Please note that if a talk has filled and while the talk is going on, you do not need a reservation to still tour the
Observatory, talk with SAS members in the dome, and look through telescopes if clear. On crowded nights, reservations are needed for
going up to the dome after the talk has finished. Individuals with reservations for the talk automatically get a group number for
going up to the dome, distributed in the order the reservations were made.
