   Create Star List is used to generate a list of stars,  down to a
specific limiting magnitude,  that cover the area currently shown
on the screen.  To use this option,  first find the area of
interest,  and set the field size to cover it. Select this menu
option and enter a limiting magnitude. (If you enter, say,  20,
you'll get all the stars in the area.)

   Guide will pause to gather data for stars in the area you've
requested that are brighter than the limiting magnitude you entered.
When it is done,  it will show you the list of stars on the screen.
For each star,  the GSC number,  RA,  dec,  and magnitude will be
listed.  If the data comes from the Tycho or Hipparcos catalog,
numbers for that star from several catalogs may be shown:  the HD,
PPM,  Yale, SAO,  and Hipparcos numbers can be listed.  If the data
comes from the GSC,  then you get different data:  an "object type
code" (0 for stars, 3 for "non-stars") and a plate identifier.

   The format of the RA and dec is the currently selected one (see pages
13 and 32),  as is the epoch.  Once the list is generated,
you can save it to an ASCII file or print it much as you would any
other help topic.

   A few warnings about the list are in order.  If a star appears in both
Tycho/Hipparcos and in the GSC, it will have data from both catalogs.
Sometimes,  this is useful (which is why the second line is not removed),
but in most cases,  one will want to pay attention to the Tycho data and
ignore the GSC data.

   If a GSC star appears on more than one plate in the GSC,  it will appear
more than once in the list.  (Multiple appearances are common,  since the
plates overlap quite a bit.)
                                                       
   The "Miscellaneous Tables" option originally just listed a few tables
of interesting,  but not easily categorized,  events.  Clicking on it
now brings up a long list of tables of events,  such as planetary
occultations,  transits of Mercury and Venus,  dates of meteor showers,
and more.

   If text appears red in the table,  it refers to an event that occurs
below your horizon.  If the text is yellow,  the event is less than ten
degrees above the horizon (visible,  but not by much).  If it's in green,
the event is more than ten degrees above the horizon.  You can click on
any such colored text to cause Guide to recenter on the object/event in
question.
