Gamma-ray bursts (GRBs) are the most luminous events in the Universe. Their gamma-ray emission is often accompanied by the optical emission. Since the duration of this optical emission (the so-called optical afterglow) is much longer than that of the gamma-ray one (hours to more than a day versus at most a few minutes), the optical observations of these events are very promising. In this paper we show the possibilities of observing the optical afterglows with the relatively accessible telescopes equipped with CCD detectors. Such telescopes are able to obtain series of photometric observations, which can be used for the scientific analysis.
