Abstract:
Simulations of a distant cluster of galaxies at z
2 are presented
for the HST cameras COSTAR-corrected FOC, WFPC II, the Advanced Camera, and
for an adaptive optics system that may equip a future 8-meter class
telescope.
Except for the FOC and PC II, the faint
objects are detected in 200 minutes, with identifiable morphological
types. The Advanced Camera offers the biggest advantages due to its large
field, great sensitivity, and high angular resolution.
