On Jupiter and Saturne, contrast is enhanced on the bluish ammonia cloud belts.#21 Orange - The orange filter blocks blue and green wavelengths, thus enhancing details in Saturne's and Jupiter's cloud belts. On Mars, it sharpens boundaries between orange and greenish areas. #23A Red - The red filter blocks blue and green light nearly in total, which means you get a very strong contrast, for instance, between bluish toned structures and the brighter details on Jupiter's and Saturn's clouded surface. However, this filter is mainly used to observe Martian polar caps.#82A Light blue - The light blue filter is suitable for Moon, Mars, Jupiter and Saturne observation. It improves contrast on faint areas without affecting the planet's brightness, which is why this filter is often used in combination with others.#56 Light green - The light green filter is ideal for observing the ice caps on Mars and the yellowish sand storms on the Martian surface. It also improves the contrast of reddish and bluish structures in Jupiter's atmosphere.Moon&Skyglow - The violet filter totally blocks red, yellow and green light, which is useful when observing the polar regions on Mars. With larger telescopes (>12"), it also allows to distinguish some structures in Venus' atmosphere.
