From November 1985 through May 1986 we conducted an extensive series of observations of comet Halley using the Wisconsin 150mm dual etalon Fabry-Perot spectrometer coupled to the 32 inch west auxiliary of the McMath Solar Telescope on Kitt Peak, Arizona. High spectral resolution (0.2 {angstrom}) scans and images were obtained. Spatial images of comet Halley in (OI)6300 {angstrom} emission have been used to deduce the distribution of cometary O({sup 1}D). The 10 kms{sup {minus}1} bandpass of the system allowed the distribution to be measured with little contamination from airglow (OI)6300 and cometary NH{sub 2} lines in the nearby spectrum. The results were modeled to provide photodestruction lifetimes for cometary H{sub 2}O and OH, the predominant parents of O({sup 1}D).
