Chroma Filters H-Alpha 1,25", 5nm (66074)

The H-alpha narrowband filter is specifically designed for astrophotography, allowing light at a wavelength of 656nm to pass through. It is the perfect choice for high-contrast imaging, revealing intricate details of emission nebulae even in areas affected by strong light pollution. This filter provides incredible contrast for all emission nebulae when used with CCD cameras or webcams, making it possible to capture stunning deep-sky images directly from urban environments. The filter is anti-reflection coated and plane-optical polished to ensure exceptional performance.
