Rats. I can't find my copy. I think the trick is that it needs to drive it at sidereal time so it's off a bit from 60 Hz. I forget what they start with. What do serious (optical) telescopes use for a time base? What did Hubble use? What did they use for the Palomar Sky Survey? -- These are my opinions, not necessarily my employer's.
