Hi Joe,

Local (and Greenwich) sidereal times, and local mean time, are
available in the Time Zone menu, near the bottom of the list.

You _could_ just go into the time dialog, click on the time zone,
and reset it to LST. But I'd not recommend doing this, because that
setting affects almost every date/time shown by Guide. It's better
to have the "secondary time" in the legend set to show LST.

To accomplish this, go into the legend dialog and click on the
"second time" check-box. (If it's already on, shut it off and then
turn it on.)

When the "second time" option is turned on, you get a choice of
what time zone is used for the second time, and you can select LST
or GST. (This is also a convenient way to have, for example, the
time shown in both UT and your local time zone; or to have a second
time that shows the current MJD or Julian Day.
