Filter Kepler no. 8 light yellow 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: With apertures of 6" or larger, increases contrast when observing seas of Mars and the Moon, dust tails of comets, red-orange belts on Jupiter and Saturn; improves resolution of Uranus and Neptune with telescopes of aperture 10" or larger; decreases false purple color in achromatic refractors that mount a Fraunhofer type doublet on the objective.
