Abstract

This paper compares and discusses the attempts to overcome the "seeing" resolution limit imposed by spherical aberration for the Hubble Space Telescope and by Atmospheric turbulences f the case of ground -based telescopes - From recently reposed experimental data it is shown that wavefront reconstruction algorithms are capable of restoring nearly fully the Hubble’s spherical aberration of the primary mirror. Also from previously reported results of ground-based telescopes which utilize the powerful spectral imaging technique at high and low light levels, we compare for different object magnitudes the two types of telescope resolutions "seeing" resolution, SNR and point source resolution.
