Product Details
TPO filters are made of high quality, solid plane parallel glass with excellent homogeneity. They are anti-reflection coated to prevent glaring and ghosting. This eyepiece filter is threaded to fit most 1.25" eyepieces and comes with a hinged, plastic case to keep your filter safe and clean when not in use.
#25 Red (14% transmission): The #25 filter strongly blocks the transmission of blue and blue-green wavelengths, resulting in very sharply defined contrast between, for example, blue-tinted cloud formations on Jupiter and the lighter-toned features of the disc. Also useful for the delineation of the Mars polar ice caps and maria. Because of its relatively low total light transmission, the #25 filter should be employed on telescopes of 8" aperture and larger.
