* The '''main power switch''' for the telescope and lighting circuits is just inside the second front door on the right. Switch this on when you enter. A red light will illuminate above the switch.
* '''Foyer and stairwell light switches''' can be found on the same right-hand wall, just around the corner to the right, at the foot of the stairs. There is a second switch for the stairwell/foyer lights at the top of the stairs.
