31 4. Application to MOSAIC 32

32 MUSE + AOF

33 NGC 6563 non AO 120 s exposure Airmass 1.3 Dimm 0.9 arcsec measured FWHM (Moffat) A A

34 NGC 6563 with GLAO 120 s exposure Airmass 1.3 Dimm 0.9 arcsec measured FWHM (Moffat) A A

35 deployable mini-ifus for crowded-field multiobject spectroscopy Left: PMAS-IFU 16x16 spaxels (FoV: 8 ) Right: MUSE 300x300 spaxels (FoV: 60 ) Above: Parameters for deployable IFUs of MOSAIC & synergy with MICADO to provide imaging data for precise astrometry

36 Conclusions (1) Crowded field 3D spectroscopy with MUSE + HST works extremely well in globular clusters, even out to distances of nearby galaxies (2) MUSE + HST very efficient in discovering faint continuum and emission line objects (3) Classical sequence of imaging follow-up spectroscopy no longer necessary (4) MUSE target seletion for MOSAIC (5) Crowded field 3D spectroscopy is a powerful tool also for deployable IFUs MOSAIC 37
