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

Tele Vue at (845) 469-4551 from 9:30 am to 5:00 pm EST.
