| الوصف: | We present a design for a wide-field spectroscopic telescope. The only large powered mirror is spherical, the resulting spherical aberration is corrected for each target separately, giving exceptional image quality. The telescope is a transit design, but still allows all-sky coverage. Three simultaneous modes are proposed: (a) natural seeing multi-object spectroscopy with 12m aperture over 3dg FoV with ~25,000 targets; (b) multi-object AO with 12m aperture over 3dg FoV with ~100 AO-corrected Integral Field Units each with 4 arcsec FoV; (c) ground layer AO-corrected integral field spectroscopy with 15m aperture and 13 arcmin FoV. Such a telescope would be uniquely powerful for large-area follow-up of imaging surveys; in each mode, the AOmega and survey speed exceed all existing facilities combined. The expected cost of this design is relatively modest, much closer to $500M than $1000M. Comment: 10 pages. SPIE 13094-191, Ground-based and Airborne Telescopes X, Yokohama 2024 |
