Time scale (fixed):
The Star disc tray needs to be open. Time from 20:00
(8 p.m.) to 02:00 (2 a.m.) is shown. Align the date dial with
the time scale to project stars at a particular time. Each
subdivision equals 30 minutes.
Date dial (adjustable):

Adjust the dial to project the stars
you want to see from a particular
date. Each subdivision equals 2
days. The long mark corresponds
to the last day of the previous
month.
