The DAS hosts open houses at Chamberlin Observatory, usually once per month, generally on the Saturday nearest to the first quarter moon. See The Open Houses page for a complete schedule for this year as well as fee information. No reservations are required, but if you have a large group with special needs, please register HERE and provide information on your requirements.
