HOW TO USE YOUR NEW TELESCOPE
Astronomical telescopes are designed such that the image you see will appear
UPSIDE DOWN and REVERSED, this is acceptable for viewing celestial bodies. However,
this special telescope offers an Erect Image Eyepiece which will deliver a 30x view that will
NOT BE UPSIDE DOWN or REVERSED. This 30x eyepiece is recommended for viewing
either land or night sky based objects.
Using your Eyepieces:
1. You should always start viewing with the lowest power eyepiece, which in this case is the 30x lens. This
30x erect image eyepiece is unique and will correct images to appear right side up as you view them through
the telescope. This is especially beneficial when viewing objects on land. Note: While images will not be
upside down, they may appear tilted slightly. This apparent tilt is due to your viewing position with relation
to the telescope. Depending on where you place your eye, the image tilt will vary. The important feature of
this eyepiece is that the image is right side up and correct left to right (not a mirror image). This eyepiece is
recommended for either land or sky viewing.
2. The 4mm lens is a traditional telescope eyepiece and will provide an image that on land will very clearly
deliver an image that is upside down. However, this is normal and becomes unimportant as you view objects
in the night sky. This eyepiece is recommended for sky viewing only.
Focusing Telescope:
1. After selecting the desired Eyepiece (3), aim Main Telescope Tube (14) at a land-based target at least
200 yards away (e.g. A telephone pole or building). Fully extend focusing tube by turning Rack and Pinion
Focusing Mechanism (2).
2. While looking through selected Eyepiece (3) (in this case the 30x), slowly retract focusing tube by turning
Rack and Pinion Focusing Mechanism (2) until object comes into focus.
Aligning and Using Red Dot Finderscope:
1. Remove plastic insert on bottom side of finderscope to allow battery to make connection with battery
contact for power. Turn power switch on.
2. Look through main telescope tube at low power and establish a well-defined stationary target. Looking
through red dot finderscope, alternate tightening each adjustment wheel (at rear and side of finderscope) until
the red dot of finderscope is precisely aligned and centered on the same object being viewed in main telescope
tube.

Enjoying Your New Telescope
1. First determine your targeted object. Any bright object in the night sky is a good starting point. One of the favorite starting
points in astronomy is the moon. This is an object sure to please any budding astronomer or experienced veteran. When
you have developed proficiency at this level, other objects become good targets. Saturn, Mars, Jupiter, and Venus are good
second steps to take.
2. The first thing you need to do after assembling the telescope as planned is center the desired object in the finderscope.
Provided you did a reasonable job aligning the finderscope, a quick look through the main telescope tube at low power
should reveal the same image. With the lowest power eyepiece (the one with the largest number printed on it) you should
be able to focus the same image that you saw through the finderscope. Avoid the temptation to move directly to the high-
est power. The low power eyepiece will give you a wider field of view, and brighter image--thus making it very easy to find
your target object. At this point with a focused image in both scopes, you’ve passed the first obstacle. If you don’t see an
image after attempting to focus it in, you might consider aligning your finderscope again. Once you pass this step, you’ll will
enjoy the time spent ensuring a good alignment. Every object you center in the finderscope will be easily found in the main
telescope tube, which is important for continuing your exploration of the night sky.
3. The low power eyepieces are perfect for viewing the full moon, planets, star clusters, nebulae, and even constellations.
These should build your foundation. However, for more detail, try bumping up in magnification to higher power eyepieces
on some of these objects. During calm and crisp nights, the light/dark separation line on the moon (called the “Terminator”)
is marvelous at high power. You can see mountains, ridges and craters jump out at you due to the highlights. Similarly,
you can move up to higher magnifications on the planets and nebulae. Star clusters and stars are best viewed through the
low power no matter what.
4. The recurring astronomical theater we call the night sky is an ever-changing billboard. In other words, not the same
movie plays all the time. Rather, the positions of the stars change not only hourly as they seem to rise and set, but also
throughout the year. As the earth orbits the sun our perspective on the stars changes on a yearly cycle about that orbit. The
reason the sky seems to move daily just as the sun and the moon “move” across our sky, is that the earth is rotating about
its axis. As a result you may notice that after a few minutes or a few seconds depending on what power you are viewing
at, the objects in your telescope will move. At higher magnifications especially, you will notice that the moon or Jupiter will
“race” right out of the field of view. To compensate, just move the fine adjustment controls on your telescope to “track” it in
the necessary path.
Helpful Hints
1. Your telescope is a very sensitive instrument. For best results and fewer vibrations set your telescope up on a level loca-
tion on the ground rather than your concrete driveway or your wooden deck. This will provide a more stable foundation for
viewing, especially if you’ve drawn a crowd with your new telescope.
2. If possible view from a location that has relatively few lights. This will allow you to see much fainter objects. You’d be
surprised how much more you’ll see from your local lake or park when compared to a backyard in the city.
3. Using your telescope out a window is NEVER recommended.
4. View objects that are high in the sky if possible. Waiting until the object rises well above the horizon will provide a
brighter and crisper image. Objects on the horizon are viewed through several layers of earth’s atmosphere. Ever wonder
why the moon appears orange as it sets on the horizon. It’s because you are looking through a considerable more amount
of atmosphere than you would directly overhead. (Note: If objects high in the sky are distorted or wavy, you are probably
viewing on a very humid night.) During nights of unstable atmosphere, viewing through a telescope can be frustrating if not
impossible. Astronomers refer to crisp, clear nights as nights of “good seeing.”

Where do I start?
Your telescope can bring the wonders of the universe to your eye. While this manual is intended to assist
you in the set-up and basic use of this instrument, it does not cover everything you might like to know about
astronomy. The first thing you need to do is get a very simple star chart and a flashlight with a red bulb or
red cellophane over the end. For objects other than stars and constellations, a basic guide to astronomy is a
be current events in the sky for suggested viewing. But, some of the standbys that you can see are:
The Moon--a wonderful view of our lunar neighbor can be enjoyed with any magnification. Try viewing
at different phases of the moon. Lunar highlands, lunar maria (lowlands called “seas” for their dark color-
ation), craters, ridges and mountains will astound you.
Saturn--even at the lowest power you should be able to see Saturn’s rings and moons. This is one of the
most satisfying objects in the sky to see simply because it looks like it does in pictures. Imagine seeing
what you’ve seen in textbooks or NASA images from your backyard!
Jupiter--the largest planet in our solar system is spectacular. Most noted features are its dark stripes or
bands both above and below its equator. These are the north and south equatorial belts. Also interesting
are Jupiter’s four major moons. Pay close attention to their positions from night to night. They appear to
be lined up on either side of Jupiter.
Mars--The Great Red Planet appears as a reddish-orange disk. Look at different times of the year and try
to catch a glimpse of the white polar ice caps.
Venus--just like the moon, Venus changed phases from month to month. Some views of brilliant Venus
appear as if you were looking at a distant crescent moon.
Nebulae--The Great Orion Nebula is a very well known night sky object. This and many others are brought
to you by this telescope.
Star Clusters--View millions of stars densely packed in a cluster that resembles a ball.
Galaxies--One of the greatest and most interesting galaxies is our neighbor the Andromeda Galaxy. Enjoy
this and many others.
Much, much, more!

ANSWERS TO COMMONLY ASKED QUESTIONS
1.
The image I see in the telescope appears tilted •
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.
when using the 30x Erect Image Eyepiece
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)

5.
Where do I find the Telescope Focal Length
What can I see with my telescope ?
•
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.
•
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.
What do the numbers on the eyepiece mean ?
•
The numbers on the eyepiece represents the
“focal Length” of the eyepiece.
