Filter Kepler No. 29 dark 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: Highly recommended for CCD photography in IR (infrared), as it blocks wavelengths below 600nm, achieving excellent contrast on Jupiter, Saturn, Uranus and Neptune; with large telescopes (diameters greater than 8"), it improves the contrast of the poles of Mars.
