the colors is discussed below.)

   Most of the items generate a list of events during a particular
time span. For these,  you set Guide's date and time to the start of
the time span,  click on the menu option, and tell Guide for how long
a span you want data.

   Suppose you want lunar rise/set and libration data for October
1997. You would enter the Time Dialog and set the date and time to 1 Oct
1997. Now enter the Tables Menu, select the top option, and tell Guide
you want data for 31 days. A window will come up with data for that
time span. The window includes "Save to File" and "Print" options.
                                                            
   The "Jupiter events" option will make a list of Jupiter's satellite
events,  the occultations,  shadows,  eclipses, and transits that are
visible with small telescopes.  It is the sort of list Guide shows in
"More Info" for Jupiter (page 15), but you can set the time span
instead of settling for a fixed seven days.

   The "GRS transits" option will make lists of times when the Great Red
Spot transits (is best placed for viewing).  (If you just want to find
out when it will next transit,  just right-click on Jupiter and ask
for "More Info".)                                      
                                                       
   The "Current asteroids" and "current comets" options are extensions
of the data shown in Quick Info.  Quick Info always shows currently
visible asteroids down to magnitude 11,  and comets to mag 15. In the
Tables Menu,  you can set a different limiting magnitude and get a
little more control over how much data you receive.
                                                    
   "List Planet Features" will result in a list of all features on
whichever planet(s) are currently in the field of view,  and which are
also large enough to show disks at the current zoom level.  (In these
respects,  the list will resemble that seen for the "Go to Planet
Feature" option;  see page 7.)
                                                           
   "List Satellite passes" can be used to get a table of visible
passes for a given satellite,  or a table for many or all satellites.
It brings up a dialog box in which you can specify a satellite name.
Enter,  for example,  "ISS",  and passes of the International Space
Station would be found.  Enter "*",  and it is interpreted as a
"wild card";  passes of _all_ satellites will be tabulated.  Between
these extremes,  you could enter "Landsat*" to get passes of all the
Landsat-related satellites.

   You then can specify the number of days to be covered (starting
from the currently-set time in Guide);  and there's a check-box to
tell Guide to show only "visible" passes,  that is,  ones in which
the satellite gets brighter than a certain magnitude,  gets higher
than a certain altitude above the horizon,  and does so with the
sun at least a certain altitude below the horizon.  You can set
those "certain amounts" in the dialog box.  (Or,  if you turn off
