IN 538 Rev. A 2/15 Your new Orion Premium 20-Piece 1.25" Color Planetary Filter Set will add versatility and viewing pleasure to your astronomy experience. This set contains 20 color filters and a metal storage case. Please read these instructions thoroughly for proper use and care of the filters. Color Eyepiece Filters Color filters will enhance your visual and photographic observation of the Moon and planets, allowing you to see greater contrast between planetary details of differing colors. Some filters offer additional uses such as enhancing structure detail in galaxies, reducing unwanted false color from achromatic refractors and terrestrial observing at dawn or dusk. How They Work Planetary surface details and atmospheric phenomena reflect sunlight as contrasting colors which we see as details on the disc of a planet. A color eyepiece filter passes (transmits) a specific color of reflected light and blocks (reflects) their complementary colors: for example, red. Passing red will reveal detail of a contrasting color, blue, in this example. This lightening of similar colors and darkening of contrasting colors enhances the detail that you see. Color filters do not actually increase the level of detail, they merely make it easier to see. Figure 1. Comparison illustration of using filters for planetary observation. Attaching the Filters Filters require a 1.25" telescope eyepiece that can accept threaded filters. Any Orion 1.25" eyepiece will work. Simply thread the filter into the eyepiece barrel until it is finger tight. 2 Figure 2. Attaching a filter to a 1.25" eyepiece with filter threads. Stacking Filters You can also "stack" filters by threading another filter into the bottom of the first. Please note to check the transmission curves of the filters that you are stocking to make sure they have some overlap otherwise all visible wavelengths may be blocked or may be too limiting for smaller aperture telescopes. Photography Use the filters photographically by threading them into eyepieces used in teleextenders and universal camera adapters. Some cameras, camera adapters, diagonals and barlow lenses also have the proper threads to accept filters directly. Please note that a UV/IR blocking filter may also need to be used with monochrome cameras to block wavelengths outside of the visible spectrum. Color cameras generally have this filter already attached but monochrome cameras may not. Change Filters Quickly and Safely Without Interrupting Observing or Photography There's also an easy way to change the filter you want for observing or photography. With a filter wheel or filter slider, it is possible to change filters without having to remove your eyepiece or camera thus saving observing time and eliminating the need to fumble around in the dark screwing filters onto accessories. Figure 3. The Orion 1.25" 5-position (manual) filter wheel and the Orion Nautilus 1.25" 7-position (motorized) filter wheel. 3 Figure 4. The Orion 1.25" 8-slot filter slider provides an affordable method to use and exchange filters quickly. Filter Descriptions Numbering/Naming of Filters Each filter is referred to by its color and Wratten number (based upon the historical standard numbering system developed by Kodak/Wratten). Figure 5. Filter showing name and Wratten number (No 15. Yellow). Luminance transmittance % Associated with each filter is a luminance transmittance value (LT %). All filters will reduce the total amount of light reaching the eye based upon this value. For small aperture telescopes best results will be found by using filters that have a higher luminance transmittance value. Larger aperture telescopes are required for low transmission filters such as the W46 Deep Blue (2% LT), the W47 Violet (3% LT) and the W29 Deep Red (6% LT). 4 Types of Filters The following types of filters are included in this set. YELLOWS WB Light Yellow W11 Yellow-Green W12 Yellow W15 Deep Yellow 83% LT 40% LT 74% LT 66% LT ORANGES AND REDS W21 Orange 46% LT W23A Light Red 25% LT W25 Red 14% LT W29 Deep-Red 6% LT MAGENTAS W30 Light Magenta W32 Magenta 27% LT 13% LT BLUES AND BLUE GREENS W38A Blue 17% LT W44A LightBlueGreen 14% LT W46 Deep Blue 2% LT W47 Violet 3% LT 3% LT W56 Light Green 53% LT W57 Medium Green 33% LT W58 Green 24% LT W64 Blue-Green 25% LT LIGHT BALANCING W80A Medium Blue W82A Pale Blue 28% LT 73% LT 5 Figure 6. Visible spectrum graph (400nm to 700nm). Visible spectrum transmission graphs A spectral curve graph in the visible spectrum range (400nm to 700nm) is given for each filter and can be used to examine how the spectral transmittance curve of a particular filter transmits or blocks certain wavelengths.

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 from its housing for cleaning. 26 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.
