And, that is why ground based telescopes use adaptive optics to compensate for the instabilities in Earth's atmosphere. Using a laser to generate a "pseudo-star" high in the upper atmosphere they can determine what adjustments need to be made to the telescope's optics to null the effects of the atmospheric turbulence. These adjustments happen on the order of 100s to 1000s of times a second allowing Earth based telescopes to gather images rivaling the space based Hubble. Yes.
