(ORGB) They bring out subtle details by selectively increasing the contrast among markings of different hues, and by reducing irradiation, the smudging of the boundaries between light and dark regions due primarily to turbulence in the Earth's atmosphere. \u003c\/p\u003e\n\u003c\/center\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003eWith the right color filter, suddenly the indistinct, pale bands of Jupiter resolve into loops and festoons. Delicate markings appear on Saturn's globe, and the Cassini and crepe divisions darken and solidify. Mars' polar caps stand out like tiny pearls, and vague lunar rilles acquire greater depth and contrast.
