Chroma Technology 3nm/5nm H-beta Filters (27004/27005)

Chroma Technology 3nm/5nm H-beta Filters (27004/27005)H beta filters are also useful for imaging nebulae and objects rich in ionized hydrogen. At 486. 1nm, a narrow band filter is required to separate H beta from nearby blue and green spectral lines. Although weaker than the H alpha line, this is often used for visual detection as the longer red wavelengths of H alpha are difficult to detect by eye.
