Astronomik HA 12nm Narrowband Filter

Enhance your astrophotography with the Astronomik H-alpha 12nm filter. Capture stunning, detailed images of hydrogen-rich nebulae by isolating the deep-red H-alpha wavelength. This narrowband filter effectively blocks light pollution and enhances contrast, revealing intricate details of celestial wonders. Designed for both amateur and professional astronomers, the Astronomik H-alpha 12nm filter is your gateway to exploring the universe's hidden beauty. This H-alpha Filter is suitable for imaging of Hydrogen nebulas from observation sites with light pollution and from dark sites as well. The contrast between an object glowing at 656nm and the background is increased enormous! Due to the combination of the narrow bandwidth of 12nm and the high transmission of typically 96% the filter gives you an contrast boost, as all unwanted light from other wavelengths than 656nm is blocked form UV up to the IR. This results in an very dark background compared with any filters with a higher bandwidth
