The Astromania 1.25" H-Alpha Night Sky Filter is a long-pass filter designed to enhance astronomical observations. It has a 50% transition from blocking to passing at about 640nm, with 80% or above transmittance at wavelengths longer than 650nm. This filter is ideal for extreme anti light-pollution applications and for contrast-enhancement of emission nebulae and other astronomical objects bright in the infrared. It threads into the nose-piece of industry-standard 1.25" digital imagers, improving image quality even under urban skies.Features:- Incredible light pollution cut-off characteristics- Enables high-contrast deep sky images of H-II regions- Unmatched optical quality and high-efficiency hardened multicoatings- Results in sharpest and highest contrast images possible- Enhances contrast between object and sky for quality imaging
