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 automatically 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 find 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.

Parts List

Installation

Attaching the R.A. GoTo Motor
Remove the telescope tube, counterweight, and counterweight shaft from the SkyView Pro mount before attaching the motor drives.

1. Remove the R.A. motor cover from the mount by loosening the Phillips head screw on the bottom of the cover (Figure 2). Slide the cover of 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 the R.A. GoTo motor. Place one of the 10mm flat washers 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 flat 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. ake certain that the teeth of the smaller motor assembly 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 do not mesh 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.

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  rectangular connector attached. Carefully connect the 4-pin rectangular 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 find an additional set of wires connected to each other with 5-pin rectangular 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.

•  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.

• 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.

• 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 flat 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 adjustments to the gear’s position in the following step to ensure proper gear engagement.

• The Dec. GoTo motor assembly is identified by its black, rectangular body (Figure 10). It is attached to the equatorial mount using the Dec. GoTo motor attachment screw that goes through the hole in the flange at the top of the equatorial mount (Figure 11). The motor assembly should be 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 flat 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.

• Make certain that the teeth of the smaller gear of the Dec. GoTo motor assembly mesh with the brass gear. Also, make certain the gears are not too tightly pressed together- 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 do not mesh 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.

• 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 convenient 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 circular 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.
6. Connect the other end of the motor cable to the 8-pin cir­cular jack on the Dec. GoTo motor.

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-and­loop 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 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 con­troller modular jack (Figure 15).
   

Your SkyView Pro GoTo system is now installed and should resemble the image on the manual cover. You can now pro­ceed 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 specific object, or tour the skies with pushbutton simplicity. The user- friendly menu allows automatic slewing to over 42,000 objects. Even inex­perienced astronomers will find themselves quickly mastering 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 produc­ing a continuous current of a minimum of 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 a 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 ciga­rette lighter plug on one end, standard 12V DC power plug on another 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.
