INTRODUCTION
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.
The telescope is shipped with the following
parts:
• Optical tube
• Aluminum tripod with an accessory tray
• Two 1.25" eyepieces: MA25mm (28X),
MH9mm (78X)
•Red dot viewfinder with bracket
• Telescope mount
•Hardware used in the assembly:
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.
Setting up your telescope involves these
simple steps:
• Assemble your tripod
• Attach the accessory tray
• Attach the red dot viewfinder
• Attach the eyepiece
• Attach the counterweight
• Prepare mount
• Attach the optical tube to the mount
Study the the picture on the next page and
become acquainted with the parts of your
telescope. Then proceed to “Assemble
your Tripod.”

No ot te e: :If the counterweight is
positioned as recommended
previously then the telescope is
already approximately balanced.
1. Loosen the right ascension lock (22).
The telescope mount will turn freely
about the polar axis. Rotate the
telescope about the polar axis so
that the counterweight shaft (6) is
parallel to the ground (horizontal).
2. Loosen the counterweight's locking
thumbscrew (7) and slide the
counterweights (5) along the shaft
until the telescope remains in any
given position without tending to drift
up or down around the polar axis.
Retighten the counterweight lock
(31).The telescope is now balanced.
PREPARE MOUNT
1. Attach the flexible cables (3) and (4).
These cables are secured in place
with a firm tightening of the

ATTACH THE OPTICAL TUBE TO THE MOUNT
1. Lay the optical tube (12) with cradle rings
(14) onto the saddle plate (13).
2. Tighten the cradle ring attachment lock
knob (36) to a firm feel.
ALIGN THE RED DOT VIEWFINDER
Perform the first part of this procedure
during the daytime and the last step at night.
1. Point the telescope at an easy-to-find
land object such as the top of a telephone
pole or a distant mountain or tower. Look
through the eyepiece and turn the focuser
knob (31) until the image is sharply
focused. Center the object precisely in the
eyepiece’s field of view.
2. Look through the red dot viewfinder. Turn
one or more of the viewfinder’s alignment
screws (34, Inset B) until the red dot is
precisely over the same object as you
centered in the eyepiece.
3. Check this alignment at night on a
celestial object, such as the Moon or
a bright star, and use the viewfinder’s
alignment screws to make any
necessary refinements.
UNDERSTANDING CELESTIAL MOVEMENTS
AND COORDINATES
Understanding where to locate celestial
objects and how those objets move across
the sky is the key to enjoying the hobby of
astronomy. Most amateur astronomers
practice "star-hopping" to locate celestial
objects. They use star charts or
astronomical software to identify bright
stars and star patterns as "landmarks" in
their search for astronomical objects.
Another technique for locating objects is to
use the setting circles that are provided on
your telescope.
SUN WARNING!
NEVER USE YOUR TELESCOPE TO LOOK AT
THE SUN!
LOOKING AT OR NEAR THE SUN WILL
CAUSE INSTANT AND IRREVERSIBLE
DAMAGE TO YOUR EYE. EYE DAMAGE IS
OFTEN PAINLESS, SO THERE IS NO
WARNING TO THE OBSERVER THAT
DAMAGE HAS OCCURRED UNTIL IT IS TOO
LATE. DO NOT POINT THE TELESCOPE OR
ITS VIEWFINDER AT OR NEAR THE SUN.
DO NOT LOOK THROUGH THE TELESCOPE
OR ITS VIEWFINDER AS IT IS MOVING.
CHILDREN SHOULD ALWAYS HAVE ADULT
SUPERVISION WHILE OBSERVING.

thumbscrews located at the attachment
ends of each cable.
2. Tilt the polar axis of the telescope to
roughly a 45°angle with the horizon:
Loosen the latitude adjustment lock
(9) so you can move the mount to the
desired position.
3. Re-tighten the latitude adjustment lock to
secure the mount in place.
Meade114EQ_AR 4/13/06 4:08 PM Page 7

