ALIGNING NORTHSTAR FOR THE FIRST TIME (Continued)
NOTE: THE USER WOULD JUST H AVE TO GET THE TELESCOPE POINTED RELAT I V E LY CLOSE TO
N O R TH. THE A L I G N M E N T W I L L BE REFINED AS WE PROGRESS. HOWEVER, IF YOU CAN FIND T H E
BIG DIPPER AND USE THE "POINTER STARS", FOLLOW THE ARROW ON THE ABOVE DIAGRAM TO
THE NORTH STAR. THE NORTH STAR LIVES DIRECTLYABOVE DUE NORT H !
After pointing the telescope NORTH and making sure the tube is still pointed level, pressing the ENTER button
would complete the rough alignment process.
A polite THANK YOU will then be displayed.
After four simple criteria that any consumer should know, the telescope now knows where over 20,000
astronomical objects are in the night sky to a relative precision. With just two more steps, we will zero in on
pinpoint accuracy.
Now the telescope will lead us through a simple two star alignment process. WE DO NOT NEED TO KNOW
WHERE A N Y S TARS ARE. We just simply follow the directions.
Ascrolling message indicates to CENTER STAR 1 THEN PRESS ENTER
Then the display will read:
The user will simply follow the arrows to zero in on this first guide star. Note that this will be the only bright star
in this area of the sky. By following the arrows on the display it will tell us how far away we are from the guide
s t a r. Move the telescope tube with your hands until the display reads:
Note as you move from greater than 10 degrees away from an object to under ten degrees, the display moves
into tenths of degrees with the arrows acting as decimal points (Example below the
object).
After getting the star zeroed in, you need to do as the screen told you—CENTER STAR 1. In other words, the
star might appear in the lower left corner of your telescope’s eyepiece.
By looking through the eyepiece, center the star in the field of view and press ENTER.
The distance the object is from the center is related to how far outside of a city you might be located or how
accurately you aligned with north.
You would then repeat this process for STAR 2 and press ENTER.
After this step is completed, you will see a display that reads:
(Note: The more stars that appear on the second line of the display the better, up to 5)
After the two star alignment is complete, your Northstar now knows with pinpoint accuracy where
all 20,000+ objects are!!
