This high quality colour filter set contains 3 colour filters and a neutral density filter for planetary and lunar observations. It comes in a foam lined plastic screw top storage case.

Size: 1.25"
Material: optical quality glass
Filters included:
#8 - yellow (greenish yellow)
#47 - dark blue
#82A - light blue
ND96-0.9 - neutral density (grey) filter with 13% transmission level

DARK YELLOW: from 120mm. Increases contrast of surface features of the Moon, clouds of Mars and reinforces atmospheric structures of Jupiter (i.e. Great Red Spot).
YELLOW: same as dark yellow but from 80mm aperture. Very good for observing the Moon (reduces blue chromatic aberration of achromats, thus increases contrast)

GREEN: from 60mm. An important universal contrast filter. Strong enhancement of surface features of the Moon. Very good for low magnifications. Enhances reddish structures in the Great Red Spot on Jupiter. Also good for Mars and Saturn.
LIGHT BLUE: from 50mm. An important universal colour filter for small telescopes. Brings contrast enhancement to many solar system objects.
BLUE: from 70mm. General contrast strengthening for the Moon - away from the terminator. Very good for increasing contrast in the bands of Jupiter and Saturn. Good for comet hunting: enhances the contrast of the tail.
DARK BLUE: from 100mm, but
ideal from 150mm aperture. Same as blue.
