We propose to use the HST PC in snapshot mode with the broad F785LP filter to obtain high resolution images of the inner regions of a sample of 102 Markarian (Seyferts and starburst) galaxies. In the chosen redshift range, these images will have a resolution of 15 to 60 pc and will cover the inner 500 to 800 pc near the nucleus. The F785LP band-pass will image the stellar continuum in a region with little internal absorption and will be free of atmospheric OH emission. We will use these images to analyze the morphology and to measure the stellar nuclear luminosity function for this matched sample of active galaxies. Comparing these with similar data for "normal" galaxies from the HST archives will allow us to search for any features which differentiate the host galaxies Seyferts from those of normal galaxies and may help identify the large-scale mechanisms responsible for replenishing the material which gives rise to the Seyfert phenomenn. These observations will also help answer the question of whether differences exist between the hosts of Seyfert 1 and Seyfert 2 galaxies.
