ASAS-3 is the next step in the All Sky Automated Survey. This paper describes the new hardware, consisting of two wide field (9 × 9 deg) telephoto instruments and one F = 750 mm D = 250 mm telescope with 2 × 2 deg FOV, each equipped with a 2K × 2K CCD camera. Wide field instruments are now observing the whole southern sky (almost 30,000 sq. deg) at the average rate of 0.5 measurements per day. A narrow field instrument is connected to the GCN network and is ready to respond to the GRB alerts in tens of seconds. Preliminary photometric data are presented here and briefly discussed.
