Automatic log spectrum restoration of atmospheric seeing

AbstractThis paper presents an automatic method for (i) digital estimation of the width of the atmospherical seeing in astronomical images of extended objects and (ii) image restoration by using the constrained Jansson-Van Cittert deconvolution algorithm. The estimation of the seeing is achieved by computing the radial profile of the averaged log spectrum of the image. The result of this estimation is then applied to compute the Point Spread Function (PSF) used in the deconvolution process. The method is applied to a photographical image of a sunspot. The quality of the restoration assesses the power and usefulness of the method.
