Congratulations on your purchase of a quality Orion mount. Your new SkyView Pro Equatorial Mount
was developed to work with many different telescope optical tubes. Designed for astronomical use, this
precision mount allows convenient “tracking” of celestial objects as they move slowly across the sky, so
they remain within your eyepiece’s field of view. The setting circles built into the mount will assist you in
locating hundreds of fascinating celestial denizens, including galaxies, nebulas, and star clusters, from
their catalogued coordinates. With a little practice, you’ll find that the SkyView Pro Equatorial Mount is an
invaluable tool for getting the most out of your astronomical observing sessions.
These instructions will help you set up and properly use your equatorial mount. Please read them over
thoroughly before getting started.

1. Unpacking
Figure 2. Orient the equatorial mount so that the post on the
tripod head lines up with the azimuth adjustment knobs on the
equatorial mount.
The entire mount will arrive in one box. Be careful unpacking
the box.We recommend keeping the box and original packag-
ing. In the event that the mount needs to be shipped to anoth-
er location, or returned to Orion for warranty repair, having the
proper packaging will help ensure that your mount will survive
the journey intact.
3. Assembly
1. Stand the tripod upright and spread the legs out as far as
they will go. Keep the tripod legs at their shortest (fully
retracted) length, for now; you can extend them to a more
desirable length later, after the scope is fully assembled.
Make sure all the parts in the Parts List are present. Be sure to
check box carefully, as some parts are small. If anything appears
to be missing or broken, immediately call Orion Customer
Support (800-676-1343) or email [email protected] for
assistance.
2. Place the base of the equatorial mount onto the tripod
head. Orient the equatorial mount so that the post on the
tripod head lines up with the azimuth adjustment knobs on
the equatorial mount (Figure 2). You may need to loosen
the azimuth adjustment knobs on the equatorial mount in
order to fit the mount onto the tripod head.

5. Remove the knob and washer from the bottom of the cen-
ter support shaft. Slide the tripod support tray up the bot-
tom of the central support shaft until the three tray arms
are touching the legs of the tripod. The flat side of the
accessory tray should be facing up. Make sure the “V” of
each tray arm is against a tripod leg. Place the knob wash-
3
er on the center support shaft against the tray, and follow
it by threading the securing knob all the way up the center
support shaft until it is tight against the tray. The tripod
support tray provides additional stability for the tripod, and
holds up to five 1.25" eyepieces and two 2" eyepieces.
6. Thread the counterweight shaft into the equatorial mount
at the base of the declination axis until tight. Make sure the
casting at the top is threaded clockwise as far as it will go
before attaching the shaft. Then turn the casting counter-
clockwise one the shaft is installed until the top of the cast-
ing is flush with the mount.

7. Remove the knurled “toe saver” retaining screw on the
bottom of the counterweight shaft and slide both counter-
weights onto the shaft. Make sure the counterweight lock
knobs are adequately loosened to allow the counterweight
shaft to pass through the hole. Position the counterweights
about halfway up the shaft and tighten the lock knobs.
Replace the toe saver at the end of the bar. The toe saver
prevents the counterweights from falling on your foot if the
lock knobs happen to come loose.

