英文摘要	A relatively unexplored phase space of transients and stellar variability is that of second and sub-second timescales. We describe a new optical observatory operating in the Negev desert in Israel, with a 55 cm aperture, a field of view of 2.degrees 6 x 2.degrees 6 (approximate to 7 deg(2)) equipped with a high frame rate, low read noise, CMOS camera. The system can observe at a frame rate of up to 90 HZ (full frame), while nominally observations are conducted at 10-25 Hz. The data, generated at a rate of over 6 Gbits s(-1) at a frame rate of 25 Hz, are analyzed in real time. The observatory is fully robotic and capable of autonomously collecting data on a few thousand stars in each field each night. We present the system overview, performance metrics, science objectives, and some first results, e.g., the detection of a high rate of glints from geosynchronous satellites, reported in Nir et al. 2020.
