  We describe the results from a new instrument which combines Lucky Imaging
and Adaptive Optics to give the first routine direct diffraction-limited
imaging in the visible on a 5m telescope. With fast image selection behind the
Palomar AO system we obtained Strehl ratios of 5-20% at 700 nm in a typical
range of seeing conditions, with a median Strehl of approximately 12% when 10%
of the input frames are selected. At wavelengths around 700 nm the system gave
diffraction-limited 35 milliarcsecond FWHMs. At 950 nm the output Strehl ratio
was as high as 36% and at 500 nm the FWHM resolution was as small as 42
milliarcseconds, with a low Strehl ratio but resolution improved by factor of
~20 compared to the prevailing seeing. To obtain wider fields we also used
multiple Lucky-Imaging guide stars in a configuration similar to a ground layer
adaptive optics system. With eight guide stars but very undersampled data we
obtained 300 milliarcsecond resolution across a 30X30 arcsec field of view in
i' band.
