The dome show happens no matter what is happening outside. Telescope viewing is different: it needs an actually clear sky, and we would rather cancel a night than point our instrument at clouds and call it an experience.
We post the call by four in the afternoon on the day of a scheduled viewing night, on our phone line and at the front desk. A cancelled night is rescheduled, not refunded silently - we will offer you the next clear date first.
Rain check policy: if a viewing night is called off, your ticket carries over to any future viewing night at no charge, with no expiration. If you would rather have a refund instead, ask at the desk and we will do that too.
