Abstract

Practically all of ground-based astronomy can benefit from improved angular resolution. Whereas specialized techniques exist (e.g., speckle) or are being developed (e.g., optical interferometry), they are often limited in field size and/or by the available signal level. A significant fraction of optical work relies on CCD imagery of fields of several arcmin, and will probably continue to do so for quite some time. Recent advances in telescope technology (the ESO NTT being the foremost example), careful selection of telescope sites, etc., can do a lot to improve the seeing. But once the hardware is firmly in place, and the data are taken, the only way to improve the resolution is by some image deconvolution technique. Possibly the best among them is the Maximum Entropy Method.
