Can I print star charts showing the
whole sky?
Yes, in Starry Night Pro and Pro Plus.
Choose Preferences from the File menu
(Windows) or the
Starry Night menu (Macintosh), choose
General from the dropbox in the upper
left corner of the Preferences dialog box,
and check the box marked “Allow
Maximum Zoom Out”. Then continue
zooming out using the left zoom button
until you have a circular field of view of
180°, which is the entire hemisphere of
sky that is above the horizon at any one
time. Then choose File->Print to print this
image.
Why do the movies I made with Starry
Night have distorted colours when I
play them back?
This is a result of the compression method
which you used when saving the movie.
From within Starry Night Pro and Pro
Plus, choose
Preferences from the File menu
(Windows) or the Starry Night menu
(Macintosh) and then choose QuickTime
from the dropbox in the upper left corner
of the Preferences dialog box, and click
the QuickTime Movie Preferences
button. The "Compression Settings"
window which opens allows you to
modify the compression settings. The top
dropbox in this window is the compression
method. If you saw distorted colors in the
movies you made, try changing the
compression method. "Sorenson Video 3"
is a good compressor which usually
doesn't distort the original images
noticeably. Also make sure that the
"Quality" slider in the "Compression
Settings" window is all the way to the
right.
Telescopes
What telescopes can I control with
Starry Night?
In Starry Night Pro or Pro Plus, choose
Configure from the Tel e sco pe pane to see
a pull-down list of currently supported
telescopes. The list of telescopes that can
be controlled with Starry Night is
constantly changing, and new telescope
models are added on a regular basis.
Constellations & The Zodiac
How do I follow the Sun's path through
the Zodiac over the course of a year?
Set the time to a time of day where the Sun
will be above the horizon all year, for
example 12 Noon. Select View->Hide
Daylight to turn off sunlight, so that you
can see the background stars. Turn on the
Zodiac constellations by choosing the
Zodiac stick figures from the Constellation
Options dialog box in the Constellations
layer of the Options pane. Change the
time step in the toolbar to a discrete step of
1 day and press the Forward button in the
time mode controls to run time forward
and watch the Sun move through the
Zodiac.
The Sun appears to be in the wrong
Zodiac constellation on a given date.
Astrology uses the constellation
boundaries as they existed several
thousand years ago. Since that time, the
