Take a Picture Itll Last Longer

While Andromeda may be seen with a modest amateur telescope as a fuzzy patch of light, photographic equipment or an electronic CCD camera is required to make out the kind of detail in a galaxy that we are used to seeing in astronomy magazine pictures. In order to see sweeping arms and dark bands of dust in other galaxies, we need to collect more light, either by using a larger aperture (a big telescope), or waiting longer (taking a sufficiently exposed conventional or electronic photograph).
