = 3136 times more light gathering power than the human eye!
