Orion TrueTrack Dual-Axis DC Motor Drive System
#7832
Thank you for your purchase of an Orion TrueTrack motor drive system. The TrueTrack allows convenient hands-free sidereal tracking of the night sky for SkyView Pro mounted telescopes. The motor drive sys- tem 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 elec- tronic 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 Drive
Remove the telescope tube, counterweight, and counter- weight 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 by a socket-head cap screw that goes through the hole in the rear of the equatorial mount, just above the rear lati- tude 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.
