    TPO #47 Violet Color Filter & Case - 1.25"

    Eyepiece filters are an invaluable aid in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue.

    Third Planet Optics filters are made of high quality, solid plane parallel glass with excellent homogeneity. They are anti-reflection coated to prevent glaring and ghosting. All eyepiece filters are threaded to fit most 1.25" eyepieces and offer a full 26mm clear aperture. Comes with a hinged, plastic case to keep your filter safe and clean when not in use.

    #47 Violet (3% transmission): Since the #47 Violet filter strongly rejects red, yellow, and green wavelengths it is useful for the study of Martian polar cap regions and for the observation of occasional phenomena in the upper atmosphere of Venus. This filter also enhances contrast between the rings of Saturn and is useful for detecting faint features on Mercury and for observing bright comets. Use only on telescopes of 8" aperture and larger due to the low light transmission of 3%.
