The Orion variable polarizing lter reduces the amount of light entering
your eyepiece from your telescope.You can dim the view when observ-
ing a bright object, such as the Moon or a planet. The variable polar-
izing lter will not change the color of the object being viewed, and will
prevent eye fatigue and loss of night vision.
Assembly
The 1.25" variable polarizing lter comes in two halves; the upper half,
with the knurled ring, and the lower half, with the logo. To assemble,
simply thread the lower half into the upper half until it is nger tight
(Figure 1). The top ring of the lter should now turn freely without
unthreading the two halves. You can look through the lter at a source
of light while turning the ring to see the effect it has in reducing light. To
separate the two halves, hold the lter by the knurled ring on the upper
half and unthread the lower half. The 2" variable polarizing lter comes
already assembled in its case.
To use the lter in a telescope, simply thread the assembled lter into
any telescope eyepiece that accepts 1.25"(for #5560) or 2" (for #5562)
lter threads, such as any Orion eyepiece. Thread the lter into the
eyepiece until it is nger tight.
You may also “stack” other lters by threading them into the bottom of
the variable polarizer.

Using the Polarizing Filter
Insert the eyepiece with the lter attached into the telescope and
focus the image. If the image is too bright or too dark, then remove
the eyepiece and rotate the ring on the lter a small amount. Don’t
turn it too much, as the lter goes from its maximum light transmis-
sion to its minimum transmission in just a 1/4 turn of the ring.
Re-insert the eyepiece and check the image again. Repeat this
process until you have the desired level of brightness.
Terrestrial Viewing
The variable polarizing lter can be used during the day to reduce
sunlight glare from lakes, oceans, or window glass. Simply
unthread the lower half from the upper half of the lter and thread
either half into a eyepiece. Once the eyepiece is returned to the
telescope and focused, rotate it in the focuser to reduce glare. You
will not be able to reduce overall brightness by using only one lter,
but you will be surprised at how much control you have over
reected light.
Cleaning & Maintenance
When not in use, the variable polarizing lter should be kept in its
original padded case. Given proper care and storage, the lter
should last a lifetime. Should the lter need cleaning for any reason,
use the following directions to clean the lter without damaging it.
Any quality optical lens cleaning tissue and optical lens cleaning
uid specically designed for multi-coated optics can be used to
clean the glass surfaces of your lter. Never use regular glass
cleaner or cleaning uid designed for eyeglasses.
Before cleaning with uid and tissue, blow any loose particles off
the surface with a blower bulb or compressed air. Then apply some
cleaning uid to a tissue, never directly on the optics. Wipe the lens
gently in a circular motion, then remove any excess uid with a fresh
lens tissue. Oily ngerprints and smudges may be removed using
this method. Use caution; rubbing too hard may scratch the glass.
