Summary
Spectroscopic observation of stars and galaxies are intrinsically limited in number by current instrumentation at telescopes. In the last years, a strong science interest has developed to increase significantly the number of spectra of stars and galaxies to conduct statistical analysis. A number of international projects are thus in development. The table below give a summary of current facilities (SDSS and AAT) and the new instruments in development (PFS, DESI, 4MOST, MOONS, WEAVE and MSE).
| Project | Telescope Diameter | Number of fibers |
|---|---|---|
| SDSS | 2.5m | 1000 |
| AAT – AAOmega | 3.9m | 400 |
| Subaru – PFS | 8.2m | 2400 |
| Mayall – DESI | 4.0m | 5000 |
| VISTA – 4MOST | 3.7m | 2400 |
| VLT – MOONS | 8.2m | 1000 |
| WHT – WEAVE | 4.2m | 1000 |
| CFHT – MSE | 10m | 3200 |
