u:
Uranometria magnitude limit toggle.
This function causes the limiting
magnitude of the display to
approximately match that of
Uranometria 2000.0.  The magnitude
symbols will be rescaled from 1 to 10
(instead of 6 to 15), and the "o - set
star mag limit" function will be
disabled.
This is a toggle action -- hitting "u"
again returns the display to the normal
limiting magnitude setting.

o:
Specify the magnitude range for stars
to be displayed.  This is a 2-part
popup menu.  The first selects the
dimmest magnitude to display.  After
picked, a second popup appears for
entering the brightest magnitude.
Star magnitudes are stored to the
nearest half-magnitude.  This popup
sets values to the nearest whole
magnitude, which can be adjusted
by .5 mag using the + and - functions
on the main menu.

<CTL>F5:
Prints a hardcopy chart.
Epson LQ (24-pin), Epson FX (9-pin) and
HP LaserJet IIP emulations only are
supported in this version.  If your
9-pin printer supports double density
FX plotter mode, select "FX DBL DENS".
You can print the chart directly, or
save it to a file.  To print a chart
saved to a file, type:
"copy <filename> <printer port>".
(<printer port> is usually "lpt1").

f:
Sets the size of the field in the
vertical dimension. (With the menu
turned on, the field is square. But
when turned off, the field will be
rectangular).
Use the preset popup selections, or
hit the "KEYBOARD ENTRY" box to
enter the field size to the nearest
arc second using keyboard entry.
The largest allowable field is 20.

l:
Locate an object. You will be prompted
to enter the catalog designation of a
non-stellar object. If found in the
database, the object will be centered
in the display.
Embedded blanks are ignored, and the
search is not case-sensitive.

p:
A popup menu allows you to select the
pan overlap in 0.1 increments. This
determines how far the field will
shift when the PAN function is invoked
using the arrow keys.
For example, a value of .2 will give
an overlap of 20%, which means the
field will shift 80% of the field
size in the panned direction.

Invokes the MOOZ function, which is the
opposite of ZOOM. This will cause the
field to expand to whatever size it was
prior to any previous zoom operations.
Up to 10 prior zooms will be stored,
and you can step back through each one
by repeating the MOOZ function.
The "f" function, "Set Field Size,"
will clear the zoom buffer and start
over.

Displays a list of all the eyepieces
which were entered into the system.
When an eyepiece is selected using the
arrow keys, a circle which matches the
field size for that eyepiece will be
drawn, centered on the display.
The "ENTER PARAMETERS" box allows you
to enter the focal length of your
telescope, edit the eyepiece list, and
set the "FILL SCREEN" option (which

A tabular data listing of all the
non-stellar objects within the
current field is written to a file.
This function will not apply any
filtering other than by position.
If you use this in conjunction with
hardcopy plots, you should remove
the menu before generating the list,
so that the fields for the list and
the hardcopy chart will match.

When displaying dense star fields,
fields with a large number of bright
stars, or just a large field (over 2
degrees),  it may be impossible to
resolve close stars. And non-stellar
objects may be hidden by stars. This
function reduces all star symbols to
1 pixel.
This is a toggle action -- hitting "s"
again restores the symbols to their
normal size.

keys will contract the zoom box.
The incremental change in box size is

Lock must be on!).

Cursor ID function. The first two lines
give the coordinates of the cursor. The

If the center of a non-stellar object
is located within 4 pixels of the cursor
center, a description of that object
will be displayed.

Toggles between night vision mode (an

If you are switching from night vision
to full-color mode, you will have to
respond to an "Are you sure?" check.
This is to prevent an accident in the
field which could result in bodily
injury from the people set up next to
you (especially if they are taking
photographs).
