Adds contrast to blues and enhances reds and
yellows on Jupiter and Saturn, increases contrast
on Mars and the moon (in scopes 6" plus).
#23A Light Red (25% transmission):
Enhances detail in polar regions of Jupiter,
Saturn and Mars (in scopes 6" plus). Also
increases contrast between Mercury and
evening sky.
#58 Green (24% transmission):
On telescopes 8" plus, this green increases
belt structure on Jupiter and Saturn’s surface
and in Saturns rings. Also enhances Mars
ice caps.
#80A Blue (30% transmission): A
popular filter for enhancing spiral features in
Jupiter’s cloud belt (including the Red Spot),
and adding contrast to Saturn and the moon.

S e t N u m b e r Two :
#11 Yellow-Green (78% transmission):
Contrasts with red and blue features on
Jupiter, and Saturn. Darkens the maria
on Mars. Clarifies the Cassini division in
Saturns rings.
#25A Red (14% transmission): Dark red
blocks blue and blue-green for sharp contrast
in Jupiter’s cloud belts. Helps dene polar caps
and maria on Mars. For telescopes 8" plus.
#47 Violet (3% transmission):
Strongly rejects red, yellow and green. For
study of Martian polar caps, the atmosphere
of Venus, Saturn’s rings. For telescopes 8" plus.
#82A Light Blue (73% transmission):
Useful on the moon, Mars, Jupiter, and
Saturn. Light blue adds contrast without
robbing image brightness. A valuable filter
for stacking.

red and orange features of Jupiter, Uranus
and Neptune.
#21 Orange (46% transmission): Blocks
blue-green wave lengths to enhance detail
in polar regions of Jupiter and Saturn. Also
sharpens edge detail of maria on Mars.
#38A Dark Blue (17% transmission):
Popular for study of Jupiter. Strongly rejects
orange and red for greater cloud belt and Red
Spot contrast. Also for Mars, Saturn and Venus.
#56 Light Green (53% transmission):
Excellent for Marspolar ice caps and
yellow-tinted dust storms. Also for increasing
red and blue features on Jupiter and lunar
contrast.

P o l a r i z i n g F i lt e r ( a va i l a bl e s ep a ra te l y ) :
ND 96 Moon Filter (0.9 density; 13% transmission): 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 star
is significantly brighter than the other.
Variable Polarizing Filter (1.25"): The adjustable way to reduce glare
when observing the moon. Includes two polarizer filters mounted in a special
cell that accepts 1.25" eyepieces. Allows you to vary light transmission from 5%
to 25% so you can adjust the filter’s brightness to match the brightness of the
moon during different phases. Variable brightness is also useful when you change
magnification or observe through telescopes of various apertures.

An economical alternative to Series 4000 filters, this set includes widely-
used red, yellow, blue and neutral density-filters that adapt to most viewing
