The current status of the adaptive optics system for the National Solar Observatory (NSO) 75-cm aperture, evacuated solar telescope at Sunspot, New Mexico, is described. This system is interfaced to a birefringent filter and two solar spectrographs. The optical system provides for the High Altitude Observatory Advanced Stokes Polarimeter (ASP) that measures solar vector magnetic fields. Recently the optical design has been modified to accommodate a 19-segment adaptive mirror and its 19-segment quad-cell tracker.
