"WebJan 22, 2013 · So the light gathered by an 8" scope is a factor of ( 8" aperture area / 6" aperture area ) times a 6" scope. To calculate the area you'd normally use the formula for the area of a circle: pi x radius x radius, or pi x diameter x diameter / 4. So, the aperture area of an 8" aperture scope is pi * 4 * 4, or 16 x pi. " - How does a reflecting telescope gather light
