Results from the Cassegrain adaptive optics system of the Mount Wilson 100-inch telescope

Abstract

Since June of 1994 we have been operating and improving a natural-guide-star adaptive optics system on the Mount Wilson 100-inch telescope.1,3 The system is routinely operated by one person plus a telescope operator. First astronomical observations have achieved image profiles with a full-width-at-half-max (FWHM) of 0.068 arcsec, using a silicon CCD with no wavelength discrimination (Fig. 1).
