text: Three hundred-times magnification sounds great, but there’s a catch: While high magnification makes an object appear larger, the light gathered by the scope is spread over a larger area, which creates a fainter image in the eyepiece.
text: As the magnification of a telescope increases, each object covers a larger area of the image so the light that was collected for that object is spread over a larger area -- which means the light gets spread thinner -- and the surface brightness of the object drops.
