Filter Kepler No. 47 violet 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 absorbs green, red and yellow wavelengths, so it is only suitable for telescopes with apertures of 200 mm or larger. It is used to enhance the red, yellow and green areas of the polar areas of Mars, achieving excellent enhancement of the ice caps; it contrasts Venus against the twilight sky and diminishes its extreme brightness and scintillation and highlights atmospheric details such as occasional phenomena in the Venusian polar areas. Increases the contrast between the rings and Saturn. Suitable for visual observation and astrophotography.
