Operating Your Planetarium

1.  Place planetarium on a table in the center of the room. A room 

with smooth, light-colored walls and ceiling works best. A room 
that is roughly square and no larger than 12 x 12 feet provides 
the best projection quality. Star Theater works best when it is 
located two to six feet from the projection surface.

2.  Date selector is located on the light wand. To set your 

planetarium for the beginning of the audio tour, rotate light 

Setting the Date and Time

You can set your planetarium to project the night sky for any date and hour. Here is how:
 1. Setting the date: With projection lamp off, turn light wand until the month you want lines 

up with the pointer on date selector. Below the month, there are markings indicating the 
1st, 10th and 20th of the month. Turn light wand to the left until the date you want lines up 
with the pointer. For example, if you want to project the night sky the way it is on July 4th, 
first select July, then turn further to the left, to just past the mark for the first day of the 
month.

2.  Setting the time: Once you have selected the month and date, rotate the time ring— 

without turning the light wand—so that the time at which the sun sets lines up with the 
pointer. (The time at sunset can be found in the local newspaper or on the Internet.) Now turn the light wand to the exact ti me you 
want. (Note: The months and dates will change on the date selector as you select the time; once you’ve selected the date and set the 
time ring for sunset, the time selection function takes over.) You can set your planetarium to project the stars for any time of the night. 
You can even see what stars are up during the day, when they are not visible.

wand until “AUTUMN” lines up with pointer on the base. (The 

month and date settings and the time ring will be used after 

the audio tour to set your planetarium for a specific date and 

time of day.)

3.  In a darkened room, turn on projection lamp. (Do not look 

directly at the Star Sphere while its light is on, or you will lose 

your darkness adaptation.)
