Scientific paper

The central star for some planetary nebulae have not been observed. It is believed that these PN nuclei have temperatures in excess of 100000dK and the large flux in the far ultraviolet produces a nebular surface brightness that overwhelms the stellar radiation in the visual when resolution is seeing limited. The WF/PC spatial resolution will enhance the contrast by the order of 100 while an additional enhancement will be achieved by observing in the UV. This program should result in the detection of these central stars and provide sufficient photometric data to determine the nature of the central star and interstellar extinction.
