Open houses for the general public are offered monthly, frequently timed near the first-quarter moon. These are clear-weather only events, so we are closed if there is any precipitation, strong winds, or mostly cloudy conditions. Note that with the exception of Homecoming and ReUnion weekends, all open houses are free and open to the public with no tickets or reservations required. Only for Homecoming and ReUnion open houses do we issue tickets at the Reamer Campus Center, and these tickets are free. The observatory hotline (518)-388-7100 announces the date and time of open houses as well as announces last-minute cancellations. These cancellations are often decided only 1/2 hour prior to the opening time, unless rain or fully-cloudy conditions make it obvious we cannot open.
