IRCLES

Star charts and setting circles will allow you to find the location of 

any known celestial objects viewable by your telescope. By using the 

measurements listed on the mount and the coordinates provided in a 

star chart, you will be able to find stars, planets, nebulae, and galaxies 

for exploration with your telescope. In order to ensure that you can 

use the declination and right ascension coordinate system, you will 

need to first polar align your telescope for your viewing location.

ELESCOPE

Polar alignment of your telescope uses easy to find stars to help you 

find the center of the celestial sphere. Before aligning your telescope, 

you must familiarize yourself with some of the major constellations 

in the night sky. For viewing in the Northern Hemisphere, knowing 

the locations of Polaris (the North Star) and the constellations Ursa 

Major (the Big Dipper) and Cassiopeia (the Queen) will allow you 

to properly align your telescope. In the Southern Hemisphere, you 

will need to use a star chart to find stars near the meridian and the ce-

lestial equator so that you can use the star-drift method to polar align 

your telescope. Both Northern and Southern Hemisphere alignment 

are described here.

Before  you  begin  aligning  your  telescope,  look  at  the  mount  and 

familiarize  yourself  with  the  various  scales  used  in  aligning  your 

scope.  The  topmost  scale  on  the  mount  is  the  declination  scale, 

which shows the declination angle (between 0° and 90° each way) of 

what you are viewing. Slightly below the declination scale is the hour 

circle, which shows the right ascension (from 0 to 24 hours) of what 

you are viewing. The bottommost scale, located just above the base 

of the mount, is the latitude scale which shows latitude measurements 

from 0 to 90 degrees. In order to ensure that your measurements are 

correct when aligning your telescope, it is important to make sure 

that the base of your mount is level. If the base of the mount is not 

level, your measurements will be off and aligning will be much more 

difficult.
