Filter Kepler n° 11 yellow-green for 1.25" eyepieces

Color filters are used to enhance contrast when observing lunar and planetary surfaces. Each color helps to observe specific details (Martian seas or polar caps, clouds on the surface of Jupiter or Venus, etc.). They are screwed to the barrel of the 31.75 mm diameter eyepieces and the specific colorant is embedded inside the glass itself. The reference of each filter is given by its color according to the Wratten catalog.

Use: increases contrast when observing seas and poles of Mars, red-orange and blue details on Jupiter and Saturn, increases Cassini division on Saturn's rings, improves resolution of Uranus and Neptune with 10" or larger aperture telescopes, enhances cometary jets. Reduces false purple color in achromatic refractors with a Fraunhofer doublet mounted on the objective.
