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 d'REM Team, a delocalized group of people.

21 Aug 2023 ◊ We are pleased to announce that the 2024A call for observing time at optical/IR telescopes supported by the OPTICON-Radionet Pilot project (ORP) is now open.
See HERE for general information and this page for the details of this call. The deadline is 10th September 2023 23:59 UT. For the submission form please follow the Proposal link.
21 Aug 2023 ◊ Programmed maintenance terminated, PI programmes will be resumed. Please contact for OB scheduling. Unfortunately the infrared camera filter wheel is at the moment still fixed on the H filter. We continue working on this issue.
13 Jul 2023 ◊ Programmed maintenance will stop REM observations from July 30 to August 15. Sorry for the inconvenience.
