2. Installation
Attaching the R.A. GoTo Motor
Remove the telescope tube, counterweight, and counter-
weight shaft from the SkyView Pro mount before attaching the
motor drives.
1. Remove the R.A. motor cover from the mount by loosen-
ing the Phillips head screw on the bottom of the cover
(Figure2). Slide the cover off the mount.
2. Remove the R.A. slow-motion control knob from the R.A.
worm gear shaft. The slow-motion knob will not be usable
once the SkyView Pro GoTo system has been installed.
All slow-motion adjustments will be made using the GoTo
hand controller.
3. The R.A. GoTo motor assembly is identified by the
4-pin rectangular connector attached to the motor body
(Figure3). The motor will be attached to the mount by a
40mm long socket-head cap screw that goes through the
hole in the rear of the equatorial mount, just above the rear
latitude adjustment L-bolt (Figure 4). It will be helpful to
remove the rear latitude adjustment L-bolt while installing
Congratulations on your purchase of the Orion SkyView Pro GoTo system. The GoTo system will add brains to
your SkyView Pro equatorial mount’s brawn. Once the GoTo system has been installed, it enables you to locate and automati-
cally slew to thousands of celestial objects using the included hand controller. Views of the planets, Moon, galaxies, nebulae,
stars, and star clusters will all be as close as the touch of a button.You’ll nd using your SkyView Pro GoTo mount will provide an
entirely new astronomical experience that will open up new realms of celestial exploration.
These instructions will help you install and properly use the SkyView Pro GoTo system. Please read them over thoroughly before
getting started. It may take a few observing sessions to become familiar with all the features of the SkyView Pro GoTo system, so
keep this manual handy as you master your mount’s operation.

the R.A. GoTo motor. Place one of the 10mm at wash-
ers onto the R.A. motor attachment screw. Attach the R.A.
motor attachment screw to the end of a 4mm hex key and
push it up through the hole in the rear of the equatorial
mount (Figure 4). Hold the R.A. GoTo drive in your hand
so its threaded hole meets the screw as it comes out the
other end of the hole. Thread the screw into the threaded
hole of the R.A. motor assembly until secure, but do not
overtighten. You will need to make small adjustments to
the motor position in the following steps.
4. Slide the geared end of one of the small brass gears onto
the worm gear shaft so it resembles Figure 5. Rotate the
small brass gear so that one of the setscrews will press
against the at part of the R.A. worm gear shaft. Secure
the small brass gear by tightening the setscrews with the
included 2mm hex key, but do not overtighten. You may
have to make small adjustments to the gear’s position in
the following step to ensure proper gear engagement.
5. Make certain that the teeth of the smaller motor assem-
bly gear correctly mesh with the teeth of the brass gear
(Figure 6). Also, make certain the gears are not too tightly
pressed together.You may have to adjust the way the gears
mesh by tightening or loosening the socket-head cap screw
that is used to attach the R.A. GoTo motor assembly to the
mount and/or the small setscrews on the brass gear. If the
gears are not meshed correctly or are too tightly pressed
together, then the drive will not track properly, or at all. This
attachment process is tricky, and it may take several adjust-
ments before the gears properly mesh.
6. Take the R.A. GoTo motor cover and hold it near the
installed R.A. GoTo motor. On the inside of the motor
cover, you will see a set of wires with a white 4-pin rectan-
gular connector attached. Carefully connect the 4-pin rect-
angular connector attached to the R.A. GoTo motor cover
to the corresponding 4-pin rectangular connector on the
R.A. GoTo motor. Once connected, the wiring of your R.A.
GoTo motor should resemble Figure 7.
Note: Inside the R.A. GoTo motor cover you will nd an addi-
tional set of wires connected to each other with 5-pin rectan-
gular connectors. Make certain these wires are connected
before proceeding to step 7.
7. Once the rectangular connector has been attached, you
can install and secure the R.A. GoTo motor cover with the
10mm long Phillips head screw. Don’t forget to re-install
the rear latitude adjustment L-bolt if you have removed it
previously.

Note: There is a small packet of grease included with your
SkyView Pro GoTo system. Once you have installed the GoTo
motor so the gears mesh properly, you can apply a very
small amount of the included grease to the meshed gears to
ensure optimal gear mating.
Attaching the Dec. GoTo Motor
Before attaching the Dec. GoTo motor drive, the telescope
tube must be removed from the equatorial mount.
1. Remove the Dec. slow-motion control knob from the Dec.
worm gear shaft. The Slow-motion knob will not be usable
once the SkyView Pro GoTo system has been installed.
All slow-motion adjustments will be made using the GoTo
hand controller.
2 Using the supplied Phillips-head screwdriver remove the
Dec. Motor cover from the Dec. motor assembly (Figure
9). Once the screws have been removed pull the cover
off the motor. There will be some friction resistance but it
should pull off by hand. Save the cover and screws in a
safe place to reinstall after the motor is attached.
3. Slide the geared end of the remaining small brass gear
onto the Dec. worm gear shaft of your SkyView Pro mount

