Product Details

Filter Kepler n° 21 orange 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 an indispensable filter for planetary photography, as it reduces (and even blocks) blue and green wavelengths; it is used in telescopes of 80 mm or more in the observation of Jupiter and Saturn to increase details and scallops in polar zones and belts; it clarifies the boundaries between different areas of the Martian surface, enhancing the contrast in blue and green areas of Mars; it contrasts Venus and Mercury when observed in daylight, it increases the contrast of certain details on the Moon.