Pole crosses the celestial sphere. The North
Star, Polaris, is located very near the North
Celestial Pole.
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
can locate the Ring Nebula (also known as
"M57") by its Right Ascension (18hr) and
its Declination (+33°).
•
•R RI IG GH HT TA AS SC CE EN NS SI IO ON N( (R R. .A A. .) ): :This Celestial
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
Pegasus, a sort of cosmic Greenwich
meridian. R.A. coordinates range from 0hr
0min 0sec to 23hr 59min 59sec. There are
24 primary lines of R.A., located at 15-
degree intervals along the celestial
equator. Objects located further and
further East of the zero R.A. grid line (0hr
0min 0sec) carry higher R.A. coordinates.
•
•D De ec cl li in na at ti io on n( (D De ec c. .) ): :This celestial version
of latitude is measured in degrees, arc-
minutes, and arc-seconds (e.g., 15°27'
33"). Dec. locations North of the celestial
equator are indicated with a plus (+) sign
(e.g., the Dec. of the North celestial pole
is +90°). Any point on the celestial equator
(such as thee constellations of Orion,
Virgo, and Aquarius) is said to have a
Declination of zero, shown as 0°0' 0".
All celestial objects therefore may be
located with their celestial coordinates of
Right Ascension and Declination.
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.
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.
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 R
Ri ig gh ht tA As sc ce en ns si io on n
and D
De ec cl li in na at ti io on n. .
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
Pole is that point in the sky where the North
6
Meade114EQ_AR 4/13/06 4:08 PM Page 8

located in Earth's Southern Hemisphere with
the South Celestial Pole), astronomical
objects may be followed, or "tracked," by
moving the telescope about one axis, the
polar axis.
If the telescope is reasonably well aligned
with the pole very little use of the
telescope's Declination flexible cable control
is necessary. Virtually all of the required
telescope tracking will be in Right
Ascension. For the purposes of casual visual
telescopic observations, lining up the
telescope's polar axis to within a degree or
two of the pole is more than sufficient: with
this level of pointing accuracy, the telescope
can track accurately by slowly turning the
telescope's R.A. flexible cable control and
keep objects in the telescopic field of view
for perhaps 20 to 30 minutes.
POLAR ALIGNMENT OF THE EQUATORIAL
MOUNT
To line up the Meade 114 EQ-AR with the
pole, follow this procedure:
1. Release the Azimuth lock (30)of the
Azimuth base, so that the entire
telescope-with-mounting may be rotated
in a horizontal direction. Rotate the
telescope until it points due North.
Use a compass or locate Polaris,
the North Star, as an accurate
reference to North (See Fig. 7).
2. Level the mount with the horizon,
if necessary, by adjusting the heights of
the three tripod legs.
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.
4. If the above steps (1-3) were
performed with reasonable accuracy,
your telescope is now sufficiently well-
aligned to the North Celestial Pole for
visual observations.

LINING UP WITH THE CELESTIAL POLE
Objects in the sky appear to revolve
around the celestial pole. (Actually,
celestial objects are essentially "fixed"
and their apparent motion is caused by
Earth's rotation). During any 24 hour
period, stars make one complete
revolution about the pole, circling with the
pole at the center. By lining up the
telescope's polar axis with the North
Celestial Pole (or for observers Fig. 7
Meade114EQ_AR 4/13/06 4:08 PM Page 9

Once the mount has been polar-
aligned as described above, the
latitude angle need not be adjusted
again, unless you move to a
different geographical location
(i.e. a different latitude). The only polar
alignment procedure that you need to
perform each time you use the telescope
is to point the polar axis due North, as
described in step 1 above.
THE MOST IMPORTANT RULE
We have one very important rule that
you should always follow when using
your telescope:
Have Fun!
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.
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.
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, who is one of the first astronomers
to use a telescope, discovered four of the
moons of Jupiter with a telescope about the
same size as yours (and his didn’t even focus
very well!).
OBSERVING
Observe during the daytime: Try out your
telescope during the daytime at first. It is
8
TOO MUCH POWER?
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.
easier to learn how it operates and how to
observe when it is light.
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.
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).
Use the red dot viewfinder: If you have not
done so, align the viewfinder (24) with the
telescope’s eyepiece (19) as described
Fig. 8
Meade114EQ_AR 4/13/06 4:08 PM Page 10

