As you enter the warm room there is a lab bench to your left. To your right is the long table with the telescope control computer and the instrumentation computers on it. Ahead of you is the bathroom and a storage room which doubles as a dark room.
In the dome room, you go in the door, turn right and go up a short flight of stairs to the observing platform. A very small window connects the dome room to the warm room, so the telescope operators can monitor the telescope's movements. When observing very faint objects, this window can be blocked to keep the dome room dark.
