The H-alpha filter transmits light at a wavelength of 656 nm, making it an excellent choice for narrowband H-alpha astrophotography. It delivers high-contrast images and reveals rich nebular details, even in areas with strong light pollution. These 50 mm filters are compatible with all 50 mm filter wheels from ZWO, QHY, QSI, Starlight Xpress, SBIG, Moravian, and Atik. The filter design includes a protective ring and blackened edges to prevent stray light, provide mechanical protection, and make handling easier. 

H-alpha Filter: This filter is designed for photographing hydrogen nebulae both in areas with artificial light pollution and at dark-sky locations. It significantly enhances the contrast between H-alpha emitting objects and the sky background. With a narrow half-width of 12 nm and high transmission close to 100% in the H-alpha line, it provides much greater contrast than broadband filters. The 12 nm half-width is optimized for typical CCD and CMOS sensors.

H-alpha Filter: This filter is designed for photographing hydrogen nebulae, whether you are in areas with artificial light pollution or under dark skies. It significantly boosts the contrast between H-alpha emitting objects and the sky background. With its narrow 12 nm half-width and nearly 100% transmission at the H-alpha line, this filter provides a much greater contrast increase than broadband filters. The 12 nm half-width is ideally suited for typical CCD and CMOS sensors.

H-alpha Filter: This filter is designed for photographing hydrogen nebulae, whether you are in areas with artificial light pollution or under dark skies. It significantly enhances the contrast between H-alpha emitting objects and the background sky. Thanks to its narrow 12 nm half-width and almost 100% transmission at the H-alpha line, this filter provides much greater contrast than broadband filters. The 12 nm half-width is specifically optimized for use with typical CCD and CMOS sensors.
