User manual ORION TELESCOPES & BINOCULARS COLOREYEFILTERSET C

[. . . ] How They Work Planetary surface features and atmospheric phenomena reflect sunlight as contrasting colors which we see as "details" on the "disk" of a planet. An Orion eyepiece filter absorbs a specific color of reflected light: for example, red. Absorbing red will reveal detail of a contrasting color, like green, otherwise disguised by the proximity of the red. [. . . ] Improves contrast and reduces irradiation between features of varying brightness. Also for penetrating the atmospheres of Mars, Jupiter or Saturn. #21 Orange Brings out structure in Jupiter's belts and Saturn's bands. Allows intermediate probing of martian surface features; particularly increases contrast between martian maria and deserts. Especially good for smaller telescopes at higher powers. #47 Violet Reduces yellow and green wavelengths. Increases contrast of upper atmospheric clouds. Also useful in detecting clouds over Martian polar caps. #11 Light Yellow-Green A good filter for enhancing both blue and red features on Jupiter and Saturn, and for showing some detail on Uranus and Neptune with larger scopes. #82A Very Pale Blue A subtle filter good for observing lowcontrast details on Jupiter and Saturn at higher powers, without noticeably reducing brightness. A good filter for stacking with other colors. Enhances images of comet dust tails and heads. Brings out orange and red features of Jupiter and Saturn. Brings out the surface detail on Uranus and Neptune in larger telescopes.

Box 1815, Santa Cruz, CA 95061 IN 013 Rev C 02/03 #23A Light Red 25% Transmission. Sharpens edges of yellow dust clouds on Mars. Highlights the polar areas and blue clouds of Saturn and Jupiter. Corrects the blue coloration of Mylar solar filters, for a more natural appearance. [. . . ] If the stars appear to twinkle a lot, the seeing is probably not ideal. If star images are reasonably stable, the seeing is probably quite good. Care of your color filters To insure long life for your Orion color filters, avoid touching the glass. [. . . ]
