Product Details

Filter Kepler no. 25 red 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 is a filter suitable for large telescopes, with diameters of 8" or larger, that blocks blue and blue-green wavelengths offering increased contrast between blue cloud formations on Jupiter; enhances contrast in blue and green areas of Mars and is also used for observation of the Martian polar caps; increases contrast between the twilight sky and Mercury by darkening the sky background; in very large telescopes (10 " or larger) it is used to bring out details in the atmosphere of Uranus.
