Type in the name of your location and
enter your latitude and longitude. You

degrees & minutes, or degrees, minutes
& seconds. Starry Night will convert
your values to degrees and minutes.You
must also enter the correct time zone.
Time zones are calculated according to
the time difference from London,

on Eastern Standard Time are 5 hours
behind London, so you would enter “-5
h” if you are on Eastern Standard Time.

longitude, or time zone, click Lookup

resources that will help you find this
information.

Starry Night For the First Time
After you have entered your home
location, the main screen of Starry Night
appears. This window shows what you
would see if you stepped outside at the
current time, and looked south from your
home location. Direction markers along
the horizon help you orient yourself. If you
open the program at night, you see a star-
filled night sky. If you open the program
during the day, you see a daytime scene
with blue sky and sunshine. A horizon is
shown to give you some perspective.
