REM (Rapid Eye Mount) is a 60 cm diameter fast reacting telescope located in the La Silla premises of the ESO Chilean Observatory (29°15′S and 70°44′W).
The telescope hosts two instruments: REMIR, an infrared imaging camera, and ROS2, a visibile imager with 4 simultaneous passbands. The two cameras can also observe simultaneously thanks to a dichroic placed before telescope focus the same field of view of 10x10 arcmin. Thus, 5 images are obtained at the same time: g,r,i,z,IR.
The Observatory is operated for INAF by the REM Team, a delocalized group of people.
