Mounting points are provided on top of the focuser body and draw tube for easy installation of the
Digital Micrometer Kits (part#s RMK-2002 or RMF-2003). These kits allow imagers to index focus posi-
tion to within 0.0001”, providing a very convenient way of finding best focus, returning to it, or checking
that it hasn’t changed. The dual speed focuser with its 10:1 focus reduction provides extraordinarily fine
focus adjustment for critical focusing. The Focusmate Driver (part# FDF-2004) adds hands free motorized
focusing. For installation, setup and use of the Digital Micrometer Kit and Focusmate Driver, see the instruc-
tions included with each.
1.5 Caring for the
Tele Vue
-85
Tele Vue-
85 requires no special care. Treat it as you would any fine camera lens. Use the lens cap
when the telescope is being stored or not in use. The captive dew shield provides protection from glare,
helps protect the lens from dust or spray blown in by the wind and minimizes dew formation on the lens.
If dew forms on the lens during cold weather, it is best to use an electric hair dryer (on the lowest
setting) to gently warm it away. A few specks of dust will have no effect on the quality of the image, and
may be gently blown off with a squeeze bulb. Do not use compressed air cans to blow dust off any opti-
cal surfaces.
Fingerprints, however should be cleaned off. Though the anti-reflection coatings are durable, they
are easily scratched. The simplest cleaning method is to moisten a very soft, lint-free tissue, cloth, “Q-Tip”
or surgical cotton with a lens or glass cleaner and gently whisk away the stain. Do not apply any solutions
directly to the glass surfaces. After every cleaning stroke, use a fresh applicator. The fewer strokes the
better! Any residual “film” will not affect visual performance.
Collimation of your
Tele Vue-
85 has been locked at the factory. With reasonable care it will
remain aligned. However, rough handling can cause misalignment. WARNING: Do not loosen the but-
ton head screws in the front lens cell as this will cause misalignment. If necessary, contact Tele Vue for
re-collimation.
Our 90° and 60° star diagonals employ a first-surface mirror. Like all first-surface mirrors, they should
be cleaned only when absolutely necessary. First blow loose dust away with a squeeze bulb. CAUTION:
Do not clean mirror with water or water based cleaners such as Windex or any other commercial lens
cleaners; this is not a lens. All contain too much water and will leave a residue. Moisten a “Q-Tip” with
methanol or Isopropyl alcohol, reagent grade. Clean gently using only the weight of the cotton swab. Use
very light pressure and never rub. Slight residual stains or dust spots will have no visible effects in observing.
The tube and other parts are powder-coated for durability and can be polished with any non-abrasive
car wax. Black anodized surfaces can be cleaned with Windex.
