TPO #58A Green Color Filter & Case - 2"

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. This eyepiece filter is threaded to fit most 2" eyepieces and comes with a hinged, plastic case to keep it safe and clean when not in use.

#58A Green (24% transmission): Use the #58 Green Filter on telescopes 8" aperture and larger to reject blue- and red-toned structures on the surface of Jupiter and thereby increase their contrast relative to lighter parts of the disc. The TPO 58 Green Filter can also be used to enhance Saturn cloud belts and polar regions. This filter strongly increases the contrast of Mars; polar ice caps, and increases contrast of atmospheric phenomena on Venus.