earlier. Look through the red dot viewfinder
until you can see the object. It will be easier
to locate an object using the red dot
viewfinder rather than locating with the
eyepiece. Line up the object using the
viewfinders red dot.
Look through the eyepiece: Once you have
the object lined up in the viewfinder, look
through the optical tube’s eyepiece. If you
have aligned your viewfinder, you will you
see the object in your eyepiece.
Focus: Look through the eyepiece and
practice focusing on the object you
have chosen.
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.
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
is a crescent. No shadows are seen
during a full Moon, making it appear flat
and uninteresting.
Look for different features on the Moon. The
most obvious features are craters. In fact
you can see craters within craters. Some
craters have bright lines about them. These
are called rays and are 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.
Use a neutral density filter (often called a
“moon filter”) when observing the Moon.
Neutral density filters are available from
Meade as an optional accessory and
enhance contrast to improve your
observation of lunar features.
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.
Observe the Solar System: After observing
the Moon, you are ready to step up to the
next level of observation, the planets. There
are four planets that you can easily
observe in your telescope: Venus,
Mars, Jupiter and Saturn.
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.
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.
9
Meade114EQ_AR 4/13/06 4:08 PM Page 11

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.
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.
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.
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.
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.
One of the most fascinating sights of Jupiter
are its moons. The four largest moons are
called the Galilean moons, after the
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.
10
Any small telescope can see the four
Galilean moons of Jupiter (Fig. 8), plus a few
others, but how many moons does Jupiter
actually have? No one knows for sure! Nor
are we sure how many Saturn has either. At
last count, Jupiter had over 60 moons, and
held a small lead over Saturn. Most of these
moons are very small and can only be seen
with very large telescopes.
Probably the most memorable sight you will
see in your telescope is Saturn. Although you
may not see many features on the surface of
Saturn, its ring structure will steal your
breath away. You will probably be able to see
a black opening in the rings, known as the
Cassini band.
Fig. 9
Meade114EQ_AR 4/13/06 4:08 PM Page 12

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.
Optional color filters help bring out detail
and contrast of the planets. Meade offers a
line of inexpensive color filters.
What’s Next? Beyond the Solar System:
Once you have observed our own system of
planets, it’s time to really travel far from
home and look at stars and other objects.
You can observe thousands of stars with
your telescope. At first, you may think stars
are just pinpoints of light and aren’t very
interesting. But look again. There is much
information that is revealed in stars.
The first thing you will notice is that not all
stars are the same colors. See if you can find
blue, orange, yellow, white and red stars.
The color of stars sometimes can tell you
about the age of a star and the temperature
that they burn at.
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?
Almost all the stars you can see in the sky
are part of our galaxy. A galaxy is a large
grouping of stars, containing millions or
even billions of stars. Some galaxies form a
spiral (like our galaxy, the Milky Way) and
other galaxies look more like a large football
and are called elliptical galaxies. There are
many galaxies that are irregularly shaped
and are thought to have been pulled apart
because they passed too close to—or even
through—a larger galaxy.
You may be able to see the Andromeda
galaxy and several others in your telescope.
They will appear as small, fuzzy clouds. Only
very large telescope will reveal spiral or
elliptical details.
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

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.
When you become an advanced observer you
can look for other types of objects such as
asteroids, planetary nebula and globular
clusters. And if you’re lucky, every so often a
bright comet appears in the sky, presenting
an unforgettable sight.
The more you learn about objects in the sky,
the more you will learn to appreciate the

