User manual ORION TELESCOPES & BINOCULARS TRUETRACKSINGLEAXIS

[. . . ] This provides an easy way to center objects in the eyepiece. The TrueTrack single-axis drive is also a useful component for doing short and medium-exposure astrophotography. The electronic hand controller allows positional corrections to be made in the right ascension (R. A. ) during an astrophotographic exposure. Motor Drive Remove the telescope tube, counterweight, and counterweight shaft from the mount before attaching the motor drive. [. . . ] Rotate the manual clutch assembly so that the setscrew will press against the flat on the R. A. Secure the manual clutch assembly by tightening the setscrew with a 2mm Allen wrench. motor drive. Using the Velcro Two strips of velcro (one strip of "hooks" and one strip of "loops") have been provided so you can create a place to keep the hand controller out of the way when not in use. Place the "hook" strip of velcro on the back of the hand controller and the" loops" strip on a tripod leg or on the mount where it will be in a conveniently reached spot. Make certain when you attach the velcro that the hand controller will not interfere with the motion of the mount. Operating the Single-Axis Drives Figure 4. For the motor drive system to track properly, the equatorial mount must be polar aligned. axis of the mount so it is parallel to the Earth's axis of rotation (polar axis). Consult the manual that came with your SkyView Pro equatorial mount for details on how to polar align it. The telescope must also be precisely balanced for the motor drive system to properly track the night sky. Consult the manual that came with your mount for details on balancing your telescope on the R. A. Orient the batteries as indicated on the white plastic battery holder. Connect the end of the battery pack's power cord to the DC power input on the hand controller. A cord is permanently connected to the hand controller; connect the modular plug on the end of the cord to the modular jack on the R. A. When observing in the Northern Hemisphere, the N/S switch on the hand controller should be set in the "N" position. For the Southern Hemisphere, it should be in the "S" position. Make sure the thumbwheel on the manual clutch assembly is engaged (i. e. Make certain that the teeth of the motor assembly gear mesh with the teeth of the manual clutch assembly gear. 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. [. . . ] Remember, never use the slow-motion control knobs when the manual clutch is engaged or you could permanently damage the motor. If the bottom right button is pressed, the drive will turn at 2x sidereal rate, which will cause objects viewed in the telescope's eyepiece to move slowly eastward. If the bottom left button is pressed, the drive will stop turning, which will cause objects in the eyepiece to move slowly westward. [. . . ]
