Galaxies will be imaged with the F555W and F814W filters. Serveral objects known to contain ionized gas will also be imaged in narrow-band filters to obtain the gas distribution. In M31 and M32 a special series of ultra-violet exposures will be taken to study the hot stellar population. The sample of objects contains several normal ellipticals covering a broad range in nuclear surface brightness and concentration class, several nearby galaxies covering a range of Hubble types, and a few Seyfert and otherwise slightly abnormal nuclei. The images taken will also be searched for bright stars, inner globular clusters, and absorbing interstellar dust. The far UV exposures in M31 and M32 are designed to discover the source of the the far-UV upturn in the light of old stellar populations. The brightness and luminosity function of any point sources will be measured, along with the brightness and distrubution of the diffuse background light. Fixed_Targets ! Target_Number: 1 !
