| Abstract: | With a view to the further development of the short exposure method with a CCD detector, new observations of the planet Mercury were carried out at the Abastumany Astrophysical Observatory, Republic of Georgia, from October 30 to November 8, 2001. Comparison with the previous data, as well as the results of data processing based on newly developed algorithms, points to considerable progress achieved in the technique for observing Mercury. In some cases, under very favorable atmospheric conditions, the resolution attained is close to the diffraction limit of the astronomic instrument used. For the first time, topographic features on Mercury's surface were reliably resolved. Features with linear sizes as small as 120 km are successfully identified in the disk center. |
