The Bushnell Voyager telescopes use refractive optics.

Bushnell Voyager telescopes are refractive telescopes that must be assembled for use. Components include the main telescope body, aluminum tripod, eyepiece, diagonal mirror, finderscope with bracket, equatorial mount with counterweight, accessory tray and axis locking tool. The assembled telescope is then adjusted according to the latitude at which it is used.

Assembly

    Set up the tripod. Loosen the leg lock screws and extend the tripod legs one at a time. Tighten the leg lock screw to lock the extended leg. Spread the tripod legs until the accessory tray supports are fully extended. Attach the accessory tray to the tray supports and secure with the knob.

    Attach the finderscope. Loosen the finderscope adjustment screws and place the finderscope inside the finderscope bracket. Fix in place by gently finger-tightening the adjustment screws.

    Attach the telescope cradle around the main tube and attach the tube to the equatorial mount on the tripod using the cradle lock screws.

    Attach the fine adjustment cables to the silver posts underneath the right ascension axis and the declination axis. Fix in place by finger-tightening the set screws on the end of each cable.

    Thread the counterweight shaft into the hole in the bottom of the declination column and slide the counterweight onto the shaft. Balance the telescope by moving the counterweight to the appropriate position on the shaft and secure it by tightening its thumb screw.

    Set the eyepiece into the diagonal mirror and place the diagonal mirror into the focusing draw tube on the end of the telescope.

    Use the levers on the equatorial mount to point the telescope anywhere you like. Use the finderscope to locate an object. Adjust the finderscope with the mounting screws so the view is centered with the view through the main telescope.

    Things You'll Need

    • Bushnell Voyage telescope
    • Local latitude
    • Compass

    Tips

    • You can adjust the equatorial mount according to your latitude so you can manually track objects in the sky after you have located them.