Figure 3. Proper operation of the equatorial mount requires that
the telescope tube be balanced on both the R.A. and Dec. axes. (a)
With the R.A. lock lever released, slide the counterweights along the
counterweight shaft until it just counterbalances the tube. (b) When
you let go with both hands, the tube should not drift up or down. (c)
With the Dec. lock knob released, loosen the tube ring lock clamps
a few turns ands slide the telescope forward or back in the tube
rings. (d) When the tube is balanced about the Dec. axis, it will not
move when you let go.
8. Attach the slow-motion control knobs to the right ascen-
sion and declination gear shafts of the equatorial mount
by sliding them onto the shafts. Line up the flat end of the
gear shaft with the interior of the knob. The knobs can be
attached to either end of the shafts, whichever is more
convenient for you.
Your SkyView Pro EQ mount is now fully assembled and
should resemble Figure 1.
3. Open the tube rings and lay the telescope optical tube in
the rings at about the midpoint of the tube’s length. Rotate
the tube so that the focuser is at a convenient height for
viewing. Close the tube rings and tighten them.
4. Attaching a Telescope
The SkyView Pro equatorial mount is designed to hold tele-
scope tubes weighing up to approximately 20 lbs. For heavier
telescopes, the mount may not provide sufficient stability for
steady imaging. Any type of telescope can be mounted on the
SkyView Pro, including refractors, Newtonian reflectors, and
catadiotropics, provided a set of tube rings is available to cou-
ple the tube to the mount. Orion sells a variety of telescope
tube rings. Please visit our website at telescope.com for
details.
5. Balancing a Telescope
To ensure smooth movement of the telescope on both axes of
the equatorial mount, it is imperative that the optical tube is
properly balanced. We will first balance the telescope with
respect to the right ascension axis, then the declination axis.
1. Keeping one hand on the telescope optical tube, loosen
the R.A. lock lever. Make sure the Dec. lock lever is locked,
for now. The telescope should now be able to rotate freely
about the right ascension axis. Rotate it until the counter-
weight shaft is parallel to the ground (i.e., horizontal).
1. Attach the tube mounting rings to the tube mounting plate
using the attachment screws that came with tube rings.
The screws should go through the holes on the outer ends
of the mounting plate and rethread into the tube rings.
Note that the side of the mounting plate with the central
“groove” will be facing up.
2. Now loosen both counterweight lock knobs and slide the
weights along the shaft until they exactly counterbalance
the telescope (Figure 3a). That’s the point at which the
shaft remains horizontal even when you let go with both
hands (Figure 3b). If the telescope refuses to balance,
then you have either too much or too little counterweight.
Remove a counterweight if it is too much, or add optional
counterweights if it is too little.
2. Loosen the black mounting plate securing knob as well as
the metal safety screw on the top of the equatorial mount.
Place the mounting plate, with the tube rings attached, in
the dovetail slot on top of the equatorial mount. Position
the mounting plate so that it is centered on the dovetail
slot. Re-tighten the mounting plate securing knob until the
mounting plate is secure. Then, tighten the safety screw.
The safety screw will ensure that the mounting plate (and
telescope tube) will not fall off the EQ mount if the mount-
ing plate securing knob should come loose.
3. Retighten the counterweight lock knobs. The telescope is
now balanced on the right ascension axis.

5. With one hand on the telescope optical tube, loosen the
Dec. lock lever.The telescope should now be able to rotate
freely about the Dec. axis. Loosen the tube ring clamps a
few turns, until you can slide the telescope tube forward
and back inside the rings. (this can be aided by using a
slight twisting motion on the optical tube while you push or
pull on it). (Figure 3c).

6. Position the telescope in the tube rings so it remains hori-
zontal when you carefully let go with both hands. This is
the balance point for the optical tube with respect to the
Dec. axis (Figure 3d).
Figure 5. To find Polaris in the night sky, look north and find the
Big Dipper. Extend an imaginary line from the two "Pointer Stars" in
the bowl of the Big Dipper. Go about five times the distance
between those stars and you'll reach Polaris, which lies within 1° of
the north celestial pole (NCP).
7. Retighten the knurled ring clamps.
The telescope is now balanced on both axes. When you
loosen the lock lever on one or both axes and manually point
the telescope, it should move without resistance and should
not drift from where you point it.
Polar Alignment
For Northern Hemisphere observers, approximate polar align-
ment is achieved by pointing the mount’s right ascension axis
at the North Star, or Polaris. It lies within 1° of the north celes-
tial pole (NCP), which is an extension of the Earth’s rotational
axis out into space. Stars in the Northern Hemisphere appear
to revolve around the NCP.
6. Setting Up and Using the
Equatorial Mount
When you look at the night sky, you no doubt have noticed
that the stars appear to move slowly from east to west over
time. That apparent motion is caused by the Earth’s rotation
(from west to east). An equatorial mount (Figure 4) is
designed to compensate for that motion, allowing you to easi-
ly “track” the movement of astronomical objects, thereby
keeping them from drifting out of your telescope’s field of view
while you’re observing.
To find Polaris in the sky, look north and locate the pattern of
the Big Dipper (Figure 5). The two stars at the end of the
“bowl” of the Big Dipper point right to Polaris.
Observers in the Southern Hemisphere aren’t so fortunate to
have a bright star so near the south celestial pole (SCP). The
star Sigma Octantis lies about 1° from the SCP, but it is bare-
ly visible with the naked eye (magnitude 5.5).
For general visual observation, an approximate polar align-
ment is sufficient.
This is accomplished by slowly rotating the telescope on its
right ascension (R.A.) axis, using only the R.A. slow-motion
knob. But first the R.A. axis of the mount must be aligned with
the Earth’s rotational (polar) axis—a process called polar
alignment.

