text: A larger aperture will collect more light and therefore both provide a bigger view and a view which can pick up more detail.
text: The bigger the size, or aperture, of the main optical element, the more light it will collect, and thus the brighter an object will appear.
text: It’s because the smaller sized aperture that can’t collect more light to track dimmer objects.
text: In order to see really fine detail in the optical, you have to move your telescope above the atmosphere: For example, compare these images of Jupiter taken above the Earth's atmosphere (by the 2.4-meter HST), and below the Earth's atmosphere (by the 2.1-meter Nordic Optical Telescope): VERY important: a larger aperture collects more light The real reason astronomers want big telescopes is to detect fainter and fainter objects.
text: Larger apertures collect more light, which means that you can see fainter objects (such as galaxies) or smaller features that are on a solid body (such as craters on the moon).
