Colour eyepiece filters are essential for observing the moon and planets. They effectively reduce glare and light scattering, improve contrast through selective filtration, and enhance definition and resolution. Bintel's filters are constructed with top-notch, uniform glass and are coated to minimize reflections and ghosting. They are threaded to fit 1.25" eyepieces and provide a generous 26mm clear aperture. #12 Yellow Filter The #12 yellow filter enhances Jupiter’s cloud bands, particularly the lighter zones and the Great Red Spot, improves Mars' surface details, such as polar ice caps and dust storms, and sharpens contrast on the Moon, highlighting the maria and highlands. #15A Dark Yellow Filter The #15A dark yellow filter improves contrast on Jupiter's cloud belts, especially in the darker equatorial regions and the Great Red Spot, reveals surface features on Mars such as ridges and valleys, and enhances the details of lunar craters and shadows along the terminator. #21 Orange Filter The #21 orange filter helps define the atmospheric cloud structures on Jupiter and Saturn, enhancing features like the Great Red Spot and Saturn’s cloud bands, sharpens the visibility of Mars’ dust storms and polar ice caps, and brings out lunar surface details, particularly in shadowed areas. #23A Light Red Filter The #23A light red filter enhances the contrast of surface features on Mars, such as ice caps, dust storms, and topography, improves the visibility of Jupiter’s cloud belts and storms like the Great Red Spot, and highlights the Moon’s surface features along the terminator, including craters and maria. #29 Dark Red Filter The #29 dark red filter significantly enhances the contrast of Mars’ surface features like its ice caps, dust storms, and valleys, brings out darker regions and bands in Jupiter's atmosphere, and improves lunar contrast, especially in low-light areas and the terminator. #38A Dark Blue Filter The #38A dark blue filter enhances Jupiter’s cloud details, especially the lighter and darker zones and the Great Red Spot, improves the visibility of cloud layers on Saturn, and helps to bring out surface features such as the polar ice caps as well as dust storms on Mars by enhancing atmospheric contrasts. #47 Violet Filter The #47 violet filter brings out atmospheric features on Jupiter, such as cloud bands and storm systems, enhances the visibility of cloud layers on Saturn, and improves the contrast of Venus' upper atmosphere, revealing subtle cloud structures and atmospheric patterns. #58A Dark Green Filter The #58A dark green filter increases contrast in Jupiter’s cloud bands and atmospheric details, such as the Great Red Spot and polar regions, enhances Saturn’s ring details and cloud structures, improves the visibility of Mars’ surface features like polar ice caps and dust storms, and sharpens Venus’ cloud patterns.
