Hi Ray,

Looks as if the LXD75 uses an Autostar controller, and yes, Guide
supports that. Try hooking up your scope to the computer; run Guide,
go into Settings... Scope Control, select the serial port corresponding
to your scope, and tell Guide you have an LX-200. You should be able
to make use of the scope pad to move the scope around.

More generally, all of Meade's go-to scopes use essentially the same
protocol, and Guide can therefore control them all.