so it resembles Figure 8. Rotate the small brass gear so
that one of the setscrews will press against the at part of
the Dec. worm gear shaft. Secure the small brass gear by
tightening the setscrews with the included 2mm hex key,
but do not overtighten.You may have to make small adjust-
ments to the gear’s position in the following step to ensure
proper gear engagement.
4. The Dec. GoTo motor assembly is identied by its black,
rectangular body (Figure 10). It is attached to the equato-
rial mount using the Dec. GoTo motor attachment screw
that goes through the hole in the ange at the top of the
equatorial mount (Figure 11). The motor assembly should
attached so that it is oriented as shown in Figure 12. Hold
the motor assembly so that its threaded hole lines up with
the hole in the top of the mount. Place the lock washer and
then a at washer onto the Dec. GoTo motor attachment
screw. Use the 4mm hex key to thread the attachment
screw into the motor assembly attachment hole until it is
secure, but do not overtighten.
5. Make certain that the teeth of the smaller gear of the Dec.
GoTo motor assembly meshes with the brass gear. Also,
make certain the gears are not too tightly pressed togeth-
er. You can adjust the way the gears mesh by tightening
or loosening the socket-head cap screw that is used to
attach the Dec. GoTo motor assembly to the mount and/or
the small setscrews on the brass gear. If the gears are not
meshed correctly or are too tightly pressed together, then
the drive will not track properly, or at all. This attachment
process is tricky, and it may take several adjustments
before the gears properly mesh.
Note: There is a small packet of grease included with your
SkyView Pro GoTo system. Once you have installed the GoTo
motor so the gears mesh properly, you can apply a very
small amount of the included grease to the meshed gears to
ensure optimal gear mating.
6. Once the Dec. GoTo motor and gear have been installed
and the gears mesh appropriately, you can install and
secure the Dec. GoTo motor cover with the two 8mm long
Phillips screws. Once you have installed the Dec. GoTo
motor and cover, your mount should resemble Figure 13.
Attaching the Motor Control Box
Once both of the GoTo motors have been installed, you can
attach and connect the motor control box.
1. Attach the motor control box bracket to the top of one of
the legs of the SkyView Pro tripod. It will be most conve-
nient to attach the bracket to the leg closest to the side
of the R.A. GoTo motor cover with the two 8-pin circular
jacks.
2. Slide the motor control box into the motor control box
bracket.
3. Connect one end of the motor cable to the 8-pin circular
jack marked “R.A. IN” on the R.A. GoTo motor cover.
4. Connect the other end of the motor cable to the 8-pin cir-
cular jack on the motor control box.
5. Connect one end of the motor cable to the 8-pin circular
jack marked “Dec. OUT” on the R.A. GoTo motor cover.

Attaching the GoTo Hand Controller
1. Strap the included hand controller bracket to a tripod leg
above the tripod center support tray using the hook-and-
loop strap, as shown in Figure 14.
2. The SkyView Pro GoTo hand controller cable is a 30" long
coiled cable with modular connectors (RJ-45) on both
ends. Connect one end of the coiled cable to the modular
jack on the motor control box marked “Hand Controller.”
3. Connect the other end of the coiled cable to the hand con-
troller modular jack (Figure 15).
Your SkyView Pro GoTo system is now installed and should
resemble the image on the manual cover. You can now pro-
ceed to power the system and utilize the many functions of
the GoTo hand controller.
3. The SynScan GoTo
HandController
Once aligned, the GoTo hand controller and dual-axis GoTo
motors and encoders allow you to automatically point your
SkyView Pro mounted telescope at a specic object, or tour
the skies with pushbutton simplicity. The user-friendly menu
allows automatic slewing to over 42,000 p 3objects. Even
inexperienced astronomers will nd themselves quickly mas-
tering the variety of features the GoTo hand controller offers in
just a few observing sessions.
For more information about the features and functionality
of the SynScan GoTo Hand Controller, refer to the separate
manual for the controller.
Powering the SkyView Pro GoTo System
The SkyView Pro GoTo system should be powered by a 12V
(11V-15V) DC power supply (tip positive) capable of produc-
ing continuous current of a minimum 2 amps. We recommend
using a portable rechargeable battery, like the Dynamo Pro
available from Orion, or an AC-to-12V DC power adapter with
2-amp current rating.
If you are using a portable battery like the Orion Dynamo, use
the 12V DC power cable supplied with your mount (male ciga-
rette lighter plug on one end, standard 12V DC power plug on
other end) to connect the battery to the 12V DC power jack on
the motor control box. Make sure the Dynamo’s power switch
is in the “on” position after connecting. Then, to turn the GoTo
system on, simply press the switch on the motor control box
so it is in the “on” position.
