H-Beta Nebula Filter 1.25'' - Explore Scientific

The Explore Scientific H-Beta 1.25" nebula filter is ideal for enhancing the observation of hydrogen-dominated emission nebulae. This filter blocks almost all artificial light, allowing only the hydrogen emission lines at 486 nm to pass through, revealing celestial objects that are invisible without a filter, such as the Horsehead Nebula. With improved contrast, even under slightly light-polluted skies, this filter is an essential tool for amateur astronomers passionate about exploring deep sky.
