polar axis. Rotate the telescope about the polar axis so that the 

Counterweight Shaft (7)

 is parallel to the

ground (horizontal).

  Loosen the 

Counterweight Lock Screw (located on the counterweight)

, and slide the 

Counterweight (6)

along the shaft until the telescope remains stationary without drifting rotationally about the polar axis.

Tighten 

the Counterweight Lock Screw

, locking the 

Counterweight

 into position.

  Now balance the telescope about the 

Declination Axis (3) 

. Loosen the declination lock screw and the

Cradle Lock Screws

 so that the telescope can slide freely inside the 

Cradles

. Slide the telescope up or

down  inside  the  rings  until  the  telescope  remains  stationary  without  drifting  rotationally  about  the

Declination Axis

. Tighten 

Cradle Lock Screws

. The telescope is now balanced.

 

 

ANSWERS TO COMMONLY ASKED QUESTIONS

1.

 

The image I see in the telescope is upside down and

reversed from right to left ?

 

An  upside-down  and  reversed  image  is  a  common

characteristic of all refractor telescopes. Since telescopes are

used for astronomical viewing orientation is not important.

An erecting lens can be purchased separately that will allow

you to see a “natural” image. The image in the finderscope

will also be upside down and reversed.

2.

 

How do I determine the power my telescope ?

 

The power of your telescope can be determine by dividing

the focal length of the objective lens by the focal length of

the  eyepiece.  The  eyepiece  focal  length  is  the  number

printed on the eyepiece.  (For example: 1000 

÷

 25 = 40X)

3.

 

What can I see with my telescope ?

 

Telescopes with power ranging from 25X to 50X can be

used to view Star Clusters  and  Nebulae.  90X  to  120X

telescope can view galaxies. Most planets can be seen at

150X and higher.

4.

 

What do the numbers on the eyepiece mean ?

 

The numbers on the eyepiece represents the “focal Length”

of the eyepiece.

 

 

TROUBLESHOOTING GUIDE

 

If after you have set-up your new telescope you are unable to see an objects, use this Quick Reference

guide to help you to understand the cause of the problem and quickly determine a remedy

1.

 

I’ve completed the set-up yet I cannot see anything

 

Check to see if objective lens cover has been removed.

 

Try to view an object that is 200 or more yards away.

 

If  there  is  more  than  one  eyepiece  included  with  the

telescope, use the lowest power (highest number) eyepiece

to begin viewing.

 

Use the 

focusing mechanism

  (16) to bring the object you

are trying to view into focus
