The 1.25" Bandmate Planetary Filter from Tele Vue is an eyepiece filter specifically engineered to enhance contrast when viewing the gas giants Jupiter and Saturn. This optical accessory combines BK-7 optical glass and a machined aluminum cell to create a reliable filter optimized for planetary observation. An ion beam-deposited protective lens coating helps the filter resist changes in ambient temperature and humidity. The color balanced dielectric filter polarizes incoming light, blocking unwanted wavelengths and enhancing the contrast of transmitted colors.
