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- specific 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.

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.
