Objects through the telescope don look like the pictures in my science book. Why do some things look fuzzy, even in a telescope?
The pictures in your science book are time-exposure photographs. The eye of a camera is very different from the eye of a human. A camera’s shutter can be opened for several minutes, or even hours, during which time a copious amount of light can be collected from even a dim source, to produce a highly detailed image. Our eyes just don’t work that way, so some things will look fuzzy in even the largest telescopes.
