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.
Your star diagonal employs a first-surface mirror. Like all first-surface mirrors, it 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 pure acetone or
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 is powder-coated for durability and can be polished with any non-abrasive car wax. Black
anodized surfaces can be cleaned with Windex.
If you have any questions about the care, operation or performance of your Tele Vue-85, please call