Meade114EQ_AR 4/13/06 4:08 PM Page 13

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
telescopic field of view. This movement is
caused by the rotation of the Earth and
makes an object move through the tele-
scope’s field of view. To keep astronomical
objects centered in the field, simply move
the telescope on one or both of its axes—
vertically and/or horizontally as needed—try
using the telescopes coarse and fine
adjustment controls. At higher powers,
astronomical objects will seem to move
through the field of view of the eyepiece
more rapidly.
sights you see in your telescope. Start
a notebook and write down the
observations you make each night.
Note the time and the date.
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.
Go your library or check out the internet for
more information about astronomy. Learn
about the basics: light years, orbits, star
colors, how stars and planets are formed,
red shift, the big bang, what are the different
kinds of nebula, what are comets, asteroids
and meteors and what is a black hole. The
more you learn about astronomy, the more
fun, and the more rewarding your telescope
will become.
SOME OBSERVING TIPS
Eyepieces: Always begin your observations
using the 25mm low-power eyepiece. The
25mm eyepiece delivers a bright, wide field
of view and is the best to use for most
viewing conditions. Use the high-power 9mm
eyepiece to view details when observing the
Moon and planets. If the image become
fuzzy, switch back down to a lower power.
Changing eyepieces changes the power or
magnification of your telescope.
By the way, you might have noticed
something strange when you looked through
your eyepiece. The image is upside down and
reversed. That means reading words can be
a problem. But it has no affect on
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.

Place the object to be viewed at the edge
of the field and, without touching the
telescope, watch it drift through the field to
the other side before repositioning the
telescope so that the object to be viewed is
again placed at the edge of the field, ready
to be further observed.
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.
Let your eyes “dark-adapt:” Allow five or
ten minutes for your eyes to become “dark
adapted” before observing. Use a red-
filtered flashlight to protect your night vision
when reading star maps, or inspecting the
telescope. Do not use use a regular flash-
light or turn on other lights when observing
with a group of other astronomers. You can
make your own red filtered flashlight by
taping red cellophane over a flashlight lens.
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
and outside air. Also, it is a good idea to
allow your telescope to reach the ambient
(surrounding) outside temperature before
starting an observing session.
When to observe: Planets and other
objects viewed low on the horizon often
lack sharp-ness—the same object, when
observed higher in the sky, will appear
sharper and have greater contrast. Try
reducing power (change your eyepiece) if
your image is fuzzy or shimmers. Keep in
mind that a bright, clear, but smaller image
is more interesting than a larger, dimmer,
fuzzy one. Using too high a power eyepiece is
one of the most common mistakes made by
new astronomers.
Dress Warm: Even on summer nights, the
air can feel cool or cold as the night wears
on. It is important to dress warm or to have
a sweater, jacket, gloves, etc., nearby.
Know your observing site: If possible, know
the location where you will be observing. Pay
attention to holes in the ground and other
obstacles. Is it a location where wild
animals, such as skunks, snakes,
etc., may appear? Are there viewing
obstructions such as tall trees, street
lights, headlights and so forth? The
best locations are dark locations, the
darker the better. Deep space objects are
easiest to see under dark skies. But it is still
possible to observe even in a city.
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.

STAR CHARTS
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
offers AutoStar SuiteTM software. Contact your local
Meade dealer or Meade’s Customer Service department
for more information.
Astronomy and Sky and Telescope magazines print star
charts each month for up-to-the-minute maps of the
heavens.

light travels in the telescope before being
brought to focus in you eyepiece. Your tube is
900mm long.
Primary diameter is how big the mirror is on
your scope. Telescopes are always described
by how large their primary mirror is. Your
telescope is 114mm or 4.5 inches. Other
telescopes are 90mm, 8 inches, 16 inches, or
even 3 feet in diameter. The Hubble
Telescope’s objective mirror has a diameter
of 2.4 meters (that’s 7.8 feet across!).
The focal ratio helps determine how fast the
photographic speed of a telescope is. The
lower the focal ratio number, the faster the
exposure. f/5 is faster than f/10. The faster
the ratio, the faster exposure time is needed
when a camera is hooked up to the
telescope. Your telescope has slower focal
ratio at f/8. Sometimes, astronomers use
focal reducers to make slow exposure
telescopes have faster focal ratios.
USE THE SPECIFICATIONS TO CALCULATE
THE MAGNIFICATION OF YOUR EYEPIECE
The power of a telescope is how much it
magnifies objects. Your 25mm eyepiece
magnifies an object 28 times. Your 9mm
eyepiece magnifies objects 78 times.But if
you obtain other eyepieces, you can calculate
how much magnification they have with your
telescope. Just divide the focal length of the
telescope by the focal length of the eyepiece.

