4MOST

(4-metre Multi-object Spectroscopic Telescope)
(spectrograph in development for VISTA telescope)

4MOST (for 4-metre Multi-object Spectroscopic Telescope) is an fiber-fed optical multi-object spectrograph on VISTA, having replaced VIRCAM, the telescope's original camera. 4MOST intends to simultaneously obtain spectra for 2400 objects over a 4 square degree field. It was installed in 2024 and commissioning is in progress, with normal operation expected in 2026.
