Filter Kepler n° 58A dark 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: This filter strongly blocks red and blue, thus increasing the contrast in the light bands of Jupiter. It also improves the observation of Saturn's cloud bands and polar areas. It strongly enhances the contrast of the poles of Mars and the atmospheric phenomena of Venus. Due to the strong blocking, it should only be used in telescopes with apertures equal to or larger than 200 mm.
