INTRODUCTION
Setting up your telescope involves these
simple steps:
Your telescope is an excellent beginner’s
instrument, and is designed to observe
objects in the sky. It can be your personal
window on the universe.
1
• Assemble your tripod
• Attach the accessory tray
• Attach the red dot viewfinder
• Attach the eyepiece
The telescope is shipped with the following
parts:
• Optical tube
• Aluminum tripod with an accessory tray
• Two 1.25" eyepieces: MA25mm (28X),
MH9mm (78X)
• Attach the counterweight
• Prepare mount
• Attach the optical tube to the mount
• Red dot viewfinder with bracket
• Telescope mount
• Hardware used in the assembly:
Study the the picture on the next page and
become acquainted with the parts of your
telescope. Then proceed to “Assemble
your Tripod.”
The tube has a focal length of 900mm,
and its reflective mirror has a diameter of
114mm. The lens diameter is one of the
most important pieces of information about
the telescope. The size of the primary
mirror determines how much detail you
will be able to see in your telescope. The
focal length information will help later on to
calculate magnification.

In mapping the surface of the Earth, lines
of longitude are drawn between the North
and South Poles and lines of latitude are
drawn in an East-West direction, parallel
to the Earth's equator. Similarly, imaginary
lines have been drawn to form a latitude
and longitude on the celestial sphere.
These lines are known as Right Ascension
and Declination.

version of longitude is measured in units
of hours (hr), minutes (min), and seconds
(sec) on a 24 hour "clock" (similar to how
Earth's time zones ar determined by
longitude lines). The "zero" line was
chosen to pass through the constellation

astronomers practice "star-hopping" to
locate celestial objects. They use star

bright stars and star patterns as
The celestial map also contains two poles
and an equator just like a map of the Earth.
The celestial poles are defined as those two
points where the Earth's North and South
poles, if extended to infinity, would cross the
celestial sphere. Thus, the North Celestial

astronomical objects. Another technique for
locating objects is to use the setting circles
that are provided on your telescope.
UNDERSTANDING HOW CELESTIAL
OBJECTS MOVE
Due to the Earth's rotation, celestial bodies
appear to move from East to West in a
curved path through the skies.
So just as an object's position on the Earth's
surface can be located by its latitude and
longitude, celestial objects may also be
located using Right Ascension and
Declination. For example: You can locate
Los Angeles, California, by its latitude
(+34°) and longitude (118°). Similarly, you
All stars and celestial objects are mapped
onto an imaginary sphere surrounding the
Earth. This mapping system is similar to
the system of latitude and longitude on
Earth surface maps.

Have a good time when you’re observing. You
may not know everything that there is to
know about a telescope or what all the
sights in the universe are, but that’s OK. Just
point and observe at first.
3. Determine the latitude of your observing
location by checking a road map or
atlas. Release the latitude lock (9) and
tilt the telescope mount so that the star
"Polaris" is centered in the telescope's
viewfinder eyepiece, then re-tighten the
latitude lock.
Have Fun!
TOO MUCH POWER?
You will enjoy your telescope even more as
you learn more about it. But don’t be scared
off by difficult terms or complicated
procedures. Don’t panic! Just relax and enjoy
your scope.
Can you ever have too much power? If the type of
power you’re referring to is eyepiece magnification,
yes you can! The most common mistake of the
beginning observer is to “overpower” a telescope by
using high magnifications which the telescope’s
aperture and atmospheric conditions cannot
reasonably support. Keep in mind that a smaller,
but bright and well-resolved image is far superior
to one that is larger, but dim and poorly resolved.
Powers above 400x should be employed only under
the steadiest atmospheric conditions.
4. If the above steps (1-3) were
performed with reasonable accuracy,
your tele-scope is now sufficiently well-
aligned to the North Celestial Pole for
visual observations.
You will begin to grow and learn more about
astronomy the more you observe. Go to the
library and read some books about the stars
and planets. Read about astronomers of old.
Many of them had telescope no bigger than
the one you are using right now. Galileo,

the result of material thrown out of the
crater when it was struck by a colliding
object. The dark areas on the Moon are
called maria and are composed of lava from
the period when the Moon still had volcanic
activity. You can also see mountain ranges
and fault lines on the Moon.
Focus: Look through the eyepiece and
practice focusing on the object you
have chosen.
Pick out an easy object to observe: A
distant mountain, a large tree, a lighthouse
or skyscraper make excellent targets. Point
the optical tube so it lines up with your
object. Objects will appear upside down and
backwards in this model telescope.
Try out the slow-motion flexible cable
control: Practice using the right ascension
control cable (3) and declination control
cable (4) to move the telescope. These can
come in very handy, especially when you
wish to move the telescope in very small
(fine control) steps.
Unlock the lock knobs: To move the
telescope, you will need to unlock the Right
Ascension (22, Fig. 5) and Declination (23,
Fig. 5) lock knobs (just rotate to unlock or
lock; when locking, only tighten to a “firm
feel,” do not overtighten).
Observe the Moon: When you feel
comfortable with the viewfinder, the
eyepieces, the locks and the adjustment
controls, you will be ready to try out the
telescope at night. The Moon is the best
object to observe the first time you go
out at night. Pick a night when the Moon