three tripod legs.

adjustment knobs above it are used to make small adjustments to the
mount’s azimuth position. Be certain to loosen the tripod attachment
knob on the central support shaft before adjusting these knobs.
2. There are two latitude adjusting L-bolts (see Figure 4);
loosen one while tightening the other. By doing this you
will adjust the latitude of the mount. Continue adjusting the
mount until the pointer on the latitude scale is set at the
latitude of your observing site. If you don’t know your lati-
tude, consult a geographical atlas to find it. For example, if
your latitude is 35° North, set the pointer to 35. The lati-
tude setting should not have to be adjusted again unless
you move to a different viewing location some distance
away.

cal tube until it is parallel with the right ascension axis, as
it is in Figure 4.
thread the polar axis finder scope into the equatorial mount
until tight.
4. Move the tripod so the telescope tube and right ascension
axis point roughly at Polaris. If you cannot see Polaris
directly from your observing site, consult a compass and
rotate the tripod so the telescope points north. There is a
label bearing a large “N” at the base of the equatorial
mount (Figure 6). It should be facing north.
Alignment of the Polar Axis Finder Scope
1. Loosen the Dec. lock lever and rotate the optical tube on
the declination axis so that the tube is at a 90° to the right
ascension axis (Figure 8). Tighten the Dec. lock lever.
2. Look through the polar finder at a distant object (during
the day) and center it in the crosshairs. You may need to
adjust the latitude adjustment L-bolts and the tripod posi-
tion to do this.
The equatorial mount is now polar aligned for casual observ-
ing. More precise polar alignment is recommended for
astrophotography. For this we recommend using the optional
polar axis finder scope
3. Rotate the mount 180° about the R.A. axis. Again, it may
be convenient to remove the counterweights and optical
tube first.
From this point on in your observing session, you should not
make any further adjustments to the latitude of the mount, nor
should you move the tripod. Doing so will undo the polar align-
ment. The telescope should be moved only about its R.A. and
Dec. axes.
4. Look through the polar finder again. Is the object being
viewed still centered on the crosshairs? If it is, then no fur-
ther adjustment is necessary. If not, then look through the
polar finder while rotating the mount about the R.A. axis.
You will notice that the object you have previously cen-
tered moves in a circular path. Use the three alignment
setscrews on the polar axis finder to redirect the cross-
hairs of the polar finder to the apparent center of this cir-
cular path. Repeat this procedure until the position that the
crosshairs point to does not rotate off-center when the
mount is rotated in R.A. Once this is accomplished,
retighten the thumbscrews.
Polar Alignment Using an Optional Polar Axis
Finder Scope
The SkyView Pro EQ mount can be equipped with an option-
al polar axis finder scope (Figure 7a) housed inside the right
ascension axis of the mount. When properly aligned and
used, it makes accurate polar alignment quick and easy to do.
To install the polar axis finder scope, remove the cap at the
base of the mount’s right ascension axis (Figure 7b) and
6
indicate the general positions of Cassiopeia and the Big
Dipper relative to the north celestial pole (which is indicat-
ed by the cross at the center of the reticle). Rotate the ret-
icle so the constellations depicted match their current ori-
entation in they sky when viewed with the naked eye. To
do this, release the R.A. lock lever and rotate the main tel-
escope around the R.A. axis until the reticle is oriented
with sky. For larger optical tubes, you may need to remove
the tube from the mount to prevent it from bumping into
the mount. Once the reticle is correctly oriented, use the
right ascension lock lever to secure the mount’s position.
