Chroma Filters H-Alpha 5nm 2" (66078)

The H-alpha narrowband filter is designed for astrophotography, allowing light at a wavelength of 656nm to pass through while blocking all other wavelengths. It is the ideal choice for high-contrast imaging, revealing detailed structures in emission nebulae and hydrogen nebulae. This filter works effectively even in areas with strong light pollution, enabling astrophotographers to capture breathtaking deep-sky images directly from urban environments.
