#47 Violet (3% transmission): Strongly rejects red, yellow, and green wavelengths; useful for the study of Martian polar cap regions and for the observation of occasional phenomena in the upper atmosphere of Venus. Enhances contrast between the rings of Saturn. Use only on telescopes of 8" aperture and larger.
|
#56 Light-Green (24% transmission): Is excellent for the observation of Martian polar ice caps as well as yellow-tinted dust storms on the Martian surface. Increases contrast of the red and blue regions in Jupiter's atmosphere as well as in the clould belts. Also useful for enhancing lunar detail.
|
#58 Green (24% transmission): Use on telescopes 8" aperture and larger to reject blue- and red-toned structures on the surface of Jupiter and thereby increase their contrast relative to lighter parts of the disc. Also use for the enhancement of Saturn’s cloud belts and polar regions. Strongly increases contrast of Mars’ polar ice caps, and increases contrast of atmospheric phenomena on Venus.
|
#80A Blue (30% transmission): A popular filter for the study of Jupiter and Saturn. Enhances contrast of rilles and festoons in Jupiter’s cloud belts, as well as details of the Red Spot. Brings out detail in Saturn’s belts and polar phenomena. Very useful as a contrast-enhancing lunar filter.
|
#82A Light-Blue (73% transmission): useful on the Moon, Mars, Jupiter, and Saturn. This subtle pale blue filter enhances areas of low contrast while avoiding significant reduciton of overall image brightness. A valuable filter to piggyback with other filters.
|
#11 Yellow-Green Used to enhance planetary features on Mars, Jupiter, and Saturn.
|
#12 Yellow (74% transmission): Contrasts strongly with blue-colored features on Jupiter and Saturn, while enhancing red and orange features. Lightens red-orange features on Mars, while reducing or blocking the transmission, and thereby increasing the contrast, of blue-green areas. Useful in increasing the contrast of lunar features in telescopes 6" aperture and larger.
|
#25A Red (14% transmission): strongly blocks the transmission of blue and blue-green wavelengths, resulting in very sharply defined contrast between blue tinted cloud formations on Jupiter and the lighter-toned features of the disk. Also useful for the delineation of the Martian polar ice caps and maria. Because of its relatively low total light transmission the #25A filter should be used on telescopes of 8" or larger.
|
#38A Dark Blue (17% transmission): Is a popular filter for the study of Jupiter's disk, owing to the filter's strong rejection of orange and red wavelengths. It increases contrast between the reddish belt structures and enhances detail of the Red Spot. Also useful for the study of isolated phenomena, such as dust storms, on Mars, as well as the belt structure of Saturn. Increases contrast of subtle cloud markings on Venus.

This adapter permits the use of either Meade flip-mirror system (1.25" #644 or 2 #647") with telescopes using 1.25" focusers. Its use is generally limited to refractors.
|
Transmits light uniformly across the entire visual spectrum. Reduces glare and increases clarity of the moon in scopes 4" plus. Also useful for splitting double stars when one staris significantly brighter than the other.
|
DC power cord lets you power any ETX-PE or LX series scope at home or away from home with your car battery. Includes 25-foot cord.
|
Prime focus camera adapter converts your ETX into a telephoto lens. Threads onto the rear cell of the scope. Requires camera-specific T-mount.
|
LX200 Interface Cable - for all models of LX200s ONLY.