5. Now use the azimuth adjustment knobs (Figure 2) and the
latitude adjustment L-bolts (Figure 4) on the mount to
position the star Polaris inside the tiny circle marked
“Polaris” on the finder’s reticle. You must first loosen the
knob underneath the equatorial mount on the center sup-
port shaft to use the azimuth adjustment knobs. Once
Polaris is properly positioned within the reticle, you are
precisely polar aligned.
If you do not have a clear view of Polaris from your observing
site, you will not be able to use the polar-axis finder to pre-
cisely polar align the telescope.
Figure 8. The optical tube must be at a 90° angle to the right
Note: From this point on in your observing session, you
should not make any further adjustments in the azimuth
or the latitude of the mount, nor should you move the tri-
pod. Doing so will undo the polar alignment. The tele-
scope should be moved only about its right ascension
and declination axes.
ascension axis in order to view through the polar axis finder
The polar axis finder scope is now ready to be used. When
not in use, replace the plastic protective cover to prevent the
polar finder from getting bumped, which could knock it out of
alignment.
Use of the Right Ascension and Declination
Slow-Motion Control Knobs
Using the Polar Axis Finder Scope
The right ascension (R.A.) and declination (Dec.) slow-motion
control knobs allow fine adjustment of the telescope’s position
to center objects within the field of view. Before you can use
the knobs, you must manually “slew” the mount to point the
telescope in the vicinity of the desired target. Do this by loos-
ening the R.A. and Dec. lock levers and moving the telescope
about the mount’s right ascension and declination axes. Once
the telescope is pointed close to the object to be viewed,
retighten both lock levers.
The reticle of the polar axis finder scope for the SkyView Pro
has a tiny star map printed on it that makes precise polar
alignment quick and easy. To align the mount using the polar
axis finder scope, follow these instructions:
1. Approximately polar-align the mount as outlined in the
previous procedure.
2. Loosen the Dec. lock lever and rotate the optical tube on
the declination axis so that the tube is at a 90° to the right
ascension axis (Figure 8). Tighten the Dec. lock lever.
Note: If you have an optional motor drive attached you
will need to loosen the manual clutch on the R.A. (and
Dec. for dual-axis drives) gear shaft before using the
slow-motion control knob.
3. Remove the cap on the front opening of the mount (Figure
4). Focus the polar finder by rotating its eyepiece. Now,
sight Polaris in the polar axis finder scope. If you have fol-
lowed the approximate polar alignment procedure accu-
rately, Polaris will probably be within the field of view. If
not, move the tripod left-to-right, and adjust the latitude
up-and down until Polaris is somewhere within the field of
view of the polar axis finder scope.
The object should now be visible somewhere in the tele-
scope’s finder scope. If it isn’t, use the slow-motion knobs to
scan the surrounding area of sky. When the object is visible in
the finder scope, use the slow-motion knobs to center it. Now,
look in the telescope’s eyepiece. If the finder scope is proper-
ly aligned, the object should be visible somewhere in the field
of view. Once the object is visible in the eyepiece, use the
slow-motion knobs to center it in the field of view.
4. Shine a red flashlight down the front end of the polar find-
er to illuminate the reticle within the field of view. Make
sure the flashlight shines in at an angle, so as not to block
the polar finder’s field of view. It may be helpful to have a
friend hold the flashlight while you look through the polar
finder. Note the constellation Cassiopeia and the Big
Dipper in the reticle. They do not appear in scale, but they
Tracking Celestial Objects
When you observe a celestial object through the telescope,
you’ll see it drift slowly across the field of view. To keep it in