÷
Focal Length of the Eyepiece

Magnification
Look at the specifications. You will see that
the focal length of your scope is 900mm.
Let’s say that you have obtained a 13mm
eyepiece. You can tell that what the focal
length of your eyepiece is as it is always
JOIN AN ASTRONOMY CLUB, ATTEND A STAR PARTY
One of the best ways to increase your knowledge of
astronomy is to join an astronomy club. Check your
local newspaper, school, library, or telescope dealer/
store to find out if there’s a club in your area.
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
Astronomy print schedules for many popular Star
Parties around the United States and Canada.

printed on the side of an eyepiece. Divide:
900 ÷ 13, which equals 69.2. Round this off
to the nearest whole number and your new
eyepiece magnifies objects 69 times.
If you use a Barlow lens with one of your
eyepieces, it doubles the magnification of
your eyepiece. Other types of Barlows can
triple or further increase the power of an
eyepiece. To find out how much your
magnification is when you use a Barlow,
multiply your eyepiece’s magnification
by two.
Your 25mm low-power eyepiece magnifies
an object 28 times. Multiply 28 by 2 and you
get 56 times magnification with a Barlow.

It’s worth repeating: Keep in mind that a
bright, clear, but smaller image is more
interesting than a larger, dimmer, fuzzy one.
Using too high a power eyepiece is one of
the most common mistakes made by new
astronomers. So don’t think that higher
magnification is necessarily better—quite
often the best view is with lower
magnification value!
TAKING CARE OF YOUR TELESCOPE
Your telescope is a precision optical
instrument designed for a lifetime of
rewarding viewing. It will rarely, if ever,
require factory servicing or maintenance.
Follow these guidelines to keep your
telescope in the best condition:
• As with any quality instrument, lens or
mirror surfaces should be cleaned as
infrequently as possible. Front surface
aluminized mirrors, in particular, should
be cleaned only when absolutely
necessary. In all cases avoid touching
any mirror surface. A little dust on the
surface of a mirror or lens causes
negligible loss of performance and
should not be considered reason to clean
the surface. When lens or mirror cleaning
does become necessary, use a camel's
hair brush or compressed air gently to
remove dust. If the telescope's dust
cover is replaced after each observing
session, cleaning of the optics will rarely
be required.
• Fingerprints and organic materials
on the lens or mirror may be
removed with a solution of 3 parts
distilled water to 1 part isopropyl
alcohol. You may also add 1 drop of
biodegradable dishwashing soap per pint
of solution. Use soft, white facial tissues
and make short, gentle strokes. Change
tissues often.
CAUTION: Do not use scented or lotioned
tissues or damage could result to the
optics. DO NOTuse a commercial
photographic lens cleaner.

COLLIMATION (ALIGNMENT)
OF OPTICS
All Meade 114 EQ-AR
telescopes are optically
aligned at the factory prior to
shipment. It is unlikely that you will
need to align, or collimate, the optics
after receipt of the instrument.
However, if the telescope received
unusually rough handling in
shipment, it is possible that the
optics must be re aligned for best
optical performance. In any case this
alignment procedure is simple, and requires
only a few minutes the very first time the
telescope is used. Take the time to
familiarize yourself with the following
collimation procedure, so that you will
recognize a properly collimated instrument
and can adjust the collimation yourself,
if necessary.
A. CORRECT COLLIMATION
The properly collimated (aligned) mirror
system in the Meade 114 EQ-AR assures
the sharpest images possible. This occurs
when the primary mirror and diagonal
mirror are tilted so that the focused image
falls directly through the center of the
focuser drawtube. These mirror tilt
adjustments are made with the diagonal
assembly and the primary mirror cell
(Fig. 11) and will be discussed later.
To inspect the view of the mirror
collimation, look down the
focuser drawtube with the
eyepiece removed. The edge of
the focuser drawtube (1, Fig.
14), will frame the reflections of
the primary mirror with the 3
mirror clips (2, Fig. 14), the
diagonal mirror (3, Fig. 14), the
spider vanes (4, Fig. 14), and
your eye (5, Fig. 14). Properly
aligned, all of these reflections
will appear concentric (i.e., centered)
as illustrated in Fig. 14.
Any deviation from the concentric
reflections will require adjustments to
the diagonal assembly and/or the
primary mirror cell (Fig. 11).
B. DIAGONAL HOLDER
ADJUSTMENTS
If the diagonal mirror (1, Fig. 15) is
centered in the drawtube (2, Fig. 15),
but the primary mirror is only partially
visible in the reflection (3, Fig. 15), the 3
Phillips-head diagonal tilt screws (To adjust
these screws you must first remove an
adhesive backing) must be unthreaded
slightly to the point of where you
can tilt the diagonal holder from
side-to-side by grasping the
diagonal holder with your hand
and tilt until you see the primary
mirror become as centered in the
reflection of the diagonal mirror
as possible. Once you are at the
best position, thread in the 3
Phillips-head diagonal tilt screws
to lock the rotational position.
Then, if necessary, make

