Hi Joe,

Yes, you should use the LX-200 radio button. The command sets are
indeed not entirely identical. But the portions used by Guide are
identical. I have a Meade 70mm ETX AutoStar; it's very convenient
for running quick tests (though it's not all that wonderful for actual
observing; I'd just as soon use 10x50 binox for that... less setup time,
no batteries, etc.) The AutoStar works just fine with Guide.
