#23A Light Red- The red filters are made from renowned Schott and Hoya optical glass and allow for maximum contrast on viewing planetary and lunar detail; #12 Yellow - The yellow filter improves contrast on Moon craters; on Mars; channels and polar caps become more apparent
#80A Blue - The 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
#47 Violet - The violet filter totally blocks red; yellow and green light; which is useful when observing the polar regions on Mars; with larger telescopes ">12inch"; it also allows to distinguish some structures in Venus' atmosphere
Variable Grey Polarizing Filter - The variable polarizing filter allows for selective adjustment of brightness; which is useful for terrestrial observation; light transmission of polarizing filters is between 1% and 40%
