Filtre for Nebula H-Beta 1,25’’ - Explore Scientific

H-Beta 1,25" nebula filter from Explore Scientific is ideal for enhancing the observation of emission nebulae dominated by hydrogen. This filter blocks almost all artificial light, only allowing the hydrogen emission lines at 486 nm to pass through, which reveals celestial objects that are invisible without a filter, such as the Horsehead Nebula. With improved contrast, even under slightly illuminated skies, this filter is an essential tool for amateur astronomers passionate about deep-sky exploration.
