one-Year limited Warranty
This Orion Observer 60mm Ultra Altazimuth Refractor is warranted against defects in materials or
workmanship for a period of one year from the date of purchase. This warranty is for the benefit of
the original retail purchaser only. During this warranty period Orion Telescopes & Binoculars will
repair or replace, at Orion’s option, any warranted instrument that proves to be defective, provided
it is returned postage paid to: Orion Warranty Repair, 89 Hangar Way, Watsonville, CA 95076. If the
product is not registered, proof of purchase (such as a copy of the original invoice) is required.
This warranty does not apply if, in Orion’s judgment, the instrument has been abused, mishandled,
or modified, nor does it apply to normal wear and tear. This warranty gives you specific legal rights,
and you may also have other rights, which vary from state to state. For further warranty service
information, contact: Customer Service Department, Orion Telescopes & Binoculars, P. O. Box 1815,

Your Observer 60mm Ultra requires very little mechanical
maintenance. The optical tube is aluminum and has a smooth
painted finish that is fairly scratch-resistant. If a scratch does
appear on the tube, it will not harm the telescope. If you wish,
you may apply some auto touch-up paint to the scratch.
Smudges on the tube can be wiped off with a soft cloth and a
household cleaner such as Windex or Formula 409.
cleaning the optics
A small amount of dust or a few specks on the glass objective
(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 touch-
ing 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 opti-
cal surfaces!
If you follow these simple instructions, your Orion Observer
60mm Ultra Altazimuth Refractor will provide you with years
of enjoyable exploration.
