Greenwich sidereal times,  comets brighter than magnitude 15,  asteroids
brighter than magnitude 11, the current equation of time,  and the
currently-set date in various calendars (Hebrew,  Islamic,  French  
Revolutionary,  and so forth.)                      
                                                    
   It will also give the limiting visual magnitude for the currently
centered part of the sky for the currently set time, using a method
described by Bradley E. Schaefer in the May 1998 issue of Sky &
Telescope.

7:  DISPLAY MENU                              

   The Display Menu controls what is shown by Guide and how it is
displayed. This menu shows the following items:

Star Display
Data Shown
Legend
CCD Frame
Inversion Menu
Ticks,  Grids,  Etc.
Screen font
Printer font
Direct to screen
Background
Isophotes

   The Star Display option (page 17) brings up a dialog box
with controls over how stars are labelled,  their sizes, and whether
they are colored by spectral type.

   The Data Shown option (page 19) brings up a dialog box showing
the main types of celestial objects shown by Guide (variable stars,
galaxies, etc.) and providing control over how they are shown
and labelled.

   The Legend option (page 24) is checked when the legend is turned on.

   The CCD Frame option toggles the display of a "camera frame", a
resizable rectangle you can use to indicate the area of sky covered by
a CCD or film camera.  When you turn it ON,  the Frame menu will
appear, which allows you to position,  resize, and tilt the rectangle.
The Frame menu is discussed on page 23.

   The Inversion option brings up a dialog box that lets you reset the
orientation of the chart.  You can use it to make charts that are
flipped north/south,  east/west,  or both. You can also use it to put
the zenith at the top of the charts instead of celestial north,  or
ecliptic north,  or galactic north;  and in addition to that rotation,
you can add an arbitrary amount of rotation to the charts.  The Inversion
option is discussed on page 35.
