Multi-object Optical and Near-IR Spectrograph

MOONS (for Multi-object Optical and Near infrared Spectrograph) is a multi-object spectrograph in development for European Southern Observatory Very Large Telescope (ESO VLT), aiming for a high spectral resolution, capability to simultaneously observe a large number of objects, with a robotic fiber positioner and a wide field of view over which to observe simultaneously. In 2022, first light was planned for 2023.
