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 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 mount, so keep this manual handy as you master your mount’s operation. Figure 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 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 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. Make 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 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. 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 find an addi- tional set of wires connected to each other with 5-pin rect- angular 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. Figure 4.
