Out of interest, do cars travelling along Burrendong Rd give you any issues..?

Fingers crossed.

Cars don't seem to be a problem. The observatory is about 400 metres back from the road, and 30 metres vertically above it. Traffic is extremely light overnight - you could have a game of chess in the middle of the road. The road also goes through a deep cutting at the closest point. The two big freight trains that go through overnight have blisteringly bright headlights but they're very directional.

Then there is the occasional 'roo shooter a couple kilometers away. Their search lights can briefly light up the observatory dome. But we've never seen any evidence of a bad sub due to their infrequent activities, and so far we've never been shot, either.
