To remove fingerprints or smudges from a lens, use photo- graphic-type lens cleaning fluid and lint-free optical lens cleaning tissue. Do not use household cleaners or eyeglass- type cleaning cloth or wipes, as they often contain undesirable additives like silicone, which don’t work well on precision optics. Place a few drops of fluid on the tissue (not directly on the lens), wipe gently, then remove the fluid with a dry tissue or two. Do not “polish” or rub hard when cleaning the lens, as this will scratch it. The tissue may leave fibers on the lens, but this is not a problem; they can be blown off with a blower bulb.

Never disassemble the telescope or eyepieces to clean opti- cal surfaces!
