background image

object, such as the Moon or a bright star, and 

use the viewfinder’s alignment screws to 

make any necessary refinements.
5. When finished, turn off the red dot 

viewfinder by rotating the on/off switch(20) 

counter-clockwise.

UNDERSTANDING CELESTIAL 

MOVEMENTS AND COORDINATES

Understanding where to locate celestial 

objects and how those objects move across 

the sky is the key to enjoying the hobby 

of astronomy. Most amateur astronomers 

practice “star-hopping” to locate celestial 

objects. They use star charts or astronomical 

software to identify bright stars and star 

patterns as “landmarks” in their search for 

astronomical objects. Another technique 

for locating objects is to use the setting 

circles that are provided on your 

telescope.

UNDERSTANDING HOW CELESTIAL 

OBJECTS MOVE

Due to the Earth’s rotation, celestial bodies 

appear to move from East to West in a curved 

path through the skies.
All stars and celestial objects are mapped 

onto an imaginary sphere surrounding the 

lock knob (7) before rotating the RA axis 

to prevent the counterweight from sliding 

unexpectedly. When the telescope is 

balanced, proceed to aligning the red dot 

viewfinder.

ALIGN THE RED DOT VIEWFINDER

Perform the first part of this procedure 

during the daytime and the last step at night.
1. Point the telescope at an easy-to-find land 

object such as the top of a telephone pole or 

a distant mountain or tower. Look through 

the eyepiece and turn the focuser knob (31) 

until the image is sharply focused. Center 

the object precisely in the eyepiece’s field 

of view.
2. Turn on the red dot viewfinder by turning 

the  on/off switch(20) clockwise.
3. Look through the red dot viewfinder 

(24). Turn one or more of the viewfinder’s 

alignment screws (34) until the red dot 

is precisely over the same object as you 

centered in the eyepiece.
4. Check this alignment at night on a celestial 

Looking at or near the 

Sun

 will cause 

irreversable

 damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
