Neewer

NEEWER 1.25' Telescope Eyepiece Filter Set (10 Pack), Including Planetary, Variable, UHC, Lunar & Starglow Filters for Moon Observation

【5 Planetary Color Filters】 5 planetary filters in red, orange, yellow, green, and blue reveal details, emphasize features, and sharpen the contrast of Mercury, Mars, Venus, Jupiter, Saturn, Moon, and other celestial objects
【Variable Polarizing Filters】 Two rotating variable polarizing filters change light transmission from 40% to 1%. They reduce reflection and glare, darken the sky background, and boost visual contrasts to make planets and stars stand out. No chromatic aberration.
【Combine to Get a Variable ND Filter】Stacking two polarizing filters together will give you a variable ND2-2000 ND filter, which can be used freely on the telescope without affecting the focal length at all, helping you to capture more brilliant star rivers. Note: The thinner polarizing filter needs to be mounted underneath the ringed polarizing filter.
【UHC Filter & Lunar Filters】 UHC (Ultra High Contrast) filter minimizes manmade light pollution like streetlights for sharp nebular viewing in urban and rural areas. The 13% transmission lunar filter allows only 13% light transmission to boost contrast and emphasize lunar features like craters, mountains, and valleys. The lunar & starglow filter can block unwanted 589nm wavelengths of light, and improve observation of the night sky in urban and rural areas.
【10PCS Telescope Filter Set】 This telescope eyepiece filter set includes 5 x Planetary Color Filter, 2 x Variable Polarizing Filter, 1 x UHC Filter, 1 x Lunar & Starglow Filter, and 1 x 13% Transmission Lunar Filter to enhance astronomical observation & photography
