We present the Survey for Transiting Extrasolar Planets in Stellar Systems (STEPSS). Our goal is to assess the frequency of close-in extrasolar planets around main-sequence stars in several open clusters. By concentrating on main-sequence stars in clusters of known age, metallicity, and stellar density, we will gain insight into how these various properties affect planet formation, migration, and survival. Our primary instrumentation is the MDM 8Kx8K Mosaic CCD imager, which in combination with the MDM 2.4m telescope yields a 25x25 square arcmin field of view. We present first results from our 19 night photometric campaign on the old, solar metallicity cluster NGC 1245, and our 30 night campaign on the rich, 500 Myr-old cluster NGC 2099.
