Chroma 3nm H-Alpha Filter Optimized for f 2.8-f 3.6

H-alpha filters are essential for imaging nebulae and other objects which are rich in ionized hydrogen. At 656.3nm, a narrow-band emission filter is required to separate H-alpha from the SII doublet (671.6nm and 673.1nm). Chroma’s f 3.0 filters are designed to minimize spectral shift and hold their shape better in an f 3.0 beam.
