Abstract
Some physical parameters of a neutral component of the coma of comet 103P/Hartley have been obtained by the models of Haser and Shul’man. To compensate a quick proper motion of comets in photometric observations, two techniques are investigated: image recovering with algorithms of the inverse problem solution and the method of effective diaphragms. It has been shown that the method of effective diaphragms is preferable.
