| Description: The larger the diameter of a telescope’s primary mirror, the finer the detail the telescope can resolve. These two images of the Andromeda Galaxy, taken through telescopes with different diameters, show this effect. Increasing the exposure time of the smaller diameter telescope (a), will only brighten the image, not improve the resolution Picture Stats: Views: 578 Filesize: 170.42kB Height: 447 Width: 1350 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=15874 |
