Tele Vue-85
Operating Guide
Thank you for purchasing the Tele Vue-85. We hope it brings great enjoyment to your observing
experience. The wonderfully versatile hand-built 3-1/3" aperture telescope features a diffraction limited,
600mm focal length, f/7 APO doublet objective which delivers razor sharp images sure to please you
for years to come and wherever you observing interests lead you.
WARNING: NEVER try to look at the sun or point the telescope toward or near the sun without
professional solar observing equipment rigidly secured in front of the objective lens. When ob-
serving the sun with the proper filters, use only the Tele Vue "Sol-Searcher" (SSF-1006) for finding
the Sun. Remove any other finding devices such as Starbeam from the telescope. Instant and
permanent eye damage may result from viewing the sun directly, even during a solar eclipse, or when
viewing through thin clouds, or when the sun is near the horizon.
Standard features of the optical tube assembly (O.T.A.) include: sliding dew shield, screw-on cover,
2" rack and pinion focuser, and custom padded carrying bag.
Accessories
The Tele Vue-85 Accessory Package includes a 2" Everbrite diagonal, 2" to 1¼" adapter, Ring Mount,
and DeLite eyepiece.
Mounting - The Tele Vue Ring Mount (available separately or in the package) permits mounting to the Tele
Vue Gibraltar, Panoramic, and Tele-Pod mounts, or heavy duty camera tripods. You will receive the two
¼-20 studs, wing knobs, Allen wrench and complete mount assembly instructions with the mount. Tele Vue
also has adapter plates to allow attachment on specific equatorial mounts (consult your Tele Vue dealer).
Finders - For night use, we recommend the Starbeam reflex sight (SFT-2003) to complement the wide field of the
telescope. The Starbeam attaches to the Ring Mount and can be left in place when the scope is stored in its case.
Use the Qwik-Point (part # QBT-1006) for daytime spotting. It's beam is bright enough for use in
even bright sunlight. However it is too bright for nighttime use.
