LRGB Imaging Filter Set, 2"

#5567

The Orion 2" LRGB Imaging Filter Set includes luminance
(L), red (R), green (G), and blue (B) filters which allow you to
create stunning composite color images of night-sky objects
when used with a monochrome imaging system. Each filter
provides a clear aperture of 43.2mm which is suitable for
larger format CCD cameras.

Celestial objects such as nebulae and galaxies look very dif­ferent when observed or imaged in specific 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 wavelength­specific filters. The Orion LRGB filter set allows you to isolate
red, green, and blue light for imaging purposes. Additionally,
the full-spectrum luminance filter adds superb image resolu­tion to the process.

All Orion LRGB filters 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 filter blocks all infrared light with a wavelength
above 690nm which makes creating sharp images even
easier.

Orion LRGB filters are dichroic and utilize microscopic
multiple-layer coatings, which allow them to reflect unwanted
wavelength light and allow specific wavelength light to pass
through. Due to their dichroic design, the LRGB filters have
a reflective appearance. Dichroic filters last much longer than
conventional filters as the color is intrinsic in the construction
of the hard microscopic layers and cannot fade out over the
lifetime of the filter.

Using the LRGB Filter Set

For most convenient use of the LRGB filter set we recommend
the Orion 2” Multiple Filter Wheel. The filter wheel allows you
to quickly change the filter in the light path without the some­times frustrating process of removing the imaging system
every time a different filter is needed.

Due to their parfocal design, you will generally not need to
refocus your telescope when switching between filters. To
use the LRGB filter set with the filter wheel simply thread all
four filters into the filter wheel tray as described in the wheel
instructions. You can now switch between LRGB filters by
rotating the knurled wheel.

As most imaging systems are not equally sensitive to all wave­lengths of light, exposure times may vary for each of the LRGB
filters. This will depend on your imaging camera, telescope,
and celestial target object. Contact Orion Customer Service /
Sales at 800-676-1343 for details.

Care and Storage

When not in use, your filters should be kept in their original
foam-lined case. Given proper care and storage, the filters
should last a lifetime. Should a filter need cleaning for any
reason, use the following directions to clean the filter without
damaging it.

Any quality optical lens cleaning tissue and optical lens clean­ing fluid specifically designed for multi-coated optics can be
used to clean the glass surfaces of the filter. Never use regular
glass cleaner or cleaning fluid designed for eyeglasses.

Before cleaning with fluid and tissue,
blow any loose particles off the sur­face with a blower bulb or compressed
air. Then apply some cleaning fluid to
the tissue, never directly on the optics.
Wipe the lens gently in a circular
motion then remove any excess fluid
with a fresh lens tissue. Oily finger­prints and smudges may be removed
using this method. Use caution: rub­bing too hard may scratch the filter
glass. Do not remove the filter glass
form its housing for cleaning.

One-Year Limited Warranty

This LRGB Imaging Filter Set is warranted against defects in materials or work man ship 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
