The Astromania 1.25" Narrowband H-Alpha Night Sky Filter is engineered to block urban light pollution by filtering out artificial mercury and sodium vapor emissions, while allowing over 90% transmittance of wavelengths above 650nm. Designed with hardened multicoatings and precise narrowband cutoff at 640nm, it delivers high-contrast, sharp images of H-II regions and emission nebulae. Compatible with all standard 1.25" digital imagers, this filter transforms urban night sky photography into a professional-grade experience.
