Tele Vue 76 - Manual (Page 5)

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 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.
If you have any questions about the care, operation or performance of your Tele Vue-76, please call
Tele Vue at (845) 469-4551 from 9:30 am to 5:00 pm EST.