That’s 5 hours and 35.4 minutes in right ascension, and -5

minutes in 1 degree of declination).

the field, if your equatorial mount is polar aligned, just turn the
R.A. slow-motion control knob clockwise. The Dec. slow-
motion control knob is not needed for tracking. Objects will
appear to move faster at higher magnifications, because the
field of view is narrower.
1. Identify a bright star in the sky near the celestial equator
(declination = 0°) and look up its coordinates in a star
atlas.
2. Loosen the R.A. and Dec. lock levers on the equatorial
mount, so the telescope optical tube can move freely.
Optional Motor Drives for Automatic Tracking
3. Point the telescope at the bright star whose coordinates
you know. Lock the R.A. and Dec. lock levers.
An optional DC motor drive can be mounted on the R.A. axis
of the equatorial mount to provide hands-free tracking.
Objects will then remain stationary in the field of view without
any manual adjustment of the right ascension slow-motion
control knob.
4. Loosen one of the R.A. setting circle thumbscrews (see
Figure 9; this will allow the setting circle to rotate freely.
Rotate the setting circle until the R.A. pointer arrow indi-
cates the R.A. coordinate listed in the star atlas for the
object. Re-tighten the setting circle thumbscrew.
Understanding the Setting Circles
The setting circles on an equatorial mount enable you to
locate celestial objects by their “celestial coordinates”. Every
object resides in a specific location on the “celestial sphere”.
That location is denoted by two numbers: its right ascension
(R.A.) and declination (Dec.). In the same way, every location
on Earth can be described by its longitude and latitude. Right
ascension is similar to longitude on Earth, and declination is
similar to latitude. The R.A. and Dec. values for celestial
objects can be found in any star atlas or star catalog.
Finding Objects With the Setting Circles
Now that both setting circles are calibrated, look up in a star
atlas the coordinates of an object you wish to view.
1. Loosen the Dec. lock lever and rotate the telescope until
the declination value from the star atlas matches the read-
ing on the Dec. setting circle. Remember that values of the
Dec. setting circle are positive when the telescope is point-
ing north of the celestial equator (Dec. = 0°), and negative
when the telescope is pointing south of the celestial equa-
tor. Retighten the lock lever.
The R.A. setting circle is scaled in hours, from 1 through 24,
with small marks in between representing 10-minute incre-
ments (there are 60 minutes in 1 hour of right ascension).The
lower set of numbers apply to viewing in the Northern
Hemisphere, while the numbers above them apply to viewing
in the Southern Hemisphere. The location of the right ascen-
sion coordinate indicator arrow is shown in Figure 9.
2. Loosen the R.A. lock lever and rotate the telescope until
the right ascension value from the star atlas matches the
reading on the R.A. setting circle. Remember to use the
upper set of numbers on the R.A. setting circle. Retighten
the lock lever.
The Dec. setting circle is scaled in degrees, with each mark
representing 2° increments. Values of declination coordinates
range from +90° to -90°. The 0° mark indicates the celestial
equator. When the telescope is pointed north of the celestial
equator, values of the declination setting circle are positive;
when the telescope is pointed south of the celestial equator,
values of the declination setting circle are negative.
Most setting circles are not accurate enough to put an object
dead-center in the telescope’s eyepiece, but they should
place the object somewhere within the field of view of the
finder scope, assuming the equatorial mount is accurately
polar aligned. Use the slow-motion controls to center the
object in the finder scope, and it should appear in the tele-
scope’s field of view.
So, the coordinates for the Orion Nebula listed in a star atlas
will look like this:
The setting circles must be re-calibrated every time you wish
to locate a new object. Do so by calibrating the setting circles
for the centered object before moving on to the next one.

Dec. lock lever and rotate the telescope until it is pointing
straight overhead. The counterweight shaft is still horizontal.
Then retighten both lock levers.
What if you need to aim the telescope directly north, but at an
object that is nearer to the horizon than Polaris? You can’t do
it with the counterweights down as pictured in Figure 1. Again,
you have to rotate the scope in right ascension so that the
counterweight shaft is positioned horizontally. Then rotate the
scope in declination so it points to where you want it near the
horizon.
a.
b.
To point the telescope directly south, the counterweight shaft
should again be horizontal. Then you simply rotate the scope
on the declination axis until it points in the south direction.
To point the telescope to the east or west, or in other direc-
tions, you rotate the telescope on its right ascension and dec-
lination axes. Depending on the altitude of the object you want
to observe, the counterweight shaft will be oriented some-
where between vertical and horizontal.
Figure 10 illustrates how the telescope will look when pointed
at the four cardinal directions: north, south, east and west.
c.
d.
The key things to remember when pointing the telescope are
that a) you only move it in right ascension and declination, not
in azimuth or latitude (altitude), and b) the counterweight and
shaft will not always appear as it does in Figure 1. In fact it
almost never will!
Figure 10. This illustration show the telescope pointed in the the
four cardinal directions (a) north, (b) south, (c) east, (d) west. Note
that the tripod and mount have ot been moved; only the telescope
tube has been moved on the R.A. and Dec. axes.
Confused About Pointing the Telescope?
7. Specifications
Beginners occasionally experience some confusion about
how to point the telescope overhead or in other directions. In
Figure 1 the telescope is pointed north as it would be during
polar alignment. The counterweight shaft is oriented down-
ward. But it will not look like that when the telescope is point-
ed in other directions. Let’s say you want to view an object
that is directly overhead, at the zenith. How do you do it?
