Editorial Review

Observatory tours, which last 90 minutes, are given select Mondays at 8:30 p.m. The tour has three parts: a 20-minute video on the history of the observatory, a viewing of the master clock and, weather permitting, a look through the 12-inch telescope.

-- John Kelly and Craig Stoltz

Notes: Disabled access is limited. Tours are not recommended for those in wheelchairs, and note the late starting time.
