  We report the first detection of emission line gas within the host galaxies
of high redshift QSOs. This was done using narrow-band imaging at the
redshifted wavelengths of [O III] and H alpha, using the PUEO adaptive optics
camera of the CFHT. The QSOs are all radio-quiet or very compact radio sources.
In all five observed QSOs, which have redshifts 0.9 to 2.4, we find extended
line emission that lies within 0.5" (a few Kpc) of the nucleus. The emission
(redshifted) equivalent widths range from 35 to 300A. Where there is radio
structure, the line emission is aligned with it. We also report on continuum
fluxes and possible companions. Two of the QSOs are very red, and have high
resolved continuum flux.
