1. The image I see in the telescope appears tilted
when using the 30x Erect Image Eyepiece
• This is natural and due to the position of the eye
in relation to the telescope tube. The real benefit of the
eyepiece is to deliver an image that is able to be used
when viewing on land.
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 / 25 = 28X)
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 900mm on most 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 150X and higher.
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 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 Rack & Pinion Focusing Mecha-
nism (3) to bring the object you are trying to view
into focus
