Paper Abstract

Images and spectra obtained with the Hubble Space Telescope (HST) in its current configuration suffer from severe spherical aberration and are therefore routinely restored for visualization and scientific evaluation. Among the non-linear, iterative restoration methods investigated so far, the Richardson-Lucy (RL) algorithm stands out for the quality of the restorations it delivers at modest computational cost. In this contribution we summarize our experience so far with restoration methodology applied to HST imagery and make a first attempt at drawing some general conclusions about its usefulness.
