The resulting image quality is considerably below the design specifications, and causes a loss of sensitivity of approximately 2.5 magnitudes.

This long awaited event marked the begin of a new phase in X-ray astronomy during that an extension of our present database on X-ray sources by an order of magnitude is expected.

HST Image Restoration - Status and Prospectsds, hardly seen before in optical astronomy. The characteristics of the aberrated point-spread function together with the stochastic properties of quantum-limited data have lead to the recognition of statistical algorithms as the methods of choice for HST image restoration.
