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 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.
TROUBLESHOOTING GUIDE
If after you have set-up your new telescope you are unable to see any 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 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
