Cleaning the Optics
A small amount of dust or a few specks on the glass objec-
tive (main) lens will not affect the performance of the
telescope. If dust builds up, however, simply blow it off with a
blower bulb, or lightly brush it off with a soft camel-hair brush.
Avoid touching optical surfaces with your fingers, as skin oil
may etch optical coatings.
To remove fingerprints or smudges from a lens, use photo-
graphic-type lens cleaning fluid and lint-free optical lens
cleaning tissue. Don’t 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 optical surfaces!
If you follow these simple instructions, your Orion Observer
60 AZ Refractor will provide you with years of enjoyable
exploration.
