Hydrogen Beta, or H-beta filters block out all light except for the 486 nm H-beta wavelength. Browse our collection of visual and astrophotography filters.
Visual H-beta filters significantly improve views of faint nebula such has the Horsehead and California nebulas. Astrophotography H-beta narrowband filters reveal details that the typical Hydrogen Alpha, Sulfer II, and Oxygen III filters do not now.
