The Baader 50.4 mm F2 High-speed H-alpha Filter is designed for very fast astrograph optics particularly Hyperstar and RASA. Due to strong CWL shift, the H-alpha filter causes heavy loss of transmission. In severe cases the CWL do not shift out of the FWHM so this filter have a CWL-preshift to match F2 to F3 perfectly.

Despite of typical line broadening, they are capable of delivering maximum contrasted images. This filter shows a considerable improvement when using them between F1.8 and F3.5. Along with 3 mm thickness, the H-alpha filter is planeoptically polished and di-electrically coated.
