The 

PowerSeeker 

 is a classical, two element refracting telescope that comes on an altazimuth mount. This section 

instructs you on the proper assembly and use of your 

PowerSeeker 

 telescope, which is shipped in one box, containing 

all the parts you need to assemble it.  Unpack and lay out all of the parts in a large, clear area where you’ll have room 
to work.  Keeping  track of the parts, use the list below and the telescope diagram to confirm you have, and can identify 
each part. 
 

1.  Objective Lens    
2.  Telescope Mounting Plate 
3.  Altitude locking screw  
4.  Tripod Head  
5.  Tripod legs with a collapsible center leg brace  
6.  Focus Knob  
7.  90° diagonal .96" 
8.  Eyepiece .96"  
9.  Finderscope Bracket  
10.  5x24 Finderscope  
11.  Telescope Optical Tube

To set up the tripod, locate the tripod legs (5) and the telescope optical tube (11). 

 

Remove the tripod  from the box and spread the legs apart until the center leg brace is fully extended.

 

1.  Extend the inner portion of each of the three tripod legs to the desired height.  Tighten the thumb screw on the 

side of each tripod leg to secure them in place. See Figure 1 

2.  After all the screws have been hand-tightened, you are ready to attach the telescope tube to the mount.  

Remove the altitude locking screw (3) from the tripod head (4). 

3.  Place the telescope tube on the altazimuth mount so that the hole in the mounting platform (2) lines up with 

the holes in the tripod head (4).  

4.  Insert the altitude  locking screw (3) through the tripod head (4) and mounting platform (2) and tighten the 

retaining nut to the other side of the screw.

Your telescope comes with the following optical accessories: 

• 

Star Diagonal .96" 

• 

20mm eyepieces .96" 

• 

12mm eyepieces .96" 

• 

4mm eyepiece .96 " 

• 

3x Barlow Lens .96"  

 

1.  Remove the caps from the focuser and the diagonal . 
2.  Insert the chrome end of the diagonal into the focuser (Figure 3) and lock into place by tightening the thumb 

screws on the focuser.  

3.  Remove caps from the eyepiece and place it into the diagonal (Figure 4).  Lock it into place with the thumb 

screw. 

4.  Your telescope also comes with a 3x Barlow lens which triples the magnifying power of each eyepiece (see 

Magnification

 section of the manual).  To use the barlow lens, remove the diagonal and insert the barlow lens 

directly into the focuser. Then start by using the low power  eyepiece such as the 20mm, and insert it either 
directly into the barlow lens or into the diagonal. See Figure 5.
