Fast Steering Mirrors Make It Possible For Telescopes To Get The Best Results Possible

All telescopes, whether they are the one that you use in your backyard to the Hubble telescope, have one thing in common: they depend on mirrors to make sure that they work. When it's a small telescope, like the one that you would use at home, then it isn't as important that the mirror be set in such way that there is very little to no distortion or error, but when you get to the large, professional, or research telescopes, the mirrors must be perfect; they must not add any jiggle, and they must not add in any noticeable distortion.
