🌠 Capture the cosmos like never before — even from your city rooftop!
The Astromania 1.25" Narrowband H-Alpha Night Sky Filter is a premium optical accessory designed to dramatically reduce light pollution by blocking artificial mercury and sodium vapor lights. With over 90% transmittance above 650nm and advanced multi-coatings, it enhances contrast and sharpness for deep sky imaging of H-II regions and emission nebulae. Compatible with all standard 1.25" digital imagers, this filter empowers urban astronomers to capture stunning, high-contrast celestial photos despite city light interference.
