One man spent his life in the Blue Mountains bush building Australia's largest telescope
entirely by hand, and never told anyone how remarkable it was. Nearly forty years after Ken Beames' death, his last apprentice is the only person alive who knows what he knew.,

Now, as Sydney's new 24-hour airport switches on overhead, he races to pass everything on before the dark sky Ken built his life around, and the living memory of the man himself, both go out.
