The Observatory welcomes pre-scheduled small groups to visit our facilities on public viewing nights. We ask that all groups larger than 10 arrange their visits to the observatory so that we can manage the number of visitors to our program. Families and smaller groups are welcome at all times and do not need to make prior arrangements.
