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  most  astronomical
telescopes.  Since  telescopes  are  used  for
astronomical viewing orientation is not important.  

2.  How do I determine the power my telescope ?

•

  The power of your telescope can be determined

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: 700 

÷

 20 = 35X)

3.  Where do I find the Telescope Focal Length

•

  The telescope focal length is  the  same  focal

length  as  the  objective  focal  length.  For  this

telescope  it  is  700mm.  Telescope  focal  lengths
range  from  600mm  to  1200mm  on  Bausch  &
Lomb® and Bushnell telescopes.

4.  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 any magnification.

5.  What do the numbers on the eyepiece mean ?

•

  The  numbers  on  the  eyepiece  represents  the

“focal length” of the eyepiece.

 
 
 

 

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

•

  Check to see if objective lens cover and all

other lens covers have 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 

Rack & Pinion Focusing Mechanism 

to

bring the object you are trying to view into

focus
