Filter Kepler n° 23A pale 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 an indispensable filter for planetary photography, as it reduces (and even blocks) blue and green wavelengths; it is similar to Wratten #21 but for Ø telescopes