adjustments to these 3 Phillips-head screws
to refine the tilt-angle of the diagonal mirror
until the entire primary mirror can be seen
centered within the diagonal mirror
reflecting. When the diagonal mirror is
correctly aligned, it will look like Fig. 14
(Note: The primary mirror is shown out
of alignment).
C. PRIMARY MIRROR ADJUSTMENTS
If the diagonal mirror (1, Fig. 16) and the
reflection of the primary mirror (2, Fig. 16)
appear centered within the drawtube (3, Fig.
16), but the reflection of your eye and the
reflection of the diagonal mirror (4, Fig. 16)
appear off center, you will need to adjust the
primary mirror tilt Phillips-head screws of
the primary mirror cell (3, Fig. 13).
These primary tilt screws are located
behind the primary mirror, at the
lower end of the main tube. To adjust
the primary mirror tilt screws, first
unscrew several turns, the 3 hex-head
primary mirror cell locking screws (2, Fig.
13) that are next to each primary mirror tilt
Phillips-head screw. Then by trial-and-error,
turn the primary mirror tilt Phillips-head
screws (3, Fig. 13) until you develop a feel for
which way to turn each screw to center the
reflection of your eye. Once centered, as in
Fig. 14, turn the 3 hex-head primary mirror
cell locking screws (2, Fig. 13) to relock the
tilt-angle adjustment.
D. STAR TESTING THE COLLIMATION
With the collimation performed, you will
want to test the accuracy of the alignment
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:
• Bring the star image slowly out of focus
until one or more rings are visible around
the central disc. If the collimation was
performed correctly, the central star disk

and rings will be concentric circles,
with a dark spot dead center within
the out-of-focus star disk (this is the
shadow of the secondary mirror), as
shown in Fig. 17C. (An improperly
aligned telescope will reveal elongated
circles (Fig. 17A), with an off-center
dark shadow.)
• If the out-of-focus star disk appears
elongated (Fig. 17A), you will need to
adjust the primary mirror Phillips-head
tilt screws of the primary mirror cell
(3, Fig. 13)
• To adjust the primary mirror tilt screws
(3, Fig. 13), first unscrew several turns
the 3 hex-head primary mirror cell
locking screws (2, Fig. 13), to allow free
turning movement of the tilt knobs.
• Using the flexible cable controls move the
telescope until the star image is at the
edge of the field-of-view in the eyepiece,
as in Fig. 17B.
•As you make adjustments to the primary
mirror tilt screws (3, Fig. 13), you will
notice that the out-of-focus star disk
image will move across the eyepiece field.
Choose one of the 3 primary mirror tilt
screws and slightly move the shadow to
the center of the disk. Then slightly move
the telescope using the flexible cable
controls to center the star disk image in
the center of the eyepiece.
• If any further adjustments are necessary,
repeat this process as many times as
needed until the out-of-focus star disk
appears as in Fig. 17C, when the star
disk image is in the center of the
eyepiece field.
• With the star testing of the collimation
complete, tighten the 3 hex-head primary
mirror locking screws (2, Fig. 13)
