The motor drive system also features a push button hand controller that can move the telescope along the right ascension (R.A.) and declination (Dec.) axes at speeds of 2x, 4x and 8x the sidereal rate.This provides an easy way to center objects in the eyepiece. The Dual-Axis motor drive system is also necessary for doing long-exposure astrophotography.The electronic hand controller allows positional corrections to be made to both the R.A. and Dec. axes of the mount during an astrophotographic exposure. Attaching the R.A. Motor R.A. motor Drive cover Remove the telescope tube, counterweight, and counterweight shaft from the 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 1). Slide the cover off the mount. 2. The R.A. motor assembly is identified by its silver colored cylindrical body (Figure 2). It will be attached to the mount Phillips-head by a socket-head cap screw that goes through the hole in screw the rear of the equatorial mount, just above the rear latitude adjustment L-bolt (Figure 3). Attach the 4mm socket-head cap screw to the end of a 4mm hex key and push it up through the hole in the rear of the equatorial mount. Hold the R.A. drive in your hand so that its threaded hole meets up with 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. Figure 1. The R.A. motor cover.

B 02/09 R.A. worm gear shaft Brass gear of R.A. motor assembly Hole Figure 3. The motor is attached to the front of the mount by a sockethead cap screw pushed up through the hole in the rear of the mount. This attachment process is tricky, and it may take you several tries before you get it right. 3. Remove the R.A. slow-motion control knob from the R.A. worm gear shaft if it is on the side of the mount that the motor assembly’s brass gear is on, and attach it to the opposite end of the worm gear shaft. 4. Slide the open end of the manual clutch assembly (Figure 4) onto the worm gear shaft. Rotate the manual clutch Figure 4. The manual clutch assembly. Brass gear Thumbwheel Setscrew Open end assembly so that the setscrew will press against the flat in the R.A. worm gear shaft. Secure the manual clutch assembly by tightening the setscrew with a 2mm hex key. 5. Make certain that the teeth of the motor assembly gear mesh with the teeth of the manual clutch assembly gear. Also, make certain the gears are not too tightly pressed together. You can adjust the way the gears mesh by tightening or loosening the socket-head cap screw that is used to attach the R.A. motor assembly to the mount. If the gears are not meshed correctly or are too tightly pressed together, then the drive will not track properly, or at all. When finished, the assembled R.A. drive should resemble Figure 5.You can now replace the R.A. motor cover and secure it with the Phillips head screw. Please note that if you wish to use the slow-motion control knob to move the telescope in R.A. with the R.A. motor drive attached, you must first loosen the thumbwheel on Figure 5. The assembled R.A. motor drive. the manual clutch assembly. Failure to do so may result in damage to the motor. Attaching the Dec. Motor Drive Before attaching the Dec. motor drive, the telescope tube must be removed from the mount. 1. The Dec. motor assembly is identified by its black, cylindrical body (Figure 6). It is attached to the equatorial mount with the 5mm socket-head cap screw that goes through the hole in the flange at the top of the equatorial mount (Figure 7). The motor assembly should be attached so that it is oriented as shown in Figure 8. Hold the motor assembly so that its threaded hole lines up with the hole in the Modular jack Threaded hole Brass gear Figure 6. The Dec. motor assembly. top of the mount. Thread the screw with a 5mm hex key through the mount and into the motor assembly. Thread the screw into the motor assembly until it is secure, but do not overtighten. 2. Remove the Dec. slow-motion control knob if it is on the end of the Dec. worm gear shaft closest to the Dec. motor assembly gear. Attach the slow motion knob to the opposite end of the worm gear shaft. Flange Hole Figure 7. The location of the flange on the mount. 3.
