Keck AO allows observers to obtain near-diffraction limited images in the near IR and diffration limited at
wavelengths longward of 2.0 microns (K band). With NGS-AO and R-band seeing
better than 1 arcsecond, users can expect on-axis Strehl
ratios of 50% or better on guide stars with R-band brighter than
12th magnitude. NGS-AO guide stars must be less than 30
arcseconds from the field of interest. NGS-AO outperforms
LGS-AO down to guide stars with R = 14th magnitude. LGS-AO
guide stars can be as dim as R = 18th magnitude and be 60
arcseconds from the field of interest.
