The Orion 2" LRGB Imaging Filter Set includes luminance
(L), red (R), green (G), and blue (B) lters which allow you to
create stunning composite color images of night-sky objects
when used with a monochrome imaging system. Each lter
provides a clear aperture of 43.2mm which is suitable for
larger format CCD cameras.
Celestial objects such as nebulae and galaxies look very dif-
ferent when observed or imaged in specic colors of light.
Different processes and structures within celestial objects emit
light of varying color. Certain features and details will seem to
“pop out” of objects when viewed or imaged with wavelength-
specic lters. The Orion LRGB lter set allows you to isolate
red, green, and blue light for imaging purposes. Additionally,
the full-spectrum luminance lter adds superb image resolu-
tion to the process.
All Orion LRGB lters have been made to cut out infrared (or
IR) wavelength light which can detract from image quality.
CCD cameras are also sensitive to unwanted IR light which
can easily contaminate the resultant image combination. Each
Orion LRGB lter blocks all infrared light with a wavelength
above 690nm which makes creating sharp images even easier.
Orion LRGB lters are dichroic and utilize microscopic mul-
tiple-layer coatings, which allow them to reect unwanted
wavelength light and allow specic wavelength light to pass
through. Due to their dichroic design, the LRGB lters have
a reective appearance. Dichroic lters last much longer than
conventional lters as the color is intrinsic in the construction
of the hard microscopic layers and cannot fade out over the
lifetime of the lter.
Using the LRGB Filter Set
For most convenient use of the LRGB lter set we recommend
the Orion 2” Multiple Filter Wheel.The lter wheel allows you to
quickly change the lter in the light path without the sometimes
frustrating process of removing the imaging system every time
a different lter is needed.
Due to their parfocal design, you will generally not need to
refocus your telescope when switching between lters. To
use the LRGB lter set with the lter wheel simply thread all
four lters into the lter wheel tray as described in the wheel
instructions. You can now switch between LRGB lters by
rotating the knurled wheel.
As most imaging systems are not equally sensitive to all wave-
lengths of light, exposure times may vary for each of the LRGB
lters. This will depend on your imaging camera, telescope,
and celestial target object. Contact Orion Customer Service /
Sales at OrionTelescopes.eu for details.
Care and Storage
When not in use, your lters should be kept in their original
foam-lined case. Given proper care and storage, the lters
should last a lifetime. Should a 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 clean-
ing uid specically designed for multi-coated optics can be
used to clean the glass surfaces of the lter. Never use regular
glass cleaner or cleaning uid designed for eyeglasses.

One-Year Limited Warranty
This Orion product is warranted against defects in materials or workmanship for a period of one year from
the date of purchase. This warranty is for the benet of the original retail purchaser only. During this war-
ranty period Orion Telescopes & Binoculars will repair or replace, at Orion’s option, any warranted instru-
ment that proves to be defective, provided it is returned postage paid. Proof of purchase (such as a copy
of the original receipt) is required. This warranty is only valid in the country of purchase.
This warranty does not apply if, in Orion’s judgment, the instrument has been abused, mishandled, or
modied, nor does it apply to normal wear and tear. This warranty gives you specic legal rights. It is not
intended to remove or restrict your other legal rights under applicable local consumer law; your state or
national statutory consumer rights governing the sale of consumer goods remain fully applicable.
For further warranty information, please visit www.OrionTelescopes.com/warranty.
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 the
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 nger-
prints and smudges may be removed
using this method. Use caution: rub-
bing too hard may scratch the lter
glass. Do not remove the lter glass
form its housing for cleaning.