your observation of lunar features.
Nine planets (maybe more!) travel in a fairly
circular pattern around our Sun. Any system
of planets orbiting one or more stars is
called a solar system. Our Sun, by the way,
is a single, yellow dwarf star. It is average as
far as stars go and is a middle aged star.
Spend several nights observing the Moon.
Some nights, the Moon is so bright that it
makes other objects in the sky difficult to
see. These are nights that are excellent for
lunar observation.
Beyond the planets are clouds of comets, icy
planetoids and other debris left over from
the birth of our sun. Recently astronomers
have found large objects in this area and
they may increase the number of planets in
our solar system.
Observe the Solar System: After observing
the Moon, you are ready to step up to the
next level of observation, the planets.
When Mars is close to the Earth, you can see
some details on Mars, and sometimes even
Mars’ polar caps. But quite often, Mars is
further away and just appears as a red dot
with some dark lines crisscrossing it.
The four planets closest to the Sun are rocky
and are called the inner planets. Mercury,
Venus, Earth and Mars comprise the inner
planets. Venus and Mars can be easily seen
in your telescope.
Jupiter, Saturn, Uranus, Neptune and Pluto
comprise the outer planets. These planets,
except for Pluto, are made mostly of gases
and are sometimes called gas giants. If they
had grown much bigger, they may have
become stars. Pluto is made mostly of ice.
Venus is seen before dawn or after sunset,
because it is close to the Sun. You can
observe Venus going through crescent
phases. But you cannot see any surface
detail on Venus because it has a very thick
atmosphere of gas.
Jupiter is quite interesting to observe. You
can see bands across the face of Jupiter. The
more time you spend observing these bands,
the more details you will be able to see.
Looking at or near the Sun will cause irreversable damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.

astronomer Galileo, who observed them for
the first time. If you’ve never watched the
Galilean moons in your telescope before,
you’re missing a real treat! Each night, the
moons appear in different positions around
the Jovian sky. This is sometimes called the
Galilean dance. On any given night, you
might be able to see the shadow of a moon
on the face of Jupiter, see one moon eclipse
another or even see a moon emerge from
behind Jupiter’s giant disk. Drawing the
positions of the moons each night is an
excellent exercise for novice astronomers.
Saturn is not the only planet that has rings,
but it is the only set of rings that can be
seen with a small telescope. Jupiter’s rings
cannot be seen from Earth at all—the
Voyager spacecraft discovered the ring after
it passed Jupiter and looked back at it. It
turns out, only with the sunlight shining
through them, can the rings be seen. Uranus
and Neptune also have faint rings.
Other stars to look for are multiple stars.
Very often, you can find double (or binary)
stars, stars that are very close together.
These stars orbit each other. What do you
notice about these stars? Are they different
colors? Does one seem brighter than
the other?
Optional color filters help bring out detail
and contrast of the planets. Meade offers a
line of inexpensive color filters.

They will appear as small, fuzzy clouds. Only
very large telescope will reveal spiral or
elliptical details.
Use a compass to make a circle, or trace
around the lid of a jar. Draw what you see in
your eyepiece inside the circle. The best
exercise for drawing is to observe the moons
of Jupiter every night or so. Try to make
Jupiter and the moons approximately the
same size as they look in your eyepiece. You
will see that the moons are in a different
position every night. As you get better at
drawing, try more challenging sights, like a
crater system on the moon or even a nebula.

You will also be able to see some nebulas
with your scope. Nebula means cloud. Most
nebulas are clouds of gas. The two easiest to
see in the Northern Hemisphere are the
Orion nebula during the winter and the
Triffid nebula during the summer. These are
large clouds of gas in which new stars are
being born. Some nebulas are the remains
of stars exploding. These explosions are
called supernovas.

of the field and, without touching the
telescope, watch it drift through the field to

to be further observed.
Viewing through windows: Avoid setting up
the telescope inside a room and observing
through an opened or closed window pane.
Images may appear blurred or distorted due
to temperature differences between inside
astronomical objects.
Optional Accessory Barlow lens: You can
also change magnification by using a Barlow
lens. The Barlow lens doubles the power of
your telescope (See Fig. 10).
Meade offers a complete line of eyepieces
for your telescope. Most astronomers have
four or five low-power and high power
eyepieces to view different objects and to
cope with different viewing conditions.
STAR CHARTS
Vibrations: Avoid touching the eyepiece
while observing through the telescope.
Vibrations resulting from such contact will
cause the image to move. Avoid observing
sites where vibrations cause image
movement (for example, near railroad
tracks). Viewing from the upper floors of a
building may also cause image movement.
Star charts and planispheres are useful for a variety of
reasons. In particular, they are a great aid in planning a
night of celestial viewing.
A wide variety of star charts are available in books, in
magazines, on the internet and on CD Roms. Meade
Objects move in the eyepiece: If you are
observing an astronomical object (the Moon,
a planet, star, etc.) you will notice that the
object will begin to move slowly through the

caused by the rotation of the Earth and
makes an object move through the tele-

Surf the Web and visit your local library:
The internet contains a huge amount of
astronomical information, both for children
and adults. Check out astronomy books from
your library. Look for star charts—these are
available on a monthly basis in Astronomy
and Sky and Telescope magazines.
Many groups also hold regularly scheduled Star Parties
at which you can check out and observe with many
different telescopes and other pieces of astronomical
equipment. Magazines such as Sky and Telescope and

on a star. Use the 25mm eyepiece and point
the telescope at a moderately bright (second
or third magnitude) star, then center the star
image in the telescope's field-of-view. With
the star centered follow the method below:
